在2009 CNCERT/CC安全年会上，中国移动通信集团公司网络部处长徐海东表示，移动互联网融合新凸显的安全面临网络安全、终端安全、业务安全三方面问题。徐海东还表示，移动互联网融合的安全对策可以有以下四点：
一是用户对网络透明，要抓住“可鉴权，可溯源”的技术优势，可以起到有效的威慑作用，降低各种安全威胁，提高网络的整体安全强度；
二是要关注网络自身安全，且对用户不透明，对用户隐藏网络拓扑，使得用户无法对网络节点发起攻击；
三是终端安全保护。对于智能终端的安全保护需要进行重点研究，由于智能终端的操作系统可能存在安全漏洞，在彩信、手机浏览网页、下载安装软件等多种情况下都可能感染病毒或遭到入侵；
四是业务的安全保护。互联网应用大幅增加后，通信对端更不可信，由此可能引发病毒感染、木马等一系列攻击，危害严重。需要对服务提供方进行严格认证，目前正在标准化的GBA/GAA是一种对业务服务器进行认证的有效解决办法。 Read more…

The world is changing quickly. It’s pleasure to see that China is now regarded as a major influence force of the whole world. That’s also true at the IT industry.
According to the report ,China is the fast-growing smartphone market. Furthermore, China has much more mobile phone subscribers than any other country in the world. Read more…
From insiders, the largest mobile carrier – China Mobile has got the first 3G license at China. Surely, it’s TD-SCDMA. It’s said that this betrays the determination of China government to respect the self intellectual property and encourage China enterprises to develop their own technologies.
TD-SCDMA is one of the three major 3G international standards, submitted by China enterprises.
It’s reported that China Telecom will get CDMA2000 and China Unicom will get WCDMA soon.
At Oct. 30, China Telecom, a giant telecom operator of China, host the 6th meeting for its multinational company customer meeting at Nanjing, Jiangsu province, south China. Tens of their MNC customers, including Cisco, Nokia, Ford, Sony and etc. attended the meeting. I joined as well on behalf of Lenovo.
At the meeting, China Telecom introduced its C+W strategy and demonstrate its new product offereing, e.g. global eye service, video conference service, remote training platform and etc.
We have talked about VOIP legal monitoring and source location. In H.323 , softswitch or IMS VOIP network, it can possibly be done through signaling analysis. But as to P2P VOIP, especially encrypted P2P VOIP such as SKYPE, it is very difficult to identify P2P voice traffic.
Traffic classification and traffic identification can be useful in both ISP and enterprise environment, as well as in various occasions:
Now there are two kinds of P2P traffic identification algorithms: transport layer based or payload based. Read more…
