Abstract: Being strictly and scientifically proven, cryptography is the fundamental technology of cyberspace security. A spiral development trend among cryptography, its serving objects and the technological development is presenting. With the rapid development of cyberspace technology and the inherent drive of cryptography attack and defense, the connotation and extension of cryptography have undergone major changes. Cryptography is not only the core technology of cyberspace security, but also the cornerstone of trust in the digital economy security..Faced with the severe situation of cyberspace security and the development trend of the digital economy, cryptography technology shall closely follow the applications to promote its innovation, cryptography industry shall be optimized to strengthen the cryptography supply, and cryptography evaluation shall be standardized to protect the cryptography application security. As a special strategic resource, cryptography cannot be bought from others, and it cannot be fully trusted even bought from others. It is of great significance to rely on independent innovation of our own cryptography. And the issues that discipline level of cryptography is set too deep, and high-end compound cryptography talents are of shortage shall be resolved as soon as possible.

Key words: commercial cryptography, cryptography application, industry supply, cryptography discipline, cryptography evaluation

摘要： 密码是经严格科学证明的网络空间安全的根本性核心技术。密码与其服务对象和科技发展呈扭结螺旋式发展态势。随着网络空间技术飞速发展和密码攻防对抗的内在驱动，密码的内涵外延发生了重大变化，密码不仅是维护网络空间安全的核心技术，还是构建数字经济产权纽带的核心支撑。面对网络空间安全严峻形势，适应数字经济发展大势，密码必须紧贴应用促创新，做优产业强供给，规范测评保安全。密码作为特殊战略资源，买不来淘不来，买来淘来也不敢用，必须靠自主创新，必须加快解决密码学科层级设置过低、密码高端和复合型人才紧缺问题。
