Post-quantum cryptographic algorithms differ significantly from RSA and elliptic curves in key size, computational overhead, and protocol interaction patterns, and the way existing systems integrate them needs to be redesigned.

VerifiedRSA encryption relies on the difficulty of large integer factorization, elliptic curve cryptography relies on the discrete logarithm problem, and cryptographic security is built on the assumption that certain problems are computationally hard to solve.72% similarUnverifiedHybrid encryption mode runs both classical and post-quantum algorithms simultaneously, ensuring that even if the post-quantum algorithm has unknown weaknesses, the system's security remains at least equivalent to that of the classical algorithm.72% similarUnverifiedPost-quantum algorithms have larger key and signature sizes, which may affect protocol design, storage formats, and network transmission, so migration is not simply a library replacement.70% similarUnverifiedWhat quantum computing truly threatens is asymmetric encryption algorithms, such as RSA and Elliptic Curve Cryptography (ECC).68% similarVerifiedSM2 is based on elliptic-curve cryptography (ECC) with a key length of 256 bits; its security is equivalent to RSA-2048 but with higher computational efficiency, and it is commonly used for digital signatures and key exchange65% similar
