Abstract
A communication security method and apparatus of a first node and a second node are provided. The first node and the second node communicate with each other based on a full duplex communication scheme using a near field. In the communication security method and apparatus, information to be transmitted may be encrypted based on received information and the encrypted information may be transmitted, in a TX node and an RX node. The communication security method and apparatus prevent an additional node from decrypting the information, and ensure transmission and reception of reliable data. In addition, the communication security method and apparatus prevent information from being decrypted in a physical layer, by periodically or aperiodically exchanging a new encryption key.
