ALGORITHM-AGNOSTIC APPROACH FOR SYSTEMATICALLY HARDENING ENCRYPTION

摘要

Embodiments are directed towards an encryption-agnostic approach to systematically hardening an encryption scheme. Plaintext, P, is received as a series of bits by a first computing device that may apply a transformation function f(C, H, Plaintext), where C and H are non-negative integer values, to the plaintext to generate hardened plaintext Q. The transformation function is directed towards selectively interleaving randomly generated bits through the series of bits in P based on values of C and H. Pre-pending or appending of randomly generated bits may be selectively turned on/off using input flags A and U. CH hardening parameters that include C and H, and flags A and U may be combined with the hardened plaintext Q. The combination may then be encrypted using any of a variety of encryption schemes. A reverse process is employed to obtain the CH parameters, which are used to extract the plaintext from Q.
