Abstract: A flexible aes instruction set for a general purpose processor is provided. The instruction set includes instructions to perform a “one round” pass for aes encryption or decryption and also includes instructions to perform key generation. An immediate may be used to indicate round number and key size for key generation for 128/192/256 bit keys. The flexible aes instruction set enables full use of pipelining capabilities because it does not require tracking of implicit registers.

Abstract: Generally, the present disclosure provides technology modifying a first cryptographic cipher with one or more operations of a second cryptographic cipher. In some embodiments the technology leverages a mathematical relationship between representations of data used in the first and second ciphers to enable the substitution of one or more operations of the first cipher with one or more operations of the second cipher. The resulting modified cipher may in some instances exhibit improved performance and or security, relative to the unmodified first cipher. Methods, computer readable media, and apparatus including or utilizing the technologies are also described.

Abstract translation: 通常，本公开提供了通过第二密码密码的一个或多个操作修改第一密码密码的技术。 在一些实施例中，该技术利用在第一和第二密码中使用的数据的表示之间的数学关系，以使得能够用第二密码的一个或多个操作代替第一密码的一个或多个操作。 相对于未修改的第一密码，所产生的修改密码在某些情况下可能表现出改进的性能和/或安全性。 还描述了包括或利用这些技术的方法，计算机可读介质和装置。
