摘要:

无线体域网(WBAN)近年来获得了大量的研究关注,因为它们为远程健康监测和连续实时的患者护理提供了巨大的好处。然而,与任何无线通信一样,WBAN中的数据安全性是一个具有挑战性的设计问题。由于此类网络由放置在人体上的小型传感器组成,因此它们施加了资源和计算限制,从而使复杂和先进的加密算法的使用变得不可行。这就要求设计一个强大的密钥生成/管理方案的算法,这是合理的资源优化。本文提出了一个安全套件的WBAN,包括IAMKeys,一个独立的和自适应的密钥管理方案,以提高WBAN的安全性,和KEMESIS,一个密钥管理方案,在传感器之间的通信安全。这些方案的新颖性在于使用随机生成的密钥来加密在发送方和接收方独立生成的每个数据帧,从而消除了对任何密钥交换的需要。加密方案的简单性与密钥管理的适应性相结合使得方案简单而安全。通过性能分析验证了算法的有效性。

英文摘要:

Wireless Body Area Networks (WBANs) have gained a lot of research attention in recent years since they offer tremendous benefits for remote health monitoring and continuous, real-time patient care. However, as with any wireless communication, data security in WBANs is a challenging design issue. Since such networks consist of small sensors placed on the human body, they impose resource and computational restrictions, thereby making the use of sophisticated and advanced encryption algorithms infeasible. This calls for the design of algorithms with a robust key generation / management scheme, which are reasonably resource optimal. This paper presents a security suite for WBANs, comprised of IAMKeys, an independent and adaptive key management scheme for improving the security of WBANs, and KEMESIS, a key management scheme for security in inter-sensor communication. The novelty of these schemes lies in the use of a randomly generated key for encrypting each data frame that is generated independently at both the sender and the receiver, eliminating the need for any key exchange. The simplicity of the encryption scheme, combined with the adaptability in key management makes the schemes simple, yet secure. The proposed algorithms are validated by performance analysis.
