Blockchain cryptography technology mainly involves six aspects: 1. Cryptographical hash function; 2. Digital signature; 3. Public key infrastructure (PKI); 4. Asymmetric encryption; 5. Symmetric encryption; 6. Zero-knowledge proof . Together, these technologies provide a strong security foundation for the blockchain, ensuring data integrity, transaction security and user identity authenticity.
What are the main aspects of cryptographic technology in blockchain?
Blockchain is a distributed ledger technology, and its security is based on the widespread application of cryptographic technology. It mainly involves the following aspects:
1. Cryptographic hash function
- One-way function, input data of any length and output a fixed-length hash value (summary).
- Collision irresistibility, that is, it is difficult to find two different inputs that produce the same hash value.
- For verifying data integrity and block linking.
2. Digital signature
- allows users to securely verify data.
- Private key and public key are used in pairs. The private key is used to generate the signature and the public key is used to verify the signature.
- Ensure the authenticity and non-repudiation of blockchain transactions.
3. Public Key Infrastructure (PKI)
- manages and distributes digital certificates.
- Digital certificates associate a public key with a person or entity.
- By verifying the digital certificate, you can ensure the authenticity of the other party's identity.
4. Asymmetric encryption
- uses different keys for encryption and decryption.
- The public key is used for encryption and the private key is used for decryption.
- Widely used for key exchange and secure communication.
5. Symmetric encryption
- uses the same key for encryption and decryption.
- Faster and more efficient than asymmetric encryption.
- Usually used for data transmission and storage.
6. Zero-knowledge proof
- allows an individual to prove possession of certain information without revealing the actual information.
- Used to protect privacy and enhance the scalability of blockchain.
These cryptographic technologies work together to provide a strong security foundation for the blockchain, ensuring the integrity of data, the security of transactions, and the authenticity of user identities.
