Post quantum identity authentication mechanism in blockchain
Peng Duan, Bo Zhou · 2022
The blockchain technology has developed rapidly in recent years and has been widely used in all walks of life. However, most of the authentication systems adopted by the current blockchain technology are public key infrastructure based on large integer decomposition or discrete logarithm difficulties, and these cryptosystems are not secure in the quantum environment. Therefore, this paper considers an identity based post quantum authentication system applicable to the blockchain, which provides anti quantum protection and eliminates the dependence on public key certificates. Under the control of the supervision node, the authentication system has the key revocation function.
