Risk assessment involves understanding the mathematical foundation of existing cryptographic schemes and evaluating their susceptibility to quantum algorithms like Shor’s and Grover’s. Cryptographic algorithms relying on the integer factorization problem (e.g., RSA) or the discrete logarithm problem (e.g., ECDSA) are quantum-broken. For Ethereum wallets:
Shor’s algorithm enables rapid factorization of RSA moduli, reconstructing private keys.
Grover’s algorithm accelerates brute-force attacks on symmetric key algorithms, reducing effective key lengths.
Graph Description: This figure illustrates the computational advantage quantum computers have over classical systems in breaking RSA and ECDSA through Shor’s algorithm. The graph shows an exponential increase in vulnerability as quantum hardware scales.
Organizations assess risks using metrics such as quantum volume (a measure of quantum computer performance) and projected timelines for scalable quantum systems. They then prioritize transitioning vulnerable systems to quantum-resistant alternatives.
