Logistics privacy protection system based on ciphertext policy attribute-based key encapsulation

Abstract

The invention relates to a logistics privacy protection system based on ciphertext policy attribute-based key encapsulation. The logistics privacy protection system comprises a trusted key generation mechanism, a logistics company management end server, n handheld mobile devices and user mobile devices, app is arranged on the user mobile device and the handheld mobile device; the n handheld mobile devices are respectively communicated with the logistics company management end server and the credible key generation mechanism, the user mobile device is respectively communicated with the credible key generation mechanism and the logistics company management end server, and the logistics company management end server is communicated with the credible key generation mechanism. The user mobile device also communicates with the nth handheld mobile device. According to the system, a new logistics privacy protection system is provided by combining CP-ABKE, an identity verification technology and a two-dimensional code technology, and an attribute-based information access authority control mechanism is designed by combining hierarchical encryption and a two-dimensional code scanning decryption technology, so that internal user information protection is realized.

Description

technical field [0001] The invention proposes a logistics privacy protection system based on Ciphertext Policy-Attribute Based Key Encapsulation (CP-ABKE, Ciphertext Policy-Attribute Based Key Encapsulation), which belongs to the field of logistics information security. Background technique [0002] According to the statistics of the State Post Bureau, in 2020, the cumulative business volume of national logistics service enterprises will be 83.36 billion, a year-on-year increase of 31.2%; the cumulative business income will be 879.54 billion yuan, a year-on-year increase of 17.3%. Among them, the cumulative volume of intra-city business was 12.17 billion, a year-on-year increase of 10.2%; the cumulative volume of non-local business was 69.36 billion, a year-on-year increase of 35.9%; the cumulative international / Hong Kong, Macao and Taiwan business volume was 1.84 billion, a year-on-year increase of 27.7%. However, in recent years, incidents of logistics companies leaking cu...
