Abstract
Methods and apparatus are provided for an asymmetric encryption scheme with expiring revocable certificates having a predefined validity period. Communications between two devices are secured by obtaining an expiring revocable certificate; and securing said communicating with said expiring revocable certificate using asymmetric encryption. A prior expiring revocable certificate can be revoked when a new expiring revocable certificate is issued to at least one device. The expiring revocable certificate has a predefined validity period (based, for example, on a longest expected connection drop-out duration). A new expiring revocable certificate is requested at least once for each predefined revocation period. The expiring revocable certificate is revoked after the predefined revocation period, for example, only if a connection between the two devices is maintained.
