Tizen

The Tizen Association includes such well-known global vendors as Samsung, Intel, Huawei, Fujitsu, Panasonic. Smartphones and tablets are far from the main use of the system. There are offshoots of the platform also for smart TVs and wearables. Intel has focused on entertainment and automotive solutions, and South Korean Samsung is actively promoting solutions on Tizen for the Internet of Things.

Tizen is not only and not so much a mobile OS. It can control refrigerators, TVs, smartphones and tablets, smartwatches, single-board computers and other embedded devices. The platform is closely integrated with the Samsung ARTIK IoT ecosystem and all its capabilities can be checked now: order products online from the refrigerator control panel or use a smartphone to open the door to the hotel room, turn on the lighting, TV and set the temperature of the air conditioner. In addition to control using touch screens, a voice interface is being actively developed - soon the user will be able, for example, to order the stove to heat the soup.

Tizen in Russia

• Tizen (Russian distribution)
• Тайзен.ру (association) is a Russian consortium of companies developing the Russian distribution of the Tizen OS.

2024: Closure of the OS project for wearable electronics

In early June 2024, Samsung, after three years of work, curtailed a failed project to implement the Tizen operating system for wearable devices. The purchase of paid applications from this OS in the Galaxy Store will be suspended.

Samsung's entry into the smartwatch market began with the introduction of the Gear 2 and Gear 2 Neo watch line in 2014, which ran on Tizen OS. The company actively developed this system based on Linux, but although in 207 it was even able to bypass Android in the smartwatch market, interest in it from both users and software developers gradually faded. As a result, Samsung was unable to compete in the smartwatch firmware market with Apple's watchOS and Google's WearOS.

Samsung, after three years of work, curtailed the failed project to implement the Tizen operating system

Samsung announced that it is winding down the program and intends to completely stop selling Tizen-based smartwatches on September 30, 2024, from that day on it will not be possible to buy paid content for Tizen devices, including applications and dials. Download of free smartwatch updates on Tizen will be limited on May 31, 2025, and download of all purchased products from the Galaxy Store will be completely discontinued on September 30, 2025. In addition, in May 2025, Samsung will stop all services related to wearable devices on Tizen, with the exception of the Galaxy Store.

Although users will be able to continue to use smartwatches and already downloaded updates in the same mode, after the expiration of the announced period, they will no longer be able to receive even those programs for which they have already paid if they reset the watch settings. These announcements apply only to smartwatches released by Samsung before 2018, starting with the Galaxy Watch 4, released in 2021, all Samsung smartwatches run the Wear OS-based One UI Watch.^[1]

2022: Samsung closes Tizen mobile app store

In early January 2022, Samsung closed the Tizen app store for both newly minted and existing users. The company closed the registration and made the store available only to existing users, and they could only receive previously downloaded applications, and both categories of users cannot download and update applications.

2017

Over 27 thousand vulnerabilities in Tizen OS

Security researcher Program Verification Systems Andrei Karpov on July 17, 2017 announced the discovery of thousands of vulnerabilities in the Tizen OS. After examining only 3.3% of the operating system code using the PVS Studio parser, Karpov discovered about 900 problems. According to his calculations, the entire code, thus, can contain 27 thousand vulnerabilities.^[2]

'

I've researched over 2,400,000 lines of code (along with comments) and found 900 errors. The entire Tizen project, inclusive with third-party libraries, consists of 72,500,000 code (excluding comments) on C and C++. Consequently, I checked 3.3% of the code. Calculations: (72500000 * 900/2400000 = 27187), "says Karpov

.

The researcher notified Samsung of the problem and offered his help, but the company refused to conduct the study, stating that it had its own analytical tool, which is regularly used to analyze Tizen.

"Be that

as it may, we do not agree that there are 27,000 defects in Tizen," Samsung said in a response message.

Tizen 4.x

As part of this project, the kernel, interfaces (similar to the latest versions of iOS can be traced) and system development tools are being finalized. The first build of the Tizen 4.x is expected in June 2017, and the second is due in December. It is planned to include the.NET library from Microsoft, which will allow you to use VisualStudio and facilitate the development of applications for Tizen.

By the time Tizen 4.0 is released, Samsung is expected to have a global infrastructure for the Internet of Things ready: the ARTIK Cloud, hardware-independent.NET development tools, and a container (docker) for platform virtualization.

40 zero-day vulnerabilities

On April 5, 2017, it became known that there were more than forty zero-day vulnerabilities in Tizen OS, identified as a result of an experiment conducted by Amihai Neiderman, head of the research division of the Israeli company Equus Software, eight months ago.

The researcher decided to conduct a security audit of the Tizen OS - in his opinion, no one was interested in this issue. During the analysis, Neiderman identified more than forty Zero-day vulnerabilities in the OS and was horrified by the quality of the code. In his opinion, almost all system applications are vulnerable^[3]

According to Neiderman's statement, the developers Samsung did not bother themselves and borrowed a considerable part of the code from - operating system Bada the OS code base looks outdated.

That's probably the worst code I've seen in life. Everything that could have been done wrong was done wrong. Obviously, security-savvy people didn't even go through that code or write it. It's like hiring an understudy and letting him write software for you. Amihai Neiderman

However, most of the vulnerabilities are fresh: they are contained in code that has been written specifically for Tizen in recent years. For example, an expert managed to hack a Samsung Smart TV using a vulnerability in the Tizen Store application catalog - the equivalent of the Google Play Store. With the help of the Tizen Store, any malware can be delivered to the device, and due to the high privileges of the directory, the hacker's capabilities are not limited by anything, he gains full control over the device. And the heap overflow bug allows you to bypass Tizen Store authentication.

Studying the OS revealed incorrect use of the strcpy () function, implementation problems SSLenciphering-, due to which information is transmitted in clear text, many other vulnerabilities.

According to Neiderman, Samsung is planning the development of Tizen and something big is clearly being prepared for the OS.

It is highly likely that next year the Galaxy S9 will run on Tizen, but the OS is not mature enough for this. Amihai Neiderman

All the past months, the specialist has not been able to contact Samsung representatives, trying to report problems. Now that Neiderman has publicly spoken about Tizen's insecurity at the Security Analyst Summit, Samsung representatives have "noticed" the researcher and rushed to assure the public that work is underway to fix the vulnerabilities.

2015

Tizen officially released

On October 15, 2015, as part of the annual Samsung Enterprise Mobility Forum business event, Samsung introduced the Samsung Z3 smartphone based on Tizen OS and it became the focus of the forum.

One of the features of the OS that distinguishes Tizen from other operating platforms operating on the market in this time period is the maximum openness of the source code. This fact opens up wide opportunities for users and developers, allowing, if necessary, to increase the capabilities of the OS in accordance with specific tasks and needs.

Igor Kalaida, General Director of the Research Institute of SOKB, noted: "Tizen's strongest point is openness and the possibility of its further development in terms of interface and security. Working on this project, we saw quite a lot of potential for Samsung, as well as source codes, real developers with whom we continue to work closely. We also saw the company's desire to take into account the specifics of national regulatory documents in terms of safety. "

Igor Bogachev, vice president of the Skolkovo Foundation, said: " I support the idea of ​ ​ openness, and I like Samsung's efforts to really make Tizen OS open, including to the Russian market and Russian developers. In my opinion, Samsung has taken some very real steps. The most key is the initiation of the creation of the Russian Taisen Association, which will include the largest players in the IT industry. Tizen is a platform on which various applications and technologies for real business can be created. Tizen is not only a mobile platform, it is an operating system for the "Internet of Things," and it gives us great opportunities. To attract developers, the Skolkovo Foundation, together with Samsung, plans to hold contests for young developers, as well as help those teams that are already working with this operating system. "

Igor Agamirzyan, General Director and Chairman of the Board of RVC OJSC, stressed: "Tizen is a good example of balance in terms of benefits for the business community and for developers. An important condition for the development of the project will be the presence of a critical mass of new developers. "

Dmitry Komissarov, CEO of New Cloud Technologies, said: "Tizen is an interesting new operating system, and it is fundamental for us to participate in this project. This is primarily a corporate platform, and we plan to pre-install office and mail applications MyOffice on mobile phones on Tizen OS. It has every chance of obtaining a high level of certification and being in demand, both in the commercial sector and in the state. "

Alexander Galitsky, Managing Partner of Almaz Capital Partners, shared: "We were attracted by Tizen's end-to-end openness and the ability to implement a system approach to manage various categories of devices. This will give an additional incentive to new startups, allowing them to offer products and services, combining a large number of devices based on one OS. In this regard, we can expect interesting companies to appear in different industries. "

Elena Nechay, Director of Marketing and Products of the business market of MTS PJSC, said: "MTS is the leader of the corporate market in Russia and we see high mobility of corporate customers and their high requirements for information security. Samsung traditionally pays great importance to the corporate segment, offering the market innovative developments. Solutions based on Tizen, in our opinion, are easily integrated into existing services of mobile operators, which allows us to offer these products for corporate users in the future. "

Ilya Massukh, president of the Information Democracy Foundation, said: "The Tizen platform is open to further development, and there are already partners who are working on office packages and other applications. The creation of a development center in Skolkovo is the right step in this direction. In the future, the center will gather small teams that can offer a sufficient number of useful applications. This will ensure digital sovereignty and independence in the mobile world. "

Sergey Bugrin, head of the Russian office of Red Hat, declared: "Tizen is the only really open system based on Linux. At the same time, it is already certified by the FSTEC of Russia. The creation of applications based on Tizen will be a big innovative breakthrough in the Russian IT market. "

Samsung and Intel are developing Tizen

As of June 15, 2015, Tizen is a Linux-based platform developed with support from Samsung and Intel as an alternative to Android.

The first Tizen-based smartphone, the Samsung Z1, is sold only in West Asia as of June 2015. The Korean company plans to expand the sales market for Tizen smartphones, as well as release device models in other form factors.

The appearance of Tizen-based devices in Russia is expected in November 2015, said a TAdviser source familiar with Samsung's plans.

Application of the solution on the Tizen platform

2011: Samsung and MeeGo developers begin Tizen development

In September 2011, it became known that the developers of the platform for mobile devices MeeGo are starting a new project - Tizen. Two Linux development teams have announced plans to combine their developments to create a new software platform called Tizen.

In a statement, LiMo Foundation and Linux Foundation noted that Tizen is based on open source, accepted standards, and is a cross-architectural software platform supporting a variety of devices, including smartphones, tablets, smart TVs, netbooks, and automotive infotainment systems.

The release of the first implementation of Tizen was scheduled for the first quarter of 2012. According to the expectations of representatives of initiative groups, the first devices using this platform should have appeared on the market in mid-2012.

The technical management of the project will be led by Samsung Electronics (Samsung Electronics Rus) and Intel, the Linux Foundation said.

Morgan Gillis, executive director of the LiMo Foundation, noted that the organization he heads understands Tizen as a timely step towards change, uniting the largest proponents of creating Linux mobile systems in the new ecosystem, with an open understanding of the development of web applications that will assist device providers in their innovations and liberalize consumer availability for developers and service providers. "LiMo will keep its focus on providing the industry with broad support from manufacturers and a neutral ecosystem independent of services based on the spirit of open and unlimited opportunities personified in Linux," he stressed.

The mobile industry continues to perceive Linux and open source technologies as key factors in reducing the cost of developing devices, increasing flexibility and reducing time to market. Project participants expect Tizen to further enhance these effects based on availability to any category of devices and a powerful emphasis on open standards.

Jim Zemlin, CEO of the Linux Foundation, said the Linux Foundation is pleased to host the Tizen platform. "Open code-based platforms like Tizen are good for Linux as they improve its adoption on devices of different categories. We look forward to starting cooperation with the LiMo Foundation and its members in this project, "Zemlin said.

Tizen is the result of the integration of MeeGo software platforms, which were also developed by the Linux Foundation and LiMo.
