| Popis: | 106 In recent years, many large-scale integrated projects have been launched, a large and complex integrated project document contains multiple departments responsible for different domians, when the project is running, all departments need to sign the professional domains involved. In order to solve the trivial and complicated signing of each department in the large-scale project document, and ensuring that the entire document is signed, will not be tampered with, so the study was proposed. Proposed the Multiple Group signature with Threshold authorization and Document Decomposition, through document segmentation the departments are responsible for signing the responsibility. Each department signs the document with different Thresholds authorization of Elliptic Curves Digital Signatures. The final output of the organization is a multi-group signature with multiple Elliptic Curves Digital Signatures. The seal can only allow external receivers to verify that signature is from the organization, and receivers is impossible to know who is signed by those departments.This study comply with Federal Information Processing Standards (FIPS) requirements of the U.S. federal government three security provisions for digital signatures: Authentication, Integrity, and Non-repudiation. |
