IoT Security: Securing Connected Devices
Security protocols are used to ensure that data transmitted between devices in an IoT network is secure. These protocols provide a secure channel for data to travel through while preventing unauthorized access to the data. Security protocols for IoT networks involve encryption, authentication, and secure communication.
Encryption is used to protect data being transmitted over the network. It involves converting the data into a code that can only be read by authorized devices. Encryption algorithms are used to encrypt and decrypt the data.
Authentication is used to ensure that only authorized devices can access the network. Devices are authenticated using different methods, such as passwords, digital certificates, and biometric authentication.
Secure communication ensures that data is not tampered with during transmission. This involves using protocols such as Transport Layer Security (TLS) and Secure Sockets Layer (SSL).
Examples of security protocols for IoT include the IoT Security Protocol (IoTSP), Message Queuing Telemetry Transport (MQTT), and Constrained Application Protocol (CoAP). These protocols provide secure communication between devices in an IoT network.
