Abstract

Quantum Implementation of SHA-1 and MD5 with three other Quantum Resistant Techniques This paper presents the quantum adaptation of Secure Hash Algorithm 1 (SHA-1) and Message Digest 5 (MD5) using IBM?s Qiskit framework, evaluating their computational performance against classical hashing techniques and post-quantum cryptographic schemes, including eXtended Merkle Signature Scheme (XMSS), Leighton-Micali Signature Scheme (LMSS), and SHAKE-256. These three algorithms are the NIST certified quantum resistant hashing techniques. Several quantum circuits are designed to implement fundamental cryptographic operations such as XOR, AND, OR, addition, and modular arithmetic, enabling a quantum-friendly transformation of these hashing algorithms. Experimental results indicate that quantum implementations exhibit significant computational overhead due to circuit depth, gate constraints, and hardware limitations. These findings contribute to understanding the feasibility of quantum hashing and post-quantum cryptographic frameworks and their role in securing future authentication systems.
