US20040086117-A1

A method for performing computations in a mathematical system which exhibits a positive Lyapunov exponent, or exhibits chaotic behavior, comprises varying a parameter of the system. When employed in cryptography, such as, e.g., in a pseudo-random number generator of a stream-cipher algorithm, in a b ...

Methods for Generating Identification Values for Identifying Electronic Messages.
Harness Dickey & Pierce,
November 29, 2007:
US20070277043-A1

In a method for generating an identification value for identifying an electronic message by application of a first hash function with fixed compression that compresses n blocks of data into a number of blocks, which is smaller than n, the hash function is repetitively applied in a tree-structure com ...

Fabrication of computer executable program files from source code.
Harness Dickey & Pierce,
October 1, 2009:
US20090249492-A1

A method for protecting a computer program against manipulation and for shielding its communication with other programs against eavesdropping and modification is presented. The method comprises the creation of individualized program copies to different groups of users, the insertion of or the deriva ...
