With the rapidly development of computer network technology and the widely use of network technology in every walk of life, people transmit data through computer network more and more frequently, including all kinds of secret information ( for example, military secret ; bussiness secret ; personal private information ). today, as a result of poor security of our network system, we can not prevent the transmittied information from stealing and modifying unlawful. thus, the computer network technology is applied to our daily life restrictedly. recently, many network applications with voip ( for example msn messenger ; dialpad ; distributed multipoint multimedia conferences ) take no measures to encrypt their data
