    摘要: A method and a device for managing a computer network, especially a technique for ensuring the security of a network. A computer network system in which computers are connected to each other through transmission lines, each computer stores the data which constitutes a moving type software exclusively used for security and transmitted together with a message when the computer transmits the message to another computer of the system, and executes the moving type software by using the stored data upon receiving a message from another computer.

    摘要: In the process of compressing and encrypting data, without an increase of processing time, a cipher capability is secured against the latest cryptanalysis such as differential and linear cryptanalyses. The differential and linear cryptanalyses are executed to collect plural pairs of plaintext and cryptosystem for the same key and perform the statistical operation for estimating the key. An input/output (I/O) process is executed to receive plaintext data and generate a different key for each data on the random number and set the key to a work key. The encrypted intermediate result or the pre-encrypted result is fed back to permit frequent changing of the work key. The changing operation is executed to change correspondence between the plaintext data and the compressed data in the compressing process.
