Abstract
According to one embodiment of the present invention, a method of updating a certificate trust list on a first endpoint includes receiving an initial certificate trust list at the first endpoint. The initial certificate trust list includes authentication data for at least a second endpoint. Digitally signed information is received at the first endpoint and authentication is initiated against the authentication data for the at least a second endpoint. The authentication occurs only if the digital signature is complementary to the authentication data for the at least a second endpoint. After successful authentication, the initial certificate trust list is updated with the information to yield an updated certificate trust list.
