摘　　要：目前,近场通信技术(NFC)被广泛应用在移动支付、公交卡、门禁系统、电子标签等各个方面。为了解决NFC系统安全性问题,提出一种新的基于超椭圆曲线密码体制的NFC轻量级认证协议。与现有协议相比,新协议提供了双向认证服务,简化了秘钥管理,为认证各方提供了不可否认性特性。同时,新协议对认证过程和HECC中的标量乘运算也做了相应简化。HECC具有高安全性、低有限域的特点,适合应用于NFC系统中,在提供安全性的同时,降低对CPU计算能力的要求。分析表明,新协议达到了NFC系统的高安全性和高效率要求。Nowadays, NFC（Near Field Communication） is widely applied in many fields including mobile payment, bus card, access control system, electronic label and so on. In order to solve the security problem of NFC system, a novel NFC lightweight authentication protocol based on the hyper elliptic curve cryptosystem is proposed. Compared with the existing protocols, this novel protocol could provide mutual-authentication services, simplify key management, and furnish non-repudiation features for authenticated members. Meanwhile, this novel protocol also makes corresponding simplification of the authentication process and the scalar multiplication in HECC. HECC is characterized with high security and low finite field suitable for NFC system, and could reduce the requirements for the calculation capability of CPU while improving the security. Analysis indicates that this novel protocol could satisfy the requirements of high security and high efficiency by the NFC system.
