The medical data produced from various sensors of sensitive information so there is a need to secure them through security solutions. At present, many security solutions are available in the market to secure the medical data. Transport layer security (TLS) is designed to transfer the client from the client to the server in a more secure manner. The major advantage of using TLS is it will not lose any data while transferring the message from client to server. Datagram transport layer security (DTLS) is designed specifically to use in constrained networks. The DTLS protocol consists of major components like base protocol, record layer, and handshake protocol. The main disadvantage of DTLS is the attacker can send multiple Hello messages to the server. This can cause an attack against the server and this attack encourages a new connection between the client and server and also it increases required bandwidth and resources for every message. The main objective of the proposed work is to use the constrained application protocol (CoAP) with DTLS in place of user datagram protocol (UDP) for the secure transmission of data. To evaluate the efficiency of the system, the packet loss ratio, data transmission time, and handshake time are calculated.

物联网安全医疗数据传输模型的增强型约束应用协议

从敏感信息的各种传感器产生的医疗数据，因此需要通过安全解决方案来保护它们。目前，市场上有许多安全解决方案来保护医疗数据。传输层安全 (TLS) 旨在以更安全的方式将客户端从客户端传输到服务器。使用 TLS 的主要优点是在将消息从客户端传输到服务器时不会丢失任何数据。数据报传输层安全 (DTLS) 专为在受限网络中使用而设计。DTLS 协议由基本协议、记录层和握手协议等主要组件组成。DTLS 的主要缺点是攻击者可以向服务器发送多个 Hello 消息。这可能会导致对服务器的攻击，这种攻击会鼓励客户端和服务器之间建立新的连接，并且还会增加每条消息所需的带宽和资源。拟议工作的主要目标是使用带有 DTLS 的约束应用协议 (CoAP) 代替用户数据报协议 (UDP) 来安全传输数据。为了评估系统的效率，计算丢包率、数据传输时间和握手时间。
