Compact Quantum Circuit Design of PUFFIN and PRINT Lightweight Ciphers for Quantum Key Recovery Attack

Quantum computing plays a vital role in the next generation platforms as researchers have achieved quantum supremacy by proving that computers can outperform classical computers. These high performance will pose serious threat to security of conventional cryptographic algorithms. The secret key algorithms when implemented circuits easily be recovered with help Grover search algorithm. Grover’s algorithm requires low cost implementation order mount recovery attack successfully. Hence using is an active area research. This work proposes novel circuit two lightweight block ciphers namely PUFFIN and PRINT for first time literature In-place method used optimize resources these which helps build compact without extra ancilla inputs. metrics considered this quantify proposed are number gates, cost, latency qubits. In addition, also estimated attacks on implementations Grover-based
