<p>An information security transmission system is provided, which includes a first information device and a second information device. The first information device obtains at least authentication information and connects with the second information device via a network for information exchange. The system obtains the key pairs for encryption and decryption with or without the help of certification center, builds an information transmission security channel, encrypts and decrypts for the transmitted information and keeps the security of the transmitted information. The first information device has a first dynamic encoder/decoder and the second information device has a second dynamic encoder/decoder respectively. The first dynamic encoder/decoder and the second first dynamic encoder/decoder encode dynamically and ensure a one-time completion of error-free transmission and safety of the transmitted information with mechanism of auto error-detection and mechanism of auto error-correction. And the transmitted information has an access limitation, which makes the receiving party access the transmitted information in the limitation of an accessing condition and delete all the transmitted information when exceeding the accessing limitation so as to prevent the transmitted information from out-flowing.</p> |
