Abstract

A non-algebraic cryptographic architecture. The non-algebraic cryptographic architecture is a logical implementation of a non-algebraic cryptographic engine (132) (sometimes referred to as a 'NACE'). The architecture uses a NACE in conjunction with cryptographic key lengths up to 2048 bits to achieve real-time encryption at speeds sufficient to permit wideband digital data to be decrypted (332) in real time thereby obviating the need for store-and-forward. The architecture is inherently parallel and can accept extended block lengths, which are several multiples of the length of the cryptographic key.
