A first entity stores an issuer digital certificate published by a certificate authority (CA) and signed by the issuer certificate; and also stores an old issuer digital certificate published by the CA prior to publication of the issuer digital certificate and an old first entity digital certificate signed by the old issuer digital certificate. The first entity attempts to initiate a secure communication session with a second entity by receiving a second entity digital certificate from the second entity via an electronic network, and sending either the first entity digital certificate or the old first entity digital certificate to the second entity based on which of the issuer digital certificate or the old issuer digital certificate is effective to authenticate the second entity digital certificate received from the second entity. The secure communication session is conducted only if the attempt to initiate the secure communication session is successful.
