Abstract
An information security network provides a plurality of trusted authorities configurable in a rooted hierarchical structure. At least one of the trusted authorities is a superior authority and at least one of the trusted authorities are subordinate authorities. The trust authorities are capable of issuing digitally signed data structures, referred to as certificates. The superior authority is operative to generate policy control message data, such as separate message data or a certificate containing policy information, to dynamically vary policy control data to facilitate trust authority policy delegation among subordinate authorities. The policy control data includes, among other things, inter-trusted authority trust modification data to dynamically vary validation starting authorities among subordinate authorities.
