Forward Secure Non-Interactive Key Exchange

摘要: Exposure of secret keys is a major concern when cryptographic protocols are implemented on weakly secure devices. Forward security thus way to mitigate damages such an event occurs. In forward-secure scheme, the public key indeed fixed while updated with one-way process at regular time periods so that scheme ensured for any period prior exposure, since previous cannot be recovered from corrupted one. Efficient constructions have been proposed digital signatures or public-key encryption schemes, but none non-interactive exchange protocols, non-interactivity makes them quite vulnerable information evolve execution another
