Digital Signatures is the first comprehensive account of the theoretical principles and techniques used in the design of provably secure signature schemes. In addition to providing the reader with a better understanding of the security guarantees provided by digital signatures, the book also contains full descriptions and detailed proofs for essentially all known secure signature schemes in the cryptographic literature. A valuable reference for students, professors, and researchers, Digital Signature Schemes can be used for self-study, as a supplement to a course on theoretical cryptography, or as a textbook in a graduate-level seminar.
