CPK refers to the actual processing capacity of the process in a controlled state (stable state) within a certain period of time. It is the inherent capability of the process, or it is the ability of the process to ensure quality. ?

It refers to the comprehensive process of five basic quality factors such as operators, machines, raw materials, process methods and production environment, which is the production process of product quality. Product quality is the comprehensive performance of the various quality factors in the process. For any production process, product quality always exists dispersedly. If the process capability is higher, the dispersion of product quality characteristic values ??will be smaller; if the process capability is lower, the dispersion of product quality characteristic values ??will be greater.

What does cpk mean?

CPK is the abbreviation of "Combined Public Key" in the field of information security. Its Chinese name is combined public key. It is an encryption algorithm that uses a small resources to generate large-scale keys, creating conditions for chip-based and agent-based authentication systems.

CPK key function

CPK is a combined public key system that combines key production and key management to achieve digital signatures and key exchanges, which can meet the needs of ultra-large Identification identification, entity identification, and data confidentiality requirements in large-scale information networks and non-information networks (including the Internet of Things).
