摘要： A computer-implemented system and method for configuring and operating a white-box cipher is disclosed. In one implementation, the system employs a method for configuring pseudorandom data derived from a key to perform key-scheduling functionality associated with rounds of the cipher. Additionally, the system employs a method for generating white-box executable code, wherein the code hides the pseudorandom data by incorporating it into mathematical operations performed during execution of the rounds. Accordingly, the cipher is suited for white-box applications managing digital rights, such as decoding audio, video and other content.

摘要： An implementation of a technology, described herein, for facilitating the protection of computer-executable instructions, such as software. At least one implementation, described herein, may generate integrity signatures of one or more program modules—which are sets of computer-executable instructions—based upon a trace of activity during execution of such modules and/or near-replicas of such modules. With at least one implementation, described herein, the execution context of an execution instance of a program module is considered when generating the integrity signatures. With at least one implementation, described herein, a determination may be made about whether a module is unaltered by comparing integrity signatures. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要： The present invention leverages the invertibility of determinants of unimodular matrices to provide a universal hash function means with reversible properties and high speed performance. This provides, in one instance of the present invention, length controllable hash values comprised of vector pairs that can be processed as one instruction in a SIMD (single instruction, multiple data) equipped computational processor, where the vector pair is treated as a double word. The characteristics of the present invention permit its utilization in streaming cipher applications by providing key data to seed the ciphering process. Additionally, the present invention can utilize smaller key lengths than comparable mechanisms via inter-block chaining, can be utilized to double hash values via performing independent hash processes in parallel, and can be employed in applications, such as data integrity schemes, that require its unique processing characteristics.
