Abstract
The work aims to improve the authenticity and integrity of data in agricultural product traceability system by introducing digital signature technology, to solve the key management and data security problems in food traceability and ensure the non-tampering and verifiability of agricultural product information. A digital signature system based on SM2 collaborative signature algorithm was designed. This system combined digital signature and anti-counterfeiting code technology to improve the security of private key of traceability information. By designing the two-party collaborative signature scheme and combining it seamlessly with the existing traceability system, digital signature generation and verification experiments were carried out respectively to ensure the validity and security of the signature. The experimental results showed that after 400 integrity function tests, the signature generation rate and verification pass rate both reached 100%. Through security test analysis, this collaborative signature scheme significantly improved the security of digital signature at reasonable cost, effectively prevented data tampering, and ensured the integrity and reliability of information. The SM2-based collaborative signature scheme can effectively improve data security in food traceability system, ensure data tamper-proof and credibility and has high practical value, especially suitable for information construction in agricultural products field, low security cost, and wide promotion value.
