Device and method in wireless communication system and wireless communication system

A device, comprising:

• processing circuitry configured to
• establish, in response to a connection request from a first apparatus, a secure communication channel between the first apparatus and a second apparatus;
• protect service data using a data security key;
• generate cipher text data from the protected service data using a channel key;
• and
• transmit the generated cipher text data on the secure communication channel, wherein
• the channel key is extracted by the first apparatus from the secure communication channel,
• the data security key is generated by the first apparatus based on at least the channel key extracted from the secure communication channel.

A communication system, comprising:

• a first apparatus including first processing circuitry configured to:
• establish a secure communication channel with a second apparatus,
• extract a channel key from the secure communication channel,
• generate a data security key for protecting service data based on at least the extracted channel key,
• protect the service data using the generated data security key,
• generate cipher text data from the protected service data using the extracted channel key, and
• transmit the generated cipher text data to the second apparatus on the secure communication channel;
• and
• the second apparatus including second processing circuitry configured to:
• establish, in response to a connection request from the first apparatus, the secure communication channel with the first apparatus, and
• receive the generated cipher text data from the first apparatus.

A method, comprising:

• establishing, using processing circuitry, a secure communication channel between a first apparatus and a second apparatus;
• extracting a channel key from the secure communication channel;
• generating a data security key for protecting service data based on at least the extracted channel key;
• protecting the service data using the generated data security key;
• generating cipher text data from the protected service data using the extracted channel key;
• and
• transmitting the generated cipher text data on the secure communication channel.

A non-transitory computer readable medium including executable instructions, which when executed by a computer cause the computer to:

• establish a secure communication channel between a first apparatus and a second apparatus;
• extract a channel key from the secure communication channel;
• generate a data security key for protecting service data based on at least the extracted channel key;
• protect the service data using the generated data security key;
• generate cipher text data from the protected service data using the extracted channel key;
• and
• transmit the generated cipher text data on the secure communication channel.
