Description
Technical Field
The invention relates to the field of quantum secret communication, in particular to a light-weight IBC bidirectional identity authentication system and method based on a quantum key.
Background
The quantum has the inherent properties of inseparable, unmeasurable and unclonable due to the mechanical properties, and has great application value in the field of transmission secret communication. Quantum Key Distribution (QKD) is an important branch in quantum secure communications technology. QKD is the establishment of a secure channel between two users, sharing quantum keys through single photon transmission/reception and key agreement. Such a secure channel necessarily involves an authentication process for both parties.
The traditional communication parties commonly adopt a PKI authentication system and an IBC authentication system. PKI refers to a ubiquitous security infrastructure that implements and provides security services with the concept and technology of public keys. In PKI, the CA authentication center binds the identity information (user name, id card number, etc.) of the user with its public key, so that the function of identity authentication in the network environment can be realized. PKI provides a range of applications (encryption, decryption, signing and verification, etc.) that support public key cryptography. The security service functions which can be supported by the system mainly comprise: identity authentication, data integrity verification, data confidentiality, non-repudiation, and the like. The PKI aims to provide comprehensive security services for various network applications by managing the generation and storage of a secret key, the security of a public key certificate and the like by means of the theoretical basis of public key cryptography, so that the authentication of the identity of a user, the confidentiality, the integrity, the validity and the like of data can be effectively realized.
The IBC authentication is different from PKI authentication scheme, the key idea of the IBC authentication technology is that the certificate is not used in the system any more, but the authentication can be completed through three keys, namely a system master key, a user public key and a private key. The public key of the user is generated by extracting the identity information of the user, and the private key can be calculated by a trusted third party called a private key generator and transmitted to the user through a secure channel. The identity authentication idea realizes the binding of the public key and the identity of the authentication entity, so that the authentication of both sides can be completed without exchanging the public key.
PKI authentication requires a large number of CA certificate exchanges, the key management is complex, and the expenditure on calculation and communication resources is large; the public and private key pairs authenticated by the IBC are stored in the private key generator, so that the problem of key escrow exists, and once the private key generator is cracked, the leakage of all keys can be caused; meanwhile, the IBC algorithm is based on bilinear pair operation, the operation complexity is high, and the existing algorithm is not efficient enough. Therefore, it is important to design a more flexible, secure, and lightweight identity authentication process for the limitations of PKI authentication and IBC authentication.
