摘　　要：针对无线体域网(WBAN)应用中人们关注的病患个人敏感数据在传输过程中容易受到攻击的安全问题,提出一种结合随机网络编码和椭圆曲线密码学(ECC)的安全签名方案。该方案首先在网络中引入随机网络编码建立多播网络模型,增加相同传输次数下的数据信息量;通过采用ECC算法对信息进行签名,保障病患相关生理信息的通信安全。该方案共有三个阶段,即创建、签名和验证阶段。理论证明了该方案是安全的,能够有效地对信息进行污染验证,并确定受攻击节点的位置。Security challenges in wireless body area networks （WBAN） have been paid unprecedented at- tention for the vulnerable of patient＇s personal sensitive data. In order to address prevalent security con- cerns ,a secure signature scheme based on network coding and elliptic curve cryptography（ECC） algorithm is proposed. The scheme firstly introduces network coding to establish a muhieast model in WBAN. The en- ergy efficiency of the network increases as more volume of data will be transmitted to the sink with the same number of transmissions. Through signing the packets by utilizing ECC algorithm, secure communication of patient-related physiological data is possible in hostile environments. The scheme includes three phases, i. e. , setup, signature and verification. Data simulation proves that the scheme is secure, simultaneously pro- vides authentication and detects malicious nodes that intentionally corrupt content on the network.
