Introduction to SM9 Identity Cipher Algorithm

SM9 algorithm is an identity-based cryptographic algorithm (“IBC” for short), which consists of three parts: digital signature algorithm, identity encryption algorithm, and key agreement protocol. Compared with traditional cryptosystems, the biggest advantage of SM9 cryptosystems is that no certificates are required. , easy to use, easy to manage, low total cost of ownership. The SM9 algorithm is widely used and can realize various data encryption, identity authentication and other security services; due to its ease of use and high security, it is very suitable for secure communication between massive devices. Data security in the fields of the Internet, Internet of Things, and Internet of Vehicles has unique advantages.

SM9 Identification Cryptosystem Encryption and Decryption Strategy

Using the security solution based on the national secret SM9 identification and password technology, it supports a large number of users without the need to issue and manage digital certificates, which greatly saves management costs; solves various security issues such as identity authentication, data security, transmission security, and access control, and can also support Voice and video data protection.
