Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for establishing a secure destination address range responsive to initiation of direct memory access (DMA) operation.SOLUTION: A method allows decrypted content obtained as encrypted content from a source memory to be placed at a destination memory on the basis of whether destination memory addresses of the destination memory fall within a secure destination address range.SELECTED DRAWING: Figure 1 【課題】ダイレクトメモリアクセス（ＤＭＡ）動作の開始に応答して安全な宛先アドレス範囲を確立する方法を提供する。【解決手段】ソースメモリから暗号化されたコンテンツとして取得される復号化されたコンテンツが、宛先メモリの宛先メモリアドレスが安全な宛先アドレス範囲内であるかどうかに基づいて、宛先メモリに置かれることを許可する。【選択図】図１
