Title: (EN) SYSTEMS AND METHODS OF AMBIGUITY ENVELOPE ENCRYPTION SCHEME AND APPLICATIONS
(FR) SYSTEMES ET PROCEDES UTILISANT UN PROTOCOLE DE CHIFFREMENT A ENVELOPPE D'AMBIGUITE ET APPLICATIONS
Abstract: front page image
(EN)


Ambiguity Envelope (AE) security (10) uses prior art encryption algorithms
(42) and prior art encryption keys (20) and provides systems and methods for
random-variant-keys (18) that are used in place of the prior art encryption
keys (20). In AE an ambiguity envelope (13) is created over the transmission
of data packets, so that no specific encryption key, as in prior art, is used
but random-variant-keys (18) are used that are distinct and separate for each
packet and may also be distinct and separate for each incoming and outgoing
packet. Random-variant-keys (18) have no mathematical relationship to each
other or to the prior art encryption keys (20). These random-variant-keys (18)
are not created, stored at either end or exchanged with each end of
transmission. The random-variant-keys (18) are only created at the time of the
actual use for encrypting or decrypting a data packet and not before and then
discarded after one time use. The AE use is applicable to wireless network
using wireless access points (100), cellular phone and data networks (200) and
ad hoc mobile wireless networks (400).
