Embodiment Construction

[0031] As mentioned in the background art, the existing data transfer methods cannot guarantee the security of data, so the security of data needs to be improved. In addition, the existing data transfer system is difficult to trace the source of the data and ensure the authenticity of the data.

[0032]To solve the above problem, in the embodiment of the present invention, a key generation device is used to generate a public-private key pair of the first user, wherein the public-private key pair includes a public key and a private key. When generating the re-encryption key, it is verified whether the received public key of the second user comes from a preset network node, thereby ensuring the generation of a secure re-encryption key. When the re-encryption key is sent externally, verify whether the generated re-encryption key comes from the encryption engine, which can prevent the preset network node from using the wrong re-encryption key, thereby improving data security.

Abstract

A key generation device, data processing equipment, and data transfer system, the key generation device includes: an encryption engine configured to generate a public-private key pair of a first user, store it in a storage unit, and receive a key pair sent by a verification unit The public key of the second user generates a re-encryption key using the public key of the second user and the private key of the first user, and sends it to the verification unit; the storage unit is configured to store the public and private keys of the first user Yes; the verification unit is configured to send the public key of the second user to the encryption engine when verifying that the public key of the second user comes from a preset network node; and when verifying that the received When the re-encryption key comes from the encryption engine, send the re-encryption key to the preset network node. Adopting the above solution can improve data security.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a key generation device, a data processing device, and a data transfer system. Background technique [0002] With the rapid development of communication technology, more and more data will be generated during the use of various devices, such as vehicle condition information recorded by driving computer, relevant information in smart phones, important data generated by instruments and meters, machining equipment generated processing data, etc. When data generated by said device is stolen, lost or compromised, it is put at risk. In addition, the source of the data cannot be traced, and the authenticity and security of the data cannot be guaranteed. Contents of the invention [0003] The technical problem solved by the embodiments of the present invention is how to improve data security. [0004] In order to solve the above technical problems, an embodim...
