US08468351
(4 worldwide citation)

A method for protecting a digital document and user data typed into a digital document is presented. The method comprises computation of an authentication tag when the document is sent from a server. A similar authentication tag is computed when the document is shown on a client. When another docume ...

WO/2005/076522
(1 worldwide citation)

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 ...

A method of performing mathematical operations in an electronic device, a method of generating pseudo-random numbers in an electronic device, and a method of encrypting and decrypting electronic data.
Cryptico,
November 12, 2003:
EP1360767-A2

A method of performing numerical computations in a mathematical system comprises expressing the mathematical system in discrete terms, using fixed-point variables in the computations, and extracting a sub-set of digits of a number. The sub-set of digits may represent a random or pseudo-random number ...
