Not changing the Video Conference protocols in existence, we embed a good encryption algorithm (PermutationCode) in the system to safeguard the information of Multimedia.
在不改变现有协议的前提下,嵌入性能良好的加密解密算法(排列码算法)来保障信息的安全;

Then supplies realization of Encryption Chip based on PermutationCode by EDA, and integrates the modular of signal gathering so the chip can be used in voice communication encryption.
In this paper, a permutationcode security algorithm based on the block cipher that is widely used in the data transmission system is put up after carefully studied the current encryption methods.
