The HTTP communication can be protected using TLS (Transport Layer Security), resulting in communication via the HTTPS protocol. Once the properties for secure communication are configured, TLS will automatically be switched on for the Execution Context Web Interface and the Platform Web Interface.
Crypto algorithms are in place in to ensure secure data communication. The default crypto algorithms used are AES. If you require to modify the default crypto algorithms, see 2.6.4 Platform Properties or 2.6.9 Desktop Properties.
