Abstract

The invention provides a method and a device for discovering public and private key pairs. The method comprises the following steps: a second client sends a discovery request to a first client and stores the path information of a second ciphertext, wherein the second ciphertext is generated by encrypting a second public key pair by using a first public key pair, so that the first client obtains the second ciphertext, and uses a first private key pair to decrypt the second ciphertext to obtain a second private key pair, and feeds back the second private key pair to the second client. The discovery of the second public and private key pairs is achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for retrieving a public-private key pair. Background technique [0002] With the development of the information age, the demand for data encryption is getting higher and higher, and the use of public-private key pairs to encrypt data is becoming more and more widely used. Therefore, the storage of public-private key pairs becomes particularly important. [0003] The traditional method of storing the public-private key pair prints the public-private key pair on paper and places it in a safety device such as a safe. In this method, the backup of the public-private key pair is single, and multiple copies cannot be backed up, otherwise it is easy to leak and the storage medium is easily damaged. Once lost, it is not easy to find back. Contents of the invention [0004] In view of the above analysis, the present invention proposes a method and devic...
