High Secure Initial Authentication Protocol based on EPNR Cryptosystem for Supporting Radiation Monitoring System

Abstract

Radiation monitoring data is very important to support the safety of nuclear installation. The data should be ensured generated and supplied by an authenticated sensor. The new sensor should apply mutual authentication to server before joint the system. This research proposes a high secure authentication protocol based on Eight Prime Number of Modified RSA Algorithm (EPNR) method as certificateless mechanism to protect authenticity and confidentiality of sensor's identity. The main advantages of the protocol are designed for simpler direct point to point connection, using one-time random keys, and implementing five-barrier data protection mechanism. Its performances in context security, running time, and Quality of Services have been compared to other models. The proposed protocol is faster 29.9 times in random key generation, 7.27 times in encryption, and 11.1 times in decryption duration, compared to the others model based on RSA scheme. It has better performances in throughput and delay time. It also has enhanced resistance to statistical, replay, and MITM attack.

Design a Lightweight Authentication Encryption Based on Stream Cipher and Chaotic Maps with Sponge Structure for Internet of Things Applications

“…The birthday bound for most authentication encryption systems, where 𝜎 is the ciphertext block length and n is the block length, is 𝑂( 𝜎 2 2 𝑛 ) , and it guarantees security up to that point.…”

“…At last the proposed investigates the security beyond birth bound (BBB) feature where block length n=128 and it guarantees security up to 𝑂( 𝜎 2 2 128 ), where 𝜎 is the length of the ciphertext block.…”

“…Cryptography has divided into stream cipher and block cipher. Stream cipher is easier to implement in hardware and software than block cipher, and it also features quick encryption and decryption operations with little to no error propagation [1,2].…”
