摘要： A novel symmetric cryptographic system for data encryption uses two different sets of (m.times.n) s-boxes in its round function in one embodiment, where m and n are different integers. It also includes a set of expansion boxes to expand a half data block in a specific way. The expansion boxes are also (m.times.n) s-boxes. The cryptographic system of the invention is used in a feedback mode for generating better key schedules from a key.

摘要： A system, method, and network interface obscures the existence of data encryption in a communication network is provided. A set of characters is generated by using a set of encryption keys as an input to a pseudo-random function. Each character corresponds to an index value. The encrypted data is divided into a plurality of parts. Each part is sectioned into a plurality of groups. Each group of the plurality of groups is encoded by mapping the group to a character in the set of characters according to its corresponding index value. The mapped characters are transmitted through the communication network.
