Shreyash Hatkar, Bhagyashri K. Pawar · 2016
Now a days people are dependent on the internet so security of data becomes a major issue including integrity. Data security is a very important aspect in this digital world. Cryptography came into the picture to provide data security. In cryptography, cryptosystem means a suite of cryptographic algorithms expected to execute a specific security most commonly for achieving confidentiality. Basically a cryptosystem consists of three algorithms: one for key generation, another for encryption and another for decryption. There are a number of algorithms using different methods to achieve security measures for data and information. This Paper elaborates an efficient and effective symmetric cryptographic algorithm using time-variant keys.
