Planning and Construction of a Quantum Model of the SHA-1 Algorithm Using IBM’s Qiskit

The hash produced by a cryptographic hash function is inherently impossible to reverse-engineer or duplicate. You can protect yourself from hacking attempts more effectively with this. In a quantum environment, attacks on information systems would look significantly different, calling for a complete overhaul of current cryptographic practices. For the purpose of constructing a quantum-based Secure Hash Algorithm (SHA-1) from the ground up, a complete guide is provided to the design of quantum addition along with the associated circuits of XOR, AND, NOT, OR, MOD, CARRY, and SUM. To boost the efficiency of the standard SHA-1 algorithm, the q-SHA-1 is created in a Qiskit-based quantum environment. Experimental results from a wide range of conditions will be compared to evaluate the relative efficacy of the classical and quantum SHA-1 algorithms. However, it has been discovered that the execution time is highly dependent on the particular CPU type that is being used. A more powerful processor ought to cut down on the amount of time needed for the overall execution.
