Sponge Function based Authentication Encryption technique (SAFE) using robust initialization vector and ChaCha stream cipher

Abstract

In current times there are various categories of encryption algorithms which work on different structure; like AES, TDES and DES works on symmetric key cryptography, RSA works on Asymmetric key cryptography; another technique which aims at increasing security of algorithm is authenticated encryption. It is difficult to compare algorithms of different category but there are some factors in which encryption algorithms of every category can be compared; namely, time to encrypt, time to decrypt, frequency table and mainly security. This paper aims at comparing one algorithm of each category and check which one is best. SAFE is taken from authenticated encryption, which is claimed to be better than AES when implemented on software. RSA is taken from asymmetric key cryptography, which is first of its kind and still considered as one of the best encryption algorithm. All these algorithms are first implemented using GO language and results are compared to find best results in time and security.
