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. There are many other algorithms which are based on the hybrid combination of prime factorization and discrete logarithms, but different weaknesses and attacks have been developed against those algorithms.
