Abstract: At present, many digital certificate domains coexist under the conditions of different cryptographic algorithms, service domains and technical specifications, which leads to the problem of correlation between time and space verification of electronic signatures based on the construction of digital certificate system, and becomes a difficult problem that hinders the comprehensive promotion and application of electronic signatures. Facing this dilemma, an electronic signature verification platform design scheme is proposed based on block chain technology, which recorded electronic signature transaction data into the chain through alliance chain, a distributed and decentralized electronic signature verification service platform is constructed, which provides the secure, reliable, efficient and convenient verification services for electronic signatures to solve the timespace independence verification of electronic signatures and support comprehensive promotion of the electronic signatures in e-government, e-commerce and other public applications.

摘要： 前在密码算法体制、服务领域、技术规范差异化条件下多种数字证书域并存，引发基于数字证书系统建设的电子签章时空验证相关性问题，成为阻碍电子签章全面推广应用的一个难题.面对这一困境，基于区块链技术，提出一种电子签章验证平台设计方案，通过联盟链的方式记录电子签章交易数据入链，构建分布式、去中心化的电子签章验证服务平台，为电子签章提供安全可靠、高效便捷的验证服务，解决电子签章的时空无关性验证，支持电子签章在电子政务、电子商务及其他公共应用的全面推广.
