A Recent Study of Various Encryption and Decryption Techniques

In the era of internet & smart phone every day terabytes of data are being generated. Data security over internet during communication is a great challenge. Cryptography is an integral part of data security mechanism over the internet. Cryptography makes information unintelligible to an unauthorized person. Cryptography provides confidentiality and maintains integrity to genuine users. In the past year there are various cryptographic algorithms have been developed. But every user needs a cryptographic algorithm which has highest level of security and performance. There are several algorithms with a cost performance trade off. User can choose any cryptographic algorithms which is best with requirements. In this paper we proposed a recent study of various encryption and decryption techniques. We also compare some of the existing algorithms based on certain parameters
