Problems solved by technology

[0003] At present, the sender usually uses a single private key to encrypt data, and correspondingly, the receiver uses the public key corresponding to the private key to decrypt the data, that is, the whole process uses a pair of keys (that is, the private key and the public key of the sender), so its Security needs to be improved
Moreover, the commonly used encryption algorithms mostly use hash functions and redundant functions, both of which require a relatively large amount of calculation, so the calculation efficiency and transmission efficiency are reduced

Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0059] At present, at present, the sending end usually uses a single private key to encrypt data, and correspondingly, the receiving end uses the public key corresponding to the private key to decrypt the data, that is, the whole process uses a pair of keys (that is, the private key and the public key of the sending end), Therefore, its security needs to be improved. To this end, the present application provides a data sending method and device, a data receiving method and device, w...

Abstract

The data sending method disclosed in the present application is applied to the sending end, which can use double private keys and an elliptic curve encryption algorithm to sign-encrypt the data to be sent, thereby improving data security. Among them, the key of the elliptic curve encryption algorithm is shorter and the calculation amount of signcryption is smaller, so the efficiency of signcryption and data transmission can be improved; the flexibility and security are also higher. Correspondingly, the data sending device, data receiving method and device provided in the present application also have the above technical effects.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a data sending method and device, and a data receiving method and device. Background technique [0002] In the prior art, in order to improve data security, when sending data, the sending end encrypts the data first, and then sends the encrypted data to the receiving end. Among them, when the sending end encrypts data, it often uses a key pair to encrypt data, such as: the sending end encrypts data with a private key, and the receiving end decrypts data with a corresponding public key. [0003] At present, the sender usually uses a single private key to encrypt data, and correspondingly, the receiver uses the public key corresponding to the private key to decrypt the data, that is, the whole process uses a pair of keys (that is, the private key and the public key of the sender), so its Security needs to be improved. Moreover, commonly used encryption algo...
