<p>The invention relates to a communication device (1) comprising a processor configured to create a client handshake message in order to negotiate security settings for a network connection between the device and a network node (2) of the telecommunication network using a transport layer security protocol. The client handshake message comprises a first encryption algorithm indicator indicative of a first encryption algorithm proposed by the communication device for communication from the communication device (1) to the network node (2), and a second encryption algorithm indicator indicative of a second encryption algorithm proposed by the communication device for communication from the network node to the communication device (1). Only one of the first and second encryption algorithm indicator indicates that communication is non-encrypted while the other of the first and second encryption algorithm indicator is indicating that communication is encrypted. This enables e.g. a gateway to perform deep packet inspection in one direction while in the opposite direction the data is still safely encrypted.</p> |
