可能您想问的是Transmission Control Protocol,简称TCP。
TCP(Transmission Control Protocol)即传输控制协议,是一种面向连接的、可靠的、基于字节流的传输层通信协议。它在网络通信中扮演着重要的角色,主要用于在互联网上的不同计算机之间可靠地传输数据。TCP协议提供了许多功能,如数据重传机制、流量控制、拥塞控制等,确保数据的可靠传输。TCP协议通过三次握手建立连接,四次挥手释放连接,保证了数据传输的可靠性。

RESTful IoT Authentication protocol COAP
The RESTful IoT Authentication protocol COAP (Constrained Application Protocol) is a protocol used to authenticate devices and clients in IoT (Internet of Things) systems. It is based on the principles of REST (Representational State Transfer) and is specifically designed for use in resource-constrained environments.
COAP allows devices and clients to communicate securely over the internet by using lightweight cryptographic techniques. It uses DTLS (Datagram Transport Layer Security) to provide confidentiality, integrity, and authentication of messages exchanged between devices and clients. The protocol also includes support for token-based authentication, which helps to prevent unauthorized access to resources.
In addition to authentication, COAP can also be used to monitor and control IoT devices. It supports a range of HTTP-like methods, including GET, POST, PUT, and DELETE, which can be used to request or update resource representations.
Overall, COAP provides a secure and efficient way to authenticate devices and clients in IoT systems, while also enabling communication and control between them.
