Embodiment 1
[0025] For the blockchain-based laboratory paper storage system, please refer to the attached figure 1 , including several upper computer modules 10, certificate storage modules 30 and associated modules 40, the upper computer module 10 is installed in the upper computer of the test equipment in the laboratory, and the upper computer module 10 includes an acquisition unit 11, a certificate storage unit 12, a storage unit 13 and the sharing unit 14, the acquisition unit 11 collects test equipment data and associated input data, the test equipment data is the state data of the experimental equipment collected periodically in the test, and the associated input data includes experimenters, test items, test parameters and time stamps, Acquisition unit 11 uses test equipment data and associated entry data association directory information as test data, directory information includes data ID, test equipment, test items and time stamp, data ID requests to association module 40 to obtai...
Embodiment 2
[0053] Based on the blockchain-based laboratory paper storage system, this embodiment proposes a new alternative technical solution for the acquisition of encrypted polynomials on the basis of the first embodiment. Please refer to the attached Figure 5 , when the sharing unit 14 obtains the encrypted polynomial, the following steps are performed: Step D01) Calculate the sample point distance of the unary polynomial of n sample points in the value pair group, and arrange the unary polynomial according to the ascending order of the sample point distance; Step D02) choose arbitrarily One of the unary polynomials is used as an encryption polynomial, and the order of the encryption polynomials is recorded as order s; Step D03) The sharing unit 14 sends the associated integer n, sequence number k and order s of the time-limited ciphertext to the association module 40 . Please refer to the attached Image 6 , when the association module 40 obtains the restored encrypted polynomial,...
Embodiment 3
[0064] Based on the blockchain-based laboratory paper storage system, this embodiment proposes a new alternative technical solution for the acquisition of encrypted polynomials on the basis of the second embodiment. Please refer to the attached Figure 7 , when the sharing unit 14 obtains the encrypted polynomial, perform the following steps: step F01) randomly generate a value pair (x0, y0), add the value pair (x0, y0) to the value pair group corresponding to serial number k; step F02) calculate all the values For the sample point distances of the univariate polynomials of n sample points in the group, arrange the univariate polynomials in ascending order according to the sample point distance; step F03) randomly select one of the univariate polynomials as the encryption polynomial, and record the order of the encryption polynomials as order s; step F04 ) sharing. The time-limited ciphertext associated value pair (x0, y0), integer n, serial number k and sequence s are encrypt...
