Mathematical analysis and simulation of multiple keys and S-Boxes in a multinode network for secure transmission

摘要

The requirement of data security is an important parameter for all organizations for their survival in the world. Cryptography is the best method to avoid unauthorized access to data. It involves an encryption algorithm and the keys that are being used by the users. Multiple keys provide a more secure cryptographic model with a minimum number of overheads. There are various factors that affect the security pattern such as the number of keys and their length, encryption algorithm, latency, key shifting time, and users. In this paper, a new approach is proposed for generating keys from the available data. The analysis of various times, such as encryption, decryption, key setup, processing, and key shifting times, has been done. The model takes minimum time to replace the faulty keys with the fresh keys. In this paper, we consider all the above-mentioned factors and suggest an optimized way of using them.
