Embodiment Construction

[0030] As described in the background art, in the existing data transfer mode, it is difficult to avoid data leakage during the data transfer process, so the security of the data transfer needs to be improved.

[0031] In order to solve the above problems, in the embodiment of the present invention, the data processing device and the data collection device are seamlessly connected, and the data processing device has a built-in physically isolated encryption chip, and the collected data is encrypted and generated at the source of data collection. The re-encryption key can avoid the leakage of data and key, so it can improve the security of data transfer.

[0032] In order to make the above objects, features and beneficial effects of the embodiments of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] refer to figure 1 The structural diagram of the da...

Abstract

The invention relates to a data processing device and a transaction system, the data processing equipment is coupled with a data acquisition device and comprises a data collection device, an encryption chip, a data processing device and a transmission device, and the data collection device is used for collecting data acquired by the data acquisition device and transmitting the data to the encryption chip; an Encryption chip, generating a public and private key pair of the first user, encrypting the collected data by adopting the public key of the first user to generate ciphertext data, transmitting the ciphertext data to the data processing device, receiving a public key of a second user from the data processing device, generating a re-encryption key by adopting the private key of the first user and the public key of the second user, and transmitting the re-encryption key to the data processing device; The data processing device receives the public key, transmitted by the transmissiondevice, of the second user, transmits the public key to the encryption chip, receives the ciphertext data and the re-encryption key and transmits the ciphertext data and the re-encryption key to the transmission device; And the transmission device is used for transmitting the ciphertext data and the re-encrypted data to a network side. By adopting the scheme, the security of data flow can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to data processing equipment and a transaction system. Background technique [0002] With the continuous development of computer networks and smart devices, especially the rise of Internet of Things technology, various data transfers have been realized between data terminal equipment and server equipment, terminal equipment and terminal equipment. [0003] However, in the current data transfer process, the security of data transfer is often not guaranteed. Contents of the invention [0004] The technical problem solved by the embodiments of the present invention is how to improve the security of data flow. [0005] In order to solve the above technical problems, an embodiment of the present invention provides a data processing device, the data processing device is coupled with the data acquisition device and includes: a data collection device, an encryptio...
