Abstract: -Network security and cryptography is a subject about how to protect information in digital form and to provide security services. The purpose of a digital signature is to provide a means for an entity to bind its identity to a piece of information. The common attacks on digital signature were reviewed. The first method was the RSA signature scheme, which remains today one of the most practical and versatile techniques available. Fiat-Shamir signature schemes, DSA and related signature schemes are two other methods reviewed. Digital signatures have many applications in information security, including authentication, data integrity, and non-repudiation was reviewed. Owing to the drawbacks of basic Cryptographic Systems, our focus turned towards Quantum Cryptography whose strength, secrecy and privacy lies in the Laws of Physics than current state of unproven mathematical assumptions in Classical Cryptography.
