Attribute-Based Authentication Scheme from Partial Encryption for Lattice with Short Key

Wireless network is the basis of the Internet of things and theintelligent vehicle Internet. Due to the complexity of the Internet of things andintelligent vehicle Internet environment, the nodes of the Internet of thingsand the intelligent vehicle Internet are more vulnerable to malicious destructionand attacks. Most of the proposed authentication and key agreementprotocols for wireless networks are based on traditional cryptosystems such aslarge integer decomposition and elliptic curves. With the rapid developmentof quantum computing, these authentication protocols based on traditionalcryptography will be more and more threatened, so it is necessary to designsome authentication and key agreement protocols that can resist quantumattacks. In this paper, an anti-quantum authentication scheme for wirelessnetworks based on lattice cryptosystem is constructed. In the attribute-basedauthentication scheme, the length of the authenticated public-private keypair depends on the maximum order and complexity of the formula in thealgorithm. In the attribute-based authentication scheme, there is a certaincorrelation between the authenticated data and the attribute value of theuser in the scheme. We show that the attribute-based authentication schemegives an attribute-based with smaller public-private key pairs. The securityof the attribute-based authentication scheme is based on the sub-exponentialhard problem of the LWE (Learning With Errors). The Q-poly made bythe adversary in the scheme, and our attribute-based authentication schemeguarantees that private data about user attributes and ciphertext cannot beobtained by malicious attackers.
