Wireless communication using compact certificates

摘要

A method and communications system for generating and using compact digital certificates for secure wireless communication. Each compact certificate includes a digital signature and only a portion of the data used in generating the signature. The remaining certificate data is pre-stored on one or more wireless devices for which secure communication is desired. Upon receiving a compact certificate, the wireless device authenticates the certificate using its digital signature along with both the data contained in the certificate and the data pre-stored on the wireless device. This approach permits secure connections to be established between wireless devices using relatively small digital certificates.
