Abstract
A system and method for the generation of composite private keys are provided. First and second bitstreams are retrieved from an addressable cryptographic table by deriving addresses in the addressable cryptographic table from an initial instruction, accessing first and second bit values stored at addresses belonging to the derived addresses in the addressable cryptographic table, and outputting the first bit values as the first bitstream and the second bit values as the second bitstream. The first bitstream is concatenated with data from the first bitstream to form a data stream having a desired length and the second bitstream is concatenated with data from the second bitstream to form a selector stream having the desired length. A first composite encryption key having a length longer than the first and second bitstreams is formed by selecting values of the data stream identified by corresponding bit values of the selector stream.
