Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For a better understanding of the present solution, some terms and processes are parsed by way of example below:
public key: is a public key that is public to all nodes and without any risk, the public key being used for confirmation of a receipt in a transaction, similar to a "payee" in a banking transaction. It is also often used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key.
Private key: refers to a key associated with an address, a string of 256-bit numbers that is known only to the private key owner, used for digital signing, confirming ownership of the transaction, similar to the "signature" in banking transactions.
Let A be the client and B be the server
Public key encryption
The encryption refers to encryption of other algorithm forms such as asymmetric algorithm encryption, symmetric algorithm encryption and the like on a piece of data; and assuming that A is a client and B is a server, the encryption process is that A and B carry out communication encryption, B needs to generate a pair of secret keys, B holds a private key for A, A uses the public key of B to encrypt the content to be transmitted, and then B receives ciphertext and decrypts the content through the private key of B.
Private key decryption
Decryption is to analyze encrypted data by a relevant logic operation to become data before encryption.
Private key signature
Signing means that relevant characters are added to data, such as generating a data abstract and the like, and then signature verification is carried out, wherein the signing aims at preventing information from being tampered; a sends a message to B, A calculates the message digest of the message, then encrypts the message digest using its own private key, and the encrypted message digest is the signature (A encrypts the message digest with its own private key to become the signature).
For example:
public key signature verification
B after receiving the message, it will also use the same method as A to extract the message abstract, then use A's public key to decrypt the signature, and compare with the message abstract calculated by oneself, if the same, it indicates that the message is A sent to B, at the same time, A cannot deny the fact that it sent the message to B (B uses A's public key to decrypt the signature file, called "signature verification")
