Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a radio base station device that controls terminal spoofing while suppressing an introduction cost.SOLUTION: A base station 10 comprises: a key management part 111 that holds first key information PMK; a key formation part 113 that forms second key information PMK1 by a first calculation using first identification information as specific identification information for a radio terminal, which is acquired from the radio terminal, and the first key information PMK; a key preventing part 114 that controls so tat the second key information PMK1 formed by the key formation part 113 is prevented to the radio terminal; a verification part 115 that acquires the identification information specified to the communication terminal which tries to perform radio data communication with the base station 10 as second identification information from a communication terminal, uses the first calculation using the second identification information and the first key information PMK, and verifies that the communication terminal holds the second key information PMK1; and a data communication part 116 that perform encrypted data communication with the communication terminal on the basis of the second key information PMK1 under one condition that success of the verification by the verification part 115 is determined.SELECTED DRAWING: Figure 6
【課題】導入コストを抑えながら端末のなりすましを抑制する無線基地局装置を提供する。【解決手段】基地局10は、第一鍵情報PMKを保有する鍵管理部111と、無線端末から取得した、無線端末に固有の識別情報である第一識別情報と、第一鍵情報PMKとを用いた第一演算により第二鍵情報PMK1を生成する鍵生成部113と、鍵生成部113が生成した第二鍵情報PMK1が無線端末に提供されるよう制御する鍵提供部114と、基地局10と無線データ通信しようとする通信端末に固有の識別情報を第二識別情報として通信端末から取得し、第二識別情報と第一鍵情報PMKとを用いた第一演算を利用して、通信端末が第二鍵情報PMK1を保有していることの検証を行う検証部115と、検証部115による検証が成功したと判定したことを条件の1つとして、第二鍵情報PMK1に基づいて暗号化されたデータ通信を通信端末と行うデータ通信部116とを備える。【選択図】図6 |
