Security Arguments for Digital Signatures and Blind Signatures

摘要

Since the appearance of public-key cryptography in the seminal Diffie- Hellman paper, many new schemes have been proposed and many have been broken. Thus, the simple fact that a cryptographic algorithm withstands cryptanalytic attacks For several years is often considered as a kind of validation procedure. A much more Convincing line of research has tried to provide "provable" security for cryptographic Protocols.
