PERFORMANCE ANALYSIS OF AES AND BLOWFISH CRYPTOGRAPHIC ALGORITHMS

Information security plays very important role in storing and transmitting the data through unsecured channel. Cryptography plays a very important role in the network security to maintain the CIA triad that is Confidentiality, Integrity, Authentication and non-repudiation of information. Due to that security of information is much important in data storage and transmission process. Using cryptography, the data is encoded before sending it and decoded after receiving, Cryptographic algorithms are broadly divided into two types, symmetric key and asymmetric key cryptographic algorithms.There are various symmetric key algorithms available such as DES, AES Blowfish, Two fish, SAFER etc. This paper deals with the performance analysis of symmetric key cryptographic algorithms AES and Blowfish.
