摘要: 在医疗无线体域网信息传输中,基于生物特征和可信第三方公钥基础设施等认证机制存在身份漏报、误报和部署成本高的缺陷。为此,在分析医疗无线体域网认证机制的安全及性能需求的基础上,将椭圆曲线密码体制加密与签名算法引入现有基于挑战应答的轻量认证协议,基于体验、性能、安全和成本的均衡考虑,提出一种端到端的轻量认证协议。理论证明和实验结果表明,该协议具备端到端、轻量、互认证、不可链接和低成本等优势,是一种优选的医疗无线体域网备选认证协议。

Abstract: For the information transmission in medical Wireless Body Area Network(WBAN),authentication mechanisms based on biological features and public key infrastructure with trusted third party have drawbacks of identity false negative,false positive and high deployment cost.On the basis of analyzing security and performance requirement of authentication mechanism for medical WBAN,Ecliptic Curve Cryptosystem(ECC) encryption and signature algorithm is introduced into existing lightweight authentication protocols based on challenge and response.Based on the best trade-off perspective among experience,performance,security and cost,an end-to-end lightweight authentication protocol is proposed.Theory proof and experiment results indicate that the protocol is provided with superiority of end-to-end,light weight,mutuality,unlinkability,low cost and so on.It is an excellent candidate to medical WBAN.

Key words: Wireless Body Area Network(WBAN), medical application, authentication protocol, resource constraint, end-to-end authentication
