Kylin () is an operating system developed by academics at the National University of Defense Technology in the People's Republic of China since 2001. It is named after the mythical beast ''qilin''. The first versions were based on FreeBSD and were intended for use by the Chinese military and other government organizations. With version 3.0 Kylin became Linux-based, and there is a version called NeoKylin which was announced in 2010. In 2013, it was announced that a new Linux-based operating system with the same name would be released using Ubuntu. The first version, Ubuntu Kylin 13.04, was released on 25 April 2013. ==FreeBSD version== Development of Kylin began in 2001, when the National University of Defense Technology was assigned the mission of developing an operating system under the 863 Program intended to make China independent of foreign technology. The aim was "to support several kinds of server platforms, to achieve high performance, high availability and high security, as well as conforming to international standards of Unix and Linux operating systems."〔 It was created using a hierarchy model, including "the basic kernel layer which is similar to Mach, the system service layer which is similar to BSD and the desktop environment which is similar to Windows."〔 It was designed to comply with the UNIX standards and to be compatible with Linux applications.〔 In February 2006, "China Military Online" (a website sponsored by PLA Daily of the Chinese People's Liberation Army) reported the "successful development of the Kylin server operating system", which it said was "the first 64-bit operating system with high security level (B2 class)" and "also the first operating system without Linux kernel that has obtained Linux global standard authentification by the international Free Standards Group". In April 2006, it was said that the Kylin operating system was largely copied from FreeBSD 5.3. An anonymous Chinese student in Australia, who used the pseudonym "Dancefire", carried out a kernel similarity analysis and showed that the similarities between the two operating systems reached 99.45 percent. One of Kylin's developers confirmed that Kylin was based on FreeBSD during a speech at the international conference EuroBSDCon 2006. In 2009, a report presented to the US-China Economic and Security Review Commission stated that the purpose of Kylin is to make Chinese computers impenetrable to competing countries in the cyberwarfare arena. The ''Washington Post'' reported that: China has developed more secure operating software for its tens of millions of computers and is already installing it on government and military systems, hoping to make Beijing’s networks impenetrable to U.S. military and intelligence agencies. The deployment of Kylin was said to have "hardened key Chinese servers".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kylin (operating system)」の詳細全文を読む スポンサード リンク
