Survey on Techniques Developed using Digital Signature: Public key Cryptography

The digital signature technique is essential for secure transactions over open networks. It is used in a variety of applications to ensure the integrity of data exchanged or stored and to prove to the recipient the originator's identity. Digital signature schemes are mostly used in cryptographic protocols to provide services like entity authentication, authenticated key transport and authenticated key agreement. This architecture is related with secure Hash Function and cryptographic algorithm In this paper we are going to make review about all those technique that are developed within last 5-10 years. And which are developed with the help of digital signature and based on public key cryptography. These techniques provides a better platform for security of data using cryptography. General Terms Safety, Key, Hiding, Symmetric, Signature, Stream, Block, Security, Algorithms.
