In the ubiquitous networks, mobile nodes can obtain roaming service that enables them to get access to the services extended by their home networks in the field of foreign network. To provide secure and anonymous communication for legal mobile users in roaming services, there should be a mutual authentication between mobile user and foreign agent with the help of home agent. There are many roaming authentication schemes which have been proposed; however, with the progress of quantum computation, quantum attack poses security threats to many traditional public key cryptography-based authentication schemes; thus, antiquantum attack roaming authentication schemes need to be investigated. On account of the limitation of computational resources for mobile nodes, a lightweight anonymous and antiquantum authentication schemes need to be developed to enable mobile nodes to roam across multiple service domains securely and seamlessly. In consideration of the advantages of lattice in antiquantum, an NTRU-based authentication scheme with provable security and conditional privacy preservation is proposed to remedy these security weaknesses. Compared with the existing scheme, the proposed scheme not only improves efficiency but also can resist the quantum attack.

具有匿名性的无处不在网络中基于格的漫游服务认证方案

在无处不在的网络中,移动节点可以获得漫游服务,该漫游服务使它们能够访问在外部网络领域中由其本地网络扩展的服务。为了在漫游服务中为合法的移动用户提供安全和匿名的通信,在本地代理的帮助下,移动用户和外部代理之间应进行相互身份验证。已经提出了许多漫游认证方案。但是,随着量子计算的发展,量子攻击对许多传统的基于公钥密码学的认证方案构成了安全威胁。因此,需要研究反量子攻击漫游认证方案。由于移动节点的计算资源有限,需要开发轻量级的匿名和反量子身份验证方案,以使移动节点能够安全,无缝地跨多个服务域漫游。考虑到晶格在反量子中的优势,提出了一种基于NTRU的具有可证明的安全性和有条件的隐私保护的身份验证方案,以弥补这些安全性缺陷。与现有方案相比,该方案不仅提高了效率,而且可以抵抗量子攻击。
