Abstract: A method of communicating in a secure communication system, comprises the steps of assembling a message at a sender, then determining a frame type, and including an indication of the frame type in a header of the message. The message is then sent to a recipient and the frame type used to perform a policy check.

Abstract: A method and system for distributed security for a plurality of devices in a communication network, each of the devices being responsible for generating, distributing and controlling its own keys for access to the communication network and using the keys to establish a trusted network, each device's membership to the communication network being checked periodically by other devices by using a challenge response protocol to establish which devices arc allowed access to the communication network and the trusted network.

Abstract: There are disclosed systems and methods for creating a self-signed implicit certificate. In one embodiment, the self-signed implicit certificate is generated and operated upon using transformations of a nature similar to the transformations used in the ECQV protocol. In such a system, a root CA or other computing device avoids having to generate an explicit self-signed certificate by instead generating a self-signed implicit certificate.

Abstract: Accelerated computation of combinations of group operations in a finite field is provided by arranging for at least one of the operands to have a relatively small bit length. In a elliptic curve group, verification that a value representative of a point R corresponds the sum of two other points uG and vG is obtained by deriving integers w,z of reduced bit length and that v=w/z. The verification equality R=uG+vQ may then be computed as −zR+(uz mod n)G+wQ=O with z and w of reduced bit length. This is beneficial in digital signature verification where increased verification can be attained.
