Abstract
A technique for encrypting and decrypting a data message is described herein and includes a stream cipher, a block cipher and a key generation embodiment which use a process of Summary Reduction. This overall technique uses a secret key to generate ciphertext from plaintext and in doing so, the technique isolates the nature of the secret key values from the nature of the cipher text created.
