Title:
EFFICIENT CRYPTOGRAPHIC KEY STREAM GENERATION USING OPTIMIZED S-BOX CONFIGURATIONS
Document Type and Number:
WIPO Patent Application WO/2014/088668
Kind Code:
A3
Abstract:
Application of a ZUC cryptographic functions in wireless communication includes receiving a data stream at the wireless communication apparatus and applying the ZUC cryptographic function to the data stream. The ZUC cryptographic function includes generating at least one multi-byte pseudo-random number that provides an index to one of a plurality of substitution boxes. Each of the substitution boxes is further based on one or more normative substitution boxes. The ZUC cryptographic function further includes retrieving a value from each of the substitution boxes using each byte of the multi-byte pseudo-random number, assembling the retrieved values into at least one substituted values, and generating at least one key value based on the substituted values, wherein the key value is used in applying the ZUC cryptographic function to the data stream. The method also includes processing the data stream after application of the ZUC cryptographic function.
