Background/objectives: Encryption is one of the most important factors of any security structure. Data cannot be protected without an efficient encryption technique. Different encryption algorithms are available nowadays that apply techniques such as encrypting using symmetric or asymmetric keys, using stream or block ciphers, and others such as Feistel networks, substitution, and permutation, etc. Methods/statistical analysis: We have analysed the existing algorithms so as to get the problem. Findings: The proposed algorithm will solve the problem of maintaining the authenticity of the sender as another third party cannot send a message in the former’s name, as was the problem with earlier algorithms such as DES. Improvements/applications: The main idea of performing this research was to propose an algorithm that can encrypt a message with the sender’s private key and the receiver’s public key together and the same can be decrypted using the receiver’s private key and sender’s public key.
Keywords: S-box, P-box, Feistel Networks, DES
