Transport Layer Security
TLS is a commonly-used protocol for providing communications privacy and managing the
security of message transmission, allowing the system to communicate with other remote
parties and connect to the HTTPS URL for provisioning in a way that is designed to prevent
eavesdropping and tampering.
TLS protocol is composed of two layers: TLS Record Protocol and TLS Handshake Protocol. The
TLS Record Protocol completes the actual data transmission and ensures the integrity and
privacy of the data. The TLS Handshake Protocol allows the server and client to authenticate
each other and negotiate an encryption algorithm and cryptographic keys before data is
exchanged.
