Abstract

The rapid and exponential deployment of Internet of things (IoT) that is connected to the Internet has created an internet of vulnerabilities. The successful deployment in different domains of IoT depends on securing the communications in the IoT ecosystem. With the limited resources that these IoT devices have, it's a very challenging task to provide the necessary security measures for such devices. Many application protocols are used in IoT ecosystem. Constrained Application Protocol (CoAP), however, is one of the most used protocols in the e-health system. CoAP in itself does not provide any security measures. In this paper, we propose an enhancement to CoAP to make it provide such necessary security element. We propose a security mechanism to support Authentication and Access Control scheme for CoAP (AAC-CoAP). The results show that the proposed AC enhancement improved the security of IoT devices. In addition, it shows that the CPU calculation time as well as execution time have improved significantly.

基于coap的物联网安全认证与访问控制方案
连接到互联网的物联网(IoT)的快速和指数级部署创造了一个漏洞的互联网。在物联网不同领域的成功部署取决于物联网生态系统中的通信安全。由于这些物联网设备拥有的资源有限,为这些设备提供必要的安全措施是一项非常具有挑战性的任务。物联网生态系统中使用了许多应用协议。约束应用协议(CoAP)是电子医疗系统中使用最多的协议之一。CoAP本身不提供任何安全措施。在本文中,我们提出了对CoAP的增强,使其提供必要的安全元素。我们提出了一种支持CoAP认证和访问控制方案的安全机制(AAC-CoAP)。结果表明,所提出的交流增强提高了物联网设备的安全性。此外,CPU计算时间和执行时间都有了明显的改善。
