SYMMETRIC STREAM CIPHER

摘要

A method, an apparatus, and a computer program product for symmetric stream encryption are provided. An encryption chain is obtained from a real random number generator (RRNG) and stored in memory. A vector key is identified based on numbers obtained from a fast, large period pseudo-random number generator. A set of encryption keys are identified from the encryption chain using the vector key. Strings of clear text are encrypted using the encryption keys.
