Publication number: 20120257752Abstract: An improved encryption and digital signature system and method in accordance with the invention reuses an encryption ephemeral key pair from an encryption process in a digital signature process. The reuse of the encryption ephemeral key pair in the digital signature process advantageously results in reduced byte size of the digital signature and reduction of costly computation overhead. In a preferred embodiment, the invention is based on the El Gamal encryption scheme and the Nyberg-Rueppel signature scheme. The present invention is particularly useful for operation in conjunction with small communication devices having limited processing and storage, wherein such devices may communicate via bandwidth sensitive RF links.Type: ApplicationFiled: June 11, 2012Publication date: October 11, 2012Applicant: RESEARCH IN MOTION LIMITEDInventor: Herb A.

Publication number: 20120042161Abstract: Electronic messages are sent from a sending system to an identified recipient and are encrypted using information contained in a certificate for that recipient. An electronic device and method are provided for detecting receipt of a command to initiate transmission of a composed message to a recipient, and after said detection but prior to transmitting the message, determining that no valid digital certificate for said recipient is available at the communication device; retrieving a valid digital certificate for said recipient from a source over a network; and encrypting said composed message using the valid digital certificate; then initiating transmission of the encrypted, composed message to the recipient. Retrieval of the valid digital certificate can include repeated retrieval and validation of certificates until a valid certificate is obtained.Type: ApplicationFiled: October 25, 2011Publication date: February 16, 2012Applicant: RESEARCH IN MOTION LIMITEDInventors: Michael S.

Patent number: 8074066Abstract: Electronic messages are sent from a sending system to an identified recipient and are encoded using information contained in a certificate. A key store is accessed by a messaging application to determine if a certificate associated with the recipient is present. If no certificate is present in the key store the messaging application accesses one or more certificate services to obtain a certificate. Where validation of the retrieved certificate is required, the messaging application invokes a certificate validation process. One or more further certificates are obtained by the messaging application where the retrieved certificate is invalid.Type: GrantFiled: January 24, 2005Date of Patent: December 6, 2011Assignee: Research In Motion LimitedInventors: Michael S. Brown, Michael G. Kirkup, Herb Little
