摘要
随着信息化技术的不断发展,云计算已经成为新一代产业和业务模式变革的焦点,云计算的虚拟化、多租户、弹性计算等特点对密码应用提出了更高的要求,除了租户化与服务化地提供密码资源并统一管理,提高密码运算速率也是重中之重。而数字签名技术作为密码技术的一种,在云平台和云上业务系统中应用广泛,随着应用业务量的迅速增长,为用户提供高速高效的、可靠且不间断的、按需分配并动态扩展的数字签名服务,实现安全设施资源的利用最大化,逐渐得到业界的认可和推崇。实现密码运算高速化的传统思路多是从芯片或板卡算力层面进行优化,周期和成本代价较高,迫切需要以相对低和易实现的技术路径实现安全密码服务的高性能,满足日益增长的用户数据安全需求。
With the continuous development of information technology,cloud computing becomes the focus of the new generation of industry and business model reform.The features of cloud computing,such as virtualization,multi-tenancy and elastic computing,put forward higher requirements for cryptographic applications.In addition to providing cryptographic resources and unified management in a tenant and service manner,improving the cryptographic operation rate is also a top priority.As a kind of cryptographic technology,digital signature technology is widely used in cloud platforms and cloud based business systems.With the rapid growth of application traffic,it provides users with high-speed,efficient,reliable,uninterrupted,on-demand distribution and dynamic expansion of digital signature services to maximize the utilization of security facilities resources,which is gradually recognized and approved by the industry.The traditional way to realize high-speed cryptographic operations is to optimize the computing power of chips or boards,which has high cycle and cost.It is urgent to achieve high performance of secure cryptographic services with relatively low and easy technical paths to meet the growing user data security needs.
