Recently, some media sources said that the United States refused to issue a visa to a Chinese WAPI (Wireless Local Area Network Security Standard) proposal technical expert, making it impossible to participate in the International Organization for Standardization meeting held in the United States. It is said that this kind of thing happened more than once, and there was a precedent in 2004. The wireless local area network ( WLAN ) in the 3G era is considered to be the hottest market, and China Telecom, Mobile and Unicom are investing heavily in building their "wireless city" strategy. However, the international standard for this piece of "cake" is WiFi, which is mastered by major companies such as Intel and IBM, or "IEEE 802.11", which is now the 802.11i version. In 2003, China launched its own standard WAPI, and then China has been working hard to make WAPI an international standard, but the road is bumpy. In 2004, China announced that all foreign manufacturers selling in China must install WAPI compulsorily. This mandatory requirement was met with fierce opposition from Americans. Subsequently, China announced that this requirement would be postponed indefinitely. However, China does not seem to be "WAPI is only a weapon for trade restrictions" as Americans think it is, but sincerely believes that it can become a standard. The 2005 Frankfurt Conference was a humiliation. Americans said at the meeting, no The WAPI issue (ie 1N7506 proposal) will be discussed, and the Chinese will leave the show angrily. But WAPI is a bit like "Zeng Guofan's feeling", and has been defeated and fought repeatedly. In 2006, the overwhelming majority of the International Organization for Standardization (ISO) rejected WAPI's proposal to become an international standard, and IEEE 802.11i completely won. However, the Chinese are not completely obsessed with the idea. The government has adopted a strategy of "market expansion to foster standard competitiveness"-the inventor of this idea is a Korean, and requires mobile phone-based device manufacturers to use " While accepting WIFI, the "bundle" method must also accept WAPI: In the past, foreign mobile phones sold in China (non-parallel imports) did not have WIFI function. If you bring WIFI in the future, you must also accept WAPI. China claims that WAPI is comparable to WIFI. The advantage is that it is safer, which is true. However, this is mainly compared with the WEP encryption mechanism of WIFI in 2003, WEP encryption and simple, according to the test can crack the password in a few minutes. WAPI uses a symmetric encryption algorithm (elliptic curve cryptographic algorithm and block cipher algorithm), which is a centrally controlled closed identity authentication mechanism, the threshold will be relatively high, but it is not very convenient. However, we must know that WIFI has now entered the RSN stage from WEP encryption evolution, and cracking it is no longer an easy task. In other words, WIFI is not as insecure as Chinese experts claim. Importantly, WAPI is not like TD-SCDMA. China launched TD and soon became the world's three major standards together with WCDMA and CDMA2000, because TD is at least like a standard, especially in terms of flexible utilization of spectrum resources. But WAPI is more like WIFI improving on the local function of encryption, while most other functions are overlapping and the same. In other words, WAPI is more like a derivative of WIFI. At first, many Americans believed that China's attempt to launch WAPI was to increase the "chip" for other trade negotiations, rather than really want to make it a standard. When Chinese people really push WAPI as the standard, Americans change from wondering to treating WAPI roughly, which is regarded as unreasonable trouble. The Chinese have always been anxious about the standard right to speak and suffocated to pay a lot of patents and licensing fees, just like the United States tolls on the information highway. China is also building toll gates in front of its own door, or take a slice of the soup, or everyone will charge The station was cancelled and no payment was made. However, the rules of the game are not played in this direction. China is now promoting WAPI with the "WIFI + WAPI bundling" method, trying to expand the manufacturer's camp (it is said that Apple mobile phones will also join), but the problem is that the tying products cannot compete with the purchase products because of the tying. Moreover, the interests of WAPI are concentrated on the main bodies of the National Cryptography Administration, Xidian Jietong Company, and some scientific research institutes. Even operators feel that it is too costly to adopt WAPI. The implementation of a standard is actually to establish a game platform, so that all players feel valuable, rather than being manipulated. Only in this way can the standards be truly "protected". 64V Battery Pack ,Lithium Battery Box,Lithium Power Pack,Jackery Battery Pack Zhejiang Casnovo Materials Co., Ltd. , https://www.casnovonewenergy.com
