LAKEE:一种用于功率受限设备的轻量级认证密钥交换协议

LAKEE: A Lightweight Authenticated Key Exchange Protocol for Power Constrained Devices

Seyedsina Nabavirazavi, S. Sitharama Iyengar

摘要:

物联网网络的快速发展导致了为其设计有效安全功能的研究趋势。由于物联网设备的功率受限性质,安全功能应尽可能保持轻量级。目前,大多数物联网网络流量都是未加密的。智能设备未加密数据的泄露可能会带来隐私泄露的巨大成本。为了使安全信道具有加密流量,网络中的两个端点必须相互验证并计算短期密钥。然后,它们可以通过经过身份验证的安全信道进行通信。这个过程被称为认证密钥交换(AKE)。虽然数据报传输层安全(DTLS)为物联网网络提供了一个AKE协议,但研究已经提出了更有效和更具体的替代方案。本文介绍了LAKEE,一个简单的,轻量级的物联网AKE协议。我们的协议采用椭圆曲线密码产生一个短期的会话密钥。它减少了其替代方案的通信和计算开销,同时保持或提高其安全强度。我们的协议的简单性和低开销,使它适合网络的受限设备。

英文摘要:

The rapid development of IoT networks has led to a research trend in designing effective security features for them. Due to the power-constrained nature of IoT devices, the security features should remain as lightweight as possible. Currently, most of the IoT network traffic is unencrypted. The leakage of smart devices' unencrypted data can come with the significant cost of a privacy breach. To have a secure channel with encrypted traffic, two endpoints in a network have to authenticate each other and calculate a short-term key. They can then communicate through an authenticated and secure channel. This process is referred to as authenticated key exchange (AKE). Although Datagram Transport Layer Security (DTLS) offers an AKE protocol for IoT networks, research has proposed more efficient and case-specific alternatives. This paper presents LAKEE, a straightforward, lightweight AKE protocol for IoT networks. Our protocol employs elliptic curve cryptography for generating a short-term session key. It reduces the communication and computational overhead of its alternatives while maintaining or improving their security strength. The simplicity and low overhead of our protocol make it a fit for a network of constrained devices.
