NOVEL 5G AUTHENTICATION KEY AGREEMENT WITH QUANTUM AND POST QUANTUM CIPHERKEY DYNAMIC ON TELECOMMUNICATION NETWORKS

Telecommunication engineering

The 5G telecommunication network security is based on the standard specified by 3GPP (3rd Generation Partnership Project) and on the security of the master key shared between the UE (User Equipment) and the operator. To authenticate to the network, the 5G-AKA (5G-Authentication Key Agreement) protocol uses mutual authentication. Users resp. operators use cryptography to verify the authenticity of the operator resp. users. However, knowledge of the master key can create a hacker network that can capture the traffic of users. The QPQ- CD module (Quantum and Post Quantum Cipherkey Dynamic) consists of modifying the 3GPP standard by adding a recurrent change of this key to each successful authentication. The quantum part of QPQ-CD will be formed by a quantum confusion technique based on the Hilbert QHT (Quantum Hilbert Transform) method and the Arnold QAT (Quantum Arnold Transform) method on 3 matrices. The Post-Quantum part of QPQ-CD will focus on multiple hashing methods. The 12 families of hash algorithm used will reduce the matrices to 256 bits. An optimizer based on a one-bit change and an effective probability selector perfect the choice of the next key. The effective probability of the key will be based on probability of extremity, probability of proximity, probability of a bit changed, and probability of disorder or binary entropy and probability of penalties. According to the order of its probabilities, the following key after QPQ-CD thus has the behavior: very far from the ends of the key (00 ... 000 and 11 ... 111); very far from the previous key; several bits changed and very messy from the point of view bit zero and bit one and the penalty of bad extremity proximity. One of the 5 approaches of selectors and key optimizer will be perfected to refine the result. By simulating on MATLAB several authentication tests, the probability of the extremity and proximity will both be greater than or equal to 50% and the probability in case of binary entropy and disorder will be close to 100%. The effective probability of selection at this time will be greater than 50%
