SM3 Algorithm Knowledge
Introduction
SM3 is a cryptographic hash algorithm standard published by the State Cryptography Administration of China, used for digital signatures, message authentication codes, and random number generation.
Features
SM3 produces a 256-bit (32-byte) hash value and provides high security and computational efficiency.
SM3 Characteristics
- Compression: Messages of any length are compressed to a fixed length
- One-way: Difficult to reverse engineer the original message from hash
- Collision resistance: Hard to find two different messages with same hash
- Avalanche effect: Small changes in input cause significant changes in output
Applications
- Digital signatures
- Message integrity verification
- Random number generation
- Key derivation
- E-government systems
- Financial transaction systems
