PURPOSE: A method and an apparatus for ciphering/decoding end-to-end data in a wireless data communication are provided to shorten a ciphering/decoding time and embody a ciphering/decoding algorithm in a wireless terminal. CONSTITUTION: A wireless terminal(100) requests connection to a server(200)(S11). The server(200) permits the connection request to the wireless terminal(100) and sets the connection(S12). The wireless terminal(100) transmits a base value necessary for generating a key used in a wireless data cipher/decoding to the server(200)(S13). The server(200) receives the base value and transmits an offset value necessary for generating the key to the wireless terminal(100)(S14). All wireless data transmitted and received between the wireless terminal(100) and the server(200) are ciphered by the key to be transmitted(S15,S16), and an object decodes the received cipher sentence by the key and sees the data. |
