Features: This book introduces the CPK (Combination Public Key) algorithm for implementing identity authentication. The CPK algorithm achieves the scalability of public-private key pairs through a combination method, constructing a large public key space (e.g., 10) with minimal resources (e.g., 60KB). It binds identifiers and public keys through a mapping method. The book presents a multi-identifier domain and multi-scope real-name authentication system implemented on the CPKbufft—chip, which no longer requires third-party verification or remote or external device support for on-the-spot validation, and the verification module can be generalized and popularized. The book illustrates the CPK identity authentication algorithm with concrete examples, demonstrating its application in identifying authentication for email addresses, mobile phone numbers, accounts, seals, IP addresses, communication tags, software tags, certificates, and product names. Identity authentication is a critical issue in establishing order and building trustworthy systems in the information society, impacting trustworthy transactions, communication, computing, and logistics. It also provides a powerful means of identification for effective management of the information world, combating spam, and online forensics. This book is suitable for researchers, developers, and managers in the field of information security, with the hope of helping to establish a new security perspective.
