At present, various types of illegal and criminal activities occur frequently with the use of false seals, it has caused huge economic losses and serious social harm, and how to effectively implement anti-counterfeiting of seal has become an important problem to be solved. Based on the analysis of the traditional anti-counterfeiting technology of seal and new anti-counterfeiting technology solution, this paper proposes an anti-counterfeiting method of seal based on domestic cryptography algorithm, and introduces the whole lifecycle management framework of seal based on domestic cryptography algorithm, key management system, chip seal issuance and verification process. It also analyzes the safety of its cryptography algorithm, business process and information. The method constructs an integrated security chain between the components of the system in chip seal issuance and verification process. It ensures the credibility of the participants and guarantees the security of the whole process of seal information storage, processing and transmission, which improves the efficiency of chip seal issuance and verification process. It can be widely applied to the large-scale issuance and mutual recognition of chip seals, realizing secure and convenient identification of chip seals.%当前,利用假印章进行各类违法犯罪的活动频繁出现,造成了巨大的经济损失和严重的社会危害,如何有效实现印章防伪已成为亟待解决的重要问题.文章在总结分析传统印章防伪技术及新型印章防伪技术的基础上,提出了一种基于国产密码算法的印章防伪方法,阐述了基于国产密码算法的印章全生命周期管理架构、密钥管理体系、芯片印章发行及验证过程,并分析了其密码算法、处理流程、业务信息等方面的安全性.该方法构建了芯片印章发行及验证过程中系统各组件间的完整安全链条,确保了参与主体的可信性,保障了印章信息存储、处理与传输的全程安全,提高了芯片印章发行及验证效率,可广泛应用于芯片印章的大规模发行和互认互通业务,能够安全便捷地鉴别芯片印章真伪.
