Electronic device for transmitting and receiving end-to-end encrypted data based on attestation of electronic device and thereof operation method in wireless communication system

A method of a second electronic device which is connected to a fabric network supporting end-to-end encryption (E2EE) in a wireless communication system, the method comprising:

• generating a second member key based on a pre-stored second device key;
• transmitting the second member key to a first electronic device through a fabric server, which manages the fabric network, and a service server, which manages service data;
• receiving a fabric key generated based on the second member key and a first member key of the first electronic device from the first electronic device through the fabric server and the service server;
• receiving service data encrypted based on the fabric key from the first electronic device through the service server;
• and
• decrypting the encrypted service data based on the fabric key.

One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by one or more processors of a first electronic device, cause the first electronic device to perform operations, the operations comprising:

• generating a fabric key based on a pre-stored first device key and a second member key received from a second electronic device;
• transmitting the fabric key to the second electronic device through a fabric server, which manages the fabric network, and a service server, which manages service data;
• encrypting service data based on the fabric key;
• and
• transmitting the encrypted data to the second electronic device through the service server,
• wherein the fabric key is shared with the fabric server, which is a member entity of the fabric network, and the second electronic device, and
• wherein the encrypted data is decryptable at a member entity of the fabric network that shares the fabric key.
