Data security and user privacy are two main security concerns in the cold-chain logistics system(CCLS).Many security issues exist in traditional CCLS,destroying data security and user *** digital signature can provide data verification and identity authentication based on the mathematical difficulty problem for logistics data sharing in *** paper first established a blockchain-enabled cold-chain logistics system(BCCLS)based on union blockchain technology,which can provide secure data sharing among different logistics nodes and guarantee logistics data security with the untampered blockchain ***,a lattice-based undeniable signature scheme is designed to strengthen the security of logistics data and user privacy against quantum *** scheme is based on the lattice assumption,which can provide anti-quantum security for BCCLS in the future quantum computer *** also establishes the undeniable mechanism that guarantees that the actual signer cannot deny a valid ***,security proof shows that this undeniable signature scheme is correct and safe,and an efficiency comparison shows that it is more efficient than other schemes in similar *** performance evaluations of transaction throughput and latency show that the proposed BCCLS is efficient and *** work can improve the security and efficiency of logistics data management and promote the reform and development of the logistics industry.
