Logistics Information Privacy Protection Scheme Using Attribute Based Encryption

With the rapid development of the Internet of Things technology,the Logistics Internet of Things(LIOT)has become an indispensable pattern of modern logistics industry.The application of traceability systems,intelligent logistics distribution centers and other applications have deeply affected people's daily lives,but at the same time the problem of customer's parcel information leakage has also brought threats to people's lives.The logistics information in the logistics Io T environment still has the following threats:(1)The privacy of logistics information is difficult to guarantee.Traditional logistics privacy protection schemes tend to focus only on the private information of customers,while ignoring the privacy protection of complete logistics information.(2)The safety management of a large number of logistics workers is difficult.The access control of the internal staff of the logistics company is difficult to achieve.(3)The identity authentication of the customer is difficult to complete.A malicious customer may falsify their identity to receive a package.(4)It is difficult to trace the source of logistics transaction information.The logistics chain contains a large amount of logistics transaction information.Once a package dispute arises,it is difficult to trace the traceability of logistics information.This paper studies the privacy protection of logistics information aiming at the practical logistics transactions scenarios.Firstly,we propose a logistics information privacy protection scheme using attribute based encryption to provide privacy protection of both personal information and logistics information.We construct the system model,adversary model and security goals according to the security requirements of LIOT.In order to achieve the safety management of a large number of couriers,we adopted the CP-ABE mechanism,so that different couriers can only decrypt part of the logistics information according to their own attributes.The location-based access control of the courier is realized through the location based cryptography.In addition,we utilize the public key encryption and digital signature to achieve the confidentiality of private information and the verifiability of customer.Secondly,we design a blockchain based logistics information privacy protection scheme to ensure traceability of logistics transactions.We propose new security goals according to the system model and adversary model of this scheme.We adopt blockchain technology and store all logistics transaction information on the blockchain.With ensuring the confidential-ity of logistics information,the open consensus of the blockchain system make the logistics transaction records untampered and traceable.The security analysis results show logistics information privacy protection scheme using attribute based encryption can satisfy all the security requirements of LIOT.In addition,the blockchain based logistics transaction scheme can achieve the traceability of logistics transaction information.The performance analysis results show that the two schemes proposed in this paper are both efficient in actual logistics transaction scenarios.
