Embodiment Construction

[0034] As mentioned in the background technology, the existing data transfer method is difficult to trace the source of the data and ensure the authenticity of the data, and thus cannot guarantee the security of the data, so the security of the data needs to be improved.

[0035] In order to solve the above problems, 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, and the received public key and the private key of the second user are used to The private key of the first user generated by the key generation device can generate a re-encryption key, and the entire public-private key pair and the re-encryption key are directly participated by the user, so the ownership of the user's key can be guaranteed, and data security can be further improved sex.

[0036] In order to make the above objects, features and beneficial ef...

Abstract

The invention discloses key generation equipment, a key management system, data processing equipment and a data transaction system. The key generation equipment comprises an encryption engine which isconfigured to generate a public and private key pair of a first user, store the public and private key pair to a memory, reads a private key of the first user and a public key of a second user in thememory, generates a re-encryption key, and sends the re-encryption key to a processor; the memory which is configured to store the public and private key pair of the first user generated by the encryption engine; the processor which is configured to receive the public key of the second user sent by a communication interface, sends the public key to the encryption engine, receives the re-encryption key generated by the encryption engine and sends the re-encryption key to the communication interface; and the communication interface which is configured to receive the public key of the second user, sends the public key to the processor and sends out the re-encryption key transmitted by the processor. Through adoption of the scheme, the data security can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a key generation device and a management system, a data processing device, and a data transaction 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, personal data in smart phones, important data generated by instruments, machining equipment generated processing data, etc. When data generated by said devices is stolen, lost or compromised, it is put at risk. Furthermore, 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, ...
