Abstract

The embodiment of the invention provides a decryption method and device. The method comprises: a first decryption terminal acquiring a to-be-decrypted message; the first decryption terminal encapsulating the message to be decrypted according to a first private key component and a second public key component to obtain a first message and a second message; sending the first message and the second message to the second decryption terminal, so that the second decryption terminal decapsulates the first message and the second message according to a second private key component to obtain a third message, and sends the third message to the first decryption terminal; and the first decryption terminal decrypting the third message according to the first private key component to obtain a plaintext corresponding to the to-be-decrypted message. And the first decryption terminal and the second decryption terminal perform cooperative decryption, so that the problem that the private key of the user is singly stored on one decryption terminal and is easily illegally stolen by others is solved, and the security of user information is improved.

Description

technical field [0001] The present invention relates to the technical field of encryption and decryption, in particular to a decryption method and device. Background technique [0002] With the development of smart terminal technology, mobile Internet technology and cloud computing technology, more and more Internet applications have begun to migrate to smart mobile terminals, such as: Alipay, WeChat, online banking, etc. During the process, mobile terminals can be used to pay, shop, and send network messages anytime, anywhere. [0003] Due to the openness of the mobile terminal system, the key for decrypting files stored in the mobile terminal system is easily stolen. Therefore, if only relying on a single mobile terminal system to store the decryption key, the possibility of the decryption key being stolen is relatively high. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a decryption method and device to solve t...
