What is RSA Algorithm in Network Security?
/ May 20, 2018

RSA Algorithm is christened after its joint inventors, Ron Rivset, Adi Shamir and Leonard Adleman who invented it during 1977. This algorithm is the first of its kind that can be used for public key encryption as well as digital signatures. The RSA cryptosystem is the most widely-used public key cryptography algorithm in the world. It can be used to encrypt a message without the need to exchange a secret key separately. The RSA algorithm can be used for both public key encryption and digital signatures. Its security is based on the difficulty of factoring large integers. Party A can send an encrypted message to party B without any prior exchange of secret keys. A just uses B’s public key to encrypt the message and B decrypts it using the private key, which only he knows. RSA can also be used to sign a message, so A can sign a message using their private key and B can verify it using A’s public key. RSA algorithm is asymmetric cryptography algorithm. Asymmetric actually means that it works on two different keys i.e. Public Key and Private Key. As the name describes that the Public Key is given to everyone and Private Key…
