Abstract
Disclosed is a method of performing, by a first device, short-range wireless communication with a second device, the method including receiving, from the second device, second authentication information encrypted using first authentication information of the first device, decrypting the encrypted second authentication information by using the first authentication information, determining a secret key based on the decrypted second authentication information, and performing communication between the first device and the second device by using the determined secret key.
Claims11
A method comprising:
- transmitting, by a first electronic device to a second electronic device, a first public key;
- encrypting, by the second electronic device, a second public key based on the first public key;
- obtaining, by the first electronic device from the second electronic device, the encrypted second public key that was encrypted using the transmitted first public key;
- decrypting, by the first electronic device, the encrypted second public key by using the first public key;
- generating, by the first electronic device, a secret key based on a first private key and the second public key;
- obtaining, by the first electronic device from the second electronic device, an encrypted network key, wherein a network key is encrypted based on a secret key generated, at the second electronic device based on the first public key and a second private key;
- decrypting, by the first electronic device, the encrypted network key by using the secret key;
- establishing an encrypted communication channel between the first electronic device and the second electronic device by using the network key;
- and
- performing communication, by the first electronic device, with the second electronic device by using the encrypted communication channel.
