Title:
SECURITY SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2005057372
Kind Code:
A3
Abstract:
A first embodiment provides a process and system for simple, secure exchange of random numbers between two devices by combining a random number and a secret code (e.g., password) to generate a first challenge code, extracting the random number using the password at the second device, combining the first random number with a second random number, and returning the combination to the first device, which extracts the second random number from the second challenge code using its first random number. A CRC can be added to authenticate the sender. Another embodiment provides a system and method for generating a seedless pseudo-random number. The Yet another embodiment provides a system and method for generating data encryption coding with variable clocking.
