Patent number: 8792860Abstract: A method of providing certificate issuance and revocation checks involving mobile devices in a mobile ad-hoc network (MANET). The wireless devices communicate with each other via Bluetooth wireless technology in the MANET, with an access point (AP) to provide connectivity to the Internet. A Certificate authority (CA) distributes certificates and certification revocation lists (CRLs) to the devices via the access point (AP). Each group of devices has the name of the group associated with the certificate and signed by the CA. A device that is out of the radio range of the access point may still connect to the CA to validate a certificate or download the appropriate CRL by having all the devices participate in the MANET.Type: GrantFiled: September 14, 2012Date of Patent: July 29, 2014Assignee: Certicom Corp.Inventors: William Daniel Willey, Simon Blake-Wilson

Patent number: 7352866Abstract: The present invention provides a method of authenticating a pair of correspondents in a communication system, such as in a mobile phone network by utilizing a blend of public-key cryptography and symmetric cryptography. Each session between the mobile phone and the network consists of public-key based mutual authentication and key exchange followed by symmetric-key secure data exchange.Type: GrantFiled: September 15, 2006Date of Patent: April 1, 2008Assignee: CerticomInventors: Prakash Panjwani, Simon Blake-Wilson

Publication number: 20080065878Abstract: A method for the secure transmission of an electronic message from a sender to a recipient. The method comprises receiving an encrypted sender transmission file transmitted from a sender computer station at a management server, wherein the sender transmission file comprises one or more signed hash values, a sender identifier and one or more recipient identifiers. The signature values are created from one or more message components associated with the electronic message composed at the sender computer station. The encrypted sender transmission file is decrypted; and a comparision is made with of the one or more signed hash values. For each of the one or more recipient identifiers, one or more recipient public keys; is retrieved.Type: ApplicationFiled: September 8, 2006Publication date: March 13, 2008Inventors: Michael Hutson, Derek Ritz, Charles Bouvette, Jeff Cummings, Rick Ensing, Simon Blake-Wilson, Russ Baird
