ip key management mechanism with divergenzer increase entropy barrier against computing crypto analysis

摘要

A key generator ( 51, 61 ) generates, from an IP-key ( 11 ) for entering a closed IP network ( 1 ), a set ( 52, 62 ) of session keys ( 53, 63 ) indexed for identification, an index pointer ( 71, 72 ) points an index (i, j) to identify a session key ( 53, 63 ), the set ( 52, 62 ) of session keys has a divergence barrier incorporated therein for barring a computational approach to any session key ( 53, 63 ), and an unbar data set (i, j, 62 ) unbars the divergence barrier.
