摘要：Example embodiments provide systems and methods for increasing the
cryptographic strength of an encryption or message-authentication-code- (MAC) generation technique. According to some embodiments, a MAC may be constructed around a shared secret (such as a random initialization number), thereby increasing strength of the MAC against brute force attacks based on the size of the shared secret. The MAC may be combined with randomized data, and may also be encrypted to further bolster the strength of the code. These elements (shared secret, MAC algorithm, and encryption algorithm) may be employed in various combinations and to varying degrees, depending on the application and desired level of security. At each stage, the cryptographic construct operates on the cyptographically modified data from the previous stage. This layering of cryptographic constructs may increase the strength of the group of contrasts more efficiently than applying any one construct with a larger key size or similar increase in complexity.
