Abstract


Nowadays every communication and data exchange has been digitized. So everyone think about privacy and security. In this paper we are highlighting the need of security in daily data transmissions and the role of cryptography in order to handle demands of today’s secure world. We study various cryptographic techniques that can be used and applied for our needs. This also initiates the comparison of security level with the other methodologies. There are different cryptographic methodologies available to perform uniquely specified tasks like- encryption, decryption, key agreement and digital signatures. In this paper we review the study of different encryption schemes and its usage along with different key management techniques and the application of digital signature with its complete operational principle that are used in daily life as a part of secure communication.

Keywords


Cryptography, Digital signature, Encryption, Decryption, Key exchange.
