Why is the symmetric key transmission a pivotal point of concern in quantum risk?
The symmetric key transmission process is crucial because, while symmetric keys (like AES) used to encrypt data are robust, the asymmetric exchange method used to share these keys (using algorithms like RSA or ECC) is vulnerable to quantum attacks.
How do quantum computers threaten smart contract execution and digital signatures?
Quantum computers can break mathematical algorithms used in digital signatures, enabling them to calculate private keys from public keys and forge digital signatures, which can compromise smart contract execution and digital signature integrity. Quantum- resistant cryptography can mitigate these threats by securing data against quantum computing attacks.
