Review on Symmetric and Asymmetric Cryptography

Abstract: As the technology is progressing, internet is growing day by day and it has became more vulnerable than ever. To prevent data from being tampered or viewed by third parties, cryptography is used. Cryptography has it’s roots from ancient egypt, where secret writings are developed to transfer messages. Now, modern cryptography is used to secure data over the network, which are classified into symmetric and asymmetric cryptography. Both cryptographic methods has it’s own limitations and advantages, which are further used to develop algorithms for better security. More and more efficient algorithms are developed which are discussed in this paper
