7 Security Aspects
Authentication and Transport Layer Security can be established when the oneM2M entity which hosts the WebSocket Server can be addressed with the wss URI scheme. When using the wss URI scheme, one of the Security Association Establishment Frameworks (SAEF) as defined in ETSI TS 118 103 [4] shall be applied to provide mu...
