Secure multi-party computation privacy-protecting evaluation method based on scenes of internet of things

Abstract

The diversification of information acquisition terminals in an internet of things causes easy leakage of private information of a user, and the privacy of an evaluator and an evaluated person face serious threat, therefore, the protection of the privacy of evaluation parties becomes an urgent problem in online evaluation of the internet of things. In order to solve the problem, the invention provides a secure multi-party computation privacy-protecting evaluation method based on scenes of internet of things. The method has the beneficial effects that since the authentication of the identity of the evaluated person is carried out by using an identity authentication protocol and simultaneously the encryption and decryption processes of evaluation questionnaires are properly controlled, the security of evaluation is further ensured; since a high-efficiency secure multi-party computation is applied in the design of a secure evaluation system, the secure scoring and ranking of a trusted third party is not needed, the intervention of an evaluation mechanism is reduced, and the privacy of evaluation is guaranteed; and by use of the method for separated storage of evaluation data in an evaluation result data and an evaluated person database, on the basis of secure multi-party summing and scoring, the personal privacy of the evaluator and the evaluated person is protected.

Description

technical field [0001] The invention relates to an implementation method for protecting the privacy information of both an evaluator and an evaluator from being violated during network evaluation in the Internet of Things, and belongs to the cross field of the Internet of Things and information security technology. Background technique [0002] The Internet of Things is based on the computer Internet, through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing equipment, according to the agreed protocol, any item is connected to the Internet for information exchange. A network for intelligent identification, positioning, tracking, monitoring and management. The emergence of the Internet of Things is bringing concrete and profound changes to modern society, and its application fields involve all aspects of people's daily life. Therefore, in the future, information collection terminals such as RFID ...

Problems solved by technology

At the same time, each evaluator can read the total score value and final ranking of each evaluator from its corresponding RFID tag, but cannot extract the specific evaluation questionnaires of other evaluators, thereby protecting the evaluator's personal privacy
