Embodiment 1

[0058] Such as figure 2 As shown, a kind of agricultural product traceability information security solution using block chain technology of the present invention includes:

[0059] Step S101: Improve the consensus mechanism to obtain an improved consensus mechanism. The improved consensus mechanism is: when all physical terminals hold blocks to be submitted for verification, in order to maximize their own benefits, no physical terminal can change its own The verification results of blocks generated by other entity terminals.

[0060] The improved consensus mechanism includes:

[0061] If the calculation time of this round has not ended, for the earliest A i ∈A, and let u i (S i1 ,…S ij ,...,S in )=n, then choose A i The blocks generated by packaging are used as the current round of consensus blocks;

[0062] If the calculation time of this round has ended, such that n>u i (S i1 ,…S ij ,...,S in )> u j (S j1 ,…S ji ,...,S jn ), then select A i The blocks gen...

Embodiment 2

[0092] Such as image 3 As shown, another agricultural product traceability information security solution using blockchain technology of the present invention includes:

[0093] Step S201: Obtain a problem model through problem modeling.

[0094] The security threats faced by the agricultural product traceability information system have the following characteristics:

[0095] (1) The attack source is unlimited, each attacker comes individually, independent of each other, and the attack flow is stable, regardless of the peak period or idle period;

[0096] (2) The arrival of the attacker conforms to the Poisson distribution with parameter λ, where λ is the average value of the arrival attack per unit time;

[0097] (3) The tampering of traceability information caused by each attack obeys the parameter m The negative exponential distribution of ;

[0098] (4) The time interval between the arrival of each attack and the damage caused are independent of each other.

[0099] S...

Abstract

The invention relates to the technical field of traceability information security of agricultural products, in particular to a traceability information security solution of agricultural products adopting block chain technology. The method comprises the following steps: an improved consensus mechanism being obtained, wherein the improved consensus mechanism is that when all entity terminals hold blocks to be submitted for verification, in order to maximize their own benefits, no entity terminal can change the verification result of blocks generated by packaging other entity terminals; conducting multi-level traceability information verification; using multi-private-key rules to control access rights; through the improved consensus mechanism, multi-level traceability information verificationand multi-private key rules for access control, distributed bookkeeping being realized. The invention solves the data storage safety problem existing in the agricultural product traceability system.

Description

technical field [0001] The present invention relates to the technical field of traceability information security of agricultural products, in particular to an agricultural product traceability information security solution using block chain technology applied to an agricultural product traceability system. Background technique [0002] The construction of agricultural product traceability system is an important means to manage and control the safety of agricultural products. Such systems often use RFID and two-dimensional codes as traceability labels, which have the advantages of low cost and fast reading and writing, but face many threats, including from the physical environment, Software and hardware failures, misoperation or misoperation, lack of management, malicious codes and viruses, authority management loopholes, hacker attack techniques, internal leaks, illegal tampering and denial, etc. These threats have caused great damage to the integrity, reliability and availa...
