Abstract
A method and apparatus for distributing Certificate Revocation List (CRL) information in an ad hoc network are provided. Ad hoc nodes in an ad hoc network can each transmit one or more certificate revocation list advertisement message(s) (CRLAM(s)). Each CRLAM includes an issuer certification authority (CA) field that identifies a certification authority (CA) that issued a particular certificate revocation list (CRL), a certificate revocation list (CRL) sequence number field that specifies a number that specifies the version of the particular certificate revocation list (CRL) that was issued by the issuer certification authority (CA). Nodes that receive the CRLAMs can then use the CRL information provided in the CRLAM to determine whether to retrieve the particular certificate revocation list (CRL).
