VoIP Information security public attention the founder of PGP put forward protective countermeasures

Phil Zimmermann, who was previously famous for writing pretty-Privacy email encryption, hopes that the newly completed secure Internet telephony program is as popular as the user's. Zimmermann has developed a prototype of an Internet telephony application that can encrypt calls and eliminate eavesdropping. He plans to release the prototype program July 28 at the black Hat briefings Information security conference in Los Angeles. "I'm releasing this program because I want to help shape the direction of secure VoIP," Zimmermann said in an interview. The full name of VoIP is the "Internet Protocol Voice Call" (Voice over internet Kyoto), which allows people to make calls via Internet connections. VoIP is increasingly popular because it is cheaper than traditional telephone services, and in some cases even free. Companies can use Cisco (Cisco BAE) products such as the implementation of their own VoIP services, consumers may be used Packet8, Vonage and other companies to provide special telephones, plug in the broadband network can be called. Other companies, such as Skype, sell internet telephony software used on personal computers. Most instant messaging applications also have VoIP capabilities. Recently, the security of VoIP system has become the attention of the public anxiety. Cisco pointed out in early July that the company's product potential several security vulnerabilities, may cause the enterprise uses the Cisco network Telephone system to be interrupted the service (Denial-of-service) attack. Research firm Gartner predicts that 97% of new telephone systems installed in North America over the next two years will be VoIP systems, or a mix of traditional telephony and VoIP technologies. Cisco claims to have sold about 5 million VoIP phones to customers around the world. Encryption of VoIP information, the current technology has been done. Today's technology, however, is the use of a public key-value encryption system, which is to provide digital identity authentication to both sides of the call, to ensure the security of the call, using the infrastructure PKI. But the construction and management of PKI is vast. The system created by Zimmermann does not use a PKI. He wants to set up a company to sell products made from this encryption technology and to authorize technology to other companies for their Internet telephony products. "I will have my own products and sign agreements with other companies to put technology on their products." "The security expert said that although his prototype program could be used to call, there were still some problems to be solved, a distance from the formal finished product. "The technology is not mature enough," he admits: "Encryption is Yozakku real, but VoIP client programs have some bugs," Zimmermann said. He hasn't named the application yet. His VoIP client program is based on the open source of the Shtoom VoIP telephony client, and then add Zimmermann encryption technology. Zimmermann has previously invested in the development of Internet telephony. Nearly 10 years ago, he launched Pgpfone, but a little beyond the times. He said: "At that time, the Internet is not ready."
