Transport Layer Security (TLS)
Transport Layer Protocol (TLS) is a commonly used protocol for ensuring communications privacy and
managing the security of the message transmission. When secured by the TLS protocol, the device can
transmit the data and communicate safely.
The TLS protocol includes two protocol groups: the TLS handshake protocol and the TLS record protocol.
The TLS handshake protocol allows the server and the client to authenticate with each other before
negotiating about the data, the encryption algorithms and the encrypted keys. The TLS Record Protocol
completes the actual data transmission and ensures the data integrity and confidentiality. The TLS protocol
uses an asymmetric encryption algorithm to exchange keys, a symmetric encryption algorithm to ensure
data confidentiality, and the MAC algorithms to ensure data integrity.
