Method and Apparatus for Securely Transmitting and Receiving Data in Peer-to-Peer Manner

摘要

A method and apparatus for securely transmitting data between embedded devices are provided. The method includes: issuing a request for a session key that is to be used in a session with the device; restoring the session key by deciphering a ciphered session key included in a response to the request; ciphering data using the restored session key; and transmitting the ciphered data. Accordingly, it is possible to enable embedded devices to securely communicate with one another in a peer-to-peer manner.
