In today's scenario, where everything is internet based, there is a huge demand for data security. A large number of cryptographic techniques are available to handle this problem. To increase data security, data can first be compressed using compression techniques and then encryption techniques can be applied. In this paper, we are proposing two new algorithms for encryption in which we have incorporated the concept of diffusion and confusion. The algorithms are based on Transposition cipher, Substitution cipher and Symmetric Key Encryption. Brute force on these algorithms can't be done so easily. These can be applied along with data compression to get more security.
