中文摘要 | 電子資訊產品大多數都有單晶片MPU 或專屬的CPU 嵌入於系統中,而 CPU 執行的程式通常放在程式記憶體(ROM)中,其扮演著系統運作之中樞,然而現今複製工具的進步與方便,使得花費數月的程式或版權資料,還來不及申請專利,可能就在瞬間被複製而受到相當大之損失。本研究乃針對如何延緩研發資料洩漏的時間,研製了一套低成本、使用方便以及抗複製的程式記憶體保護器模組。本研究運用Simplified DES 加解密演算法原理,並以CPLD 元件合成電路,與ROM 組成一整合的保護模組。其功能提供了預防複製以及非正常讀取資料程序的保護機制,模組內部運用快速比對察覺電路、虛擬私密金鑰技術,會及時監控讀取資料之程序,經實際驗證結果,擁有不錯的資料保護效能,因此可達到研發資料保護之目的。 |
英文摘要 | Most electronic information products have a single-chip MPU or a proprietary CPU embedded in the system. The execution program of the CPU is usually stored in the ROM, playing a pivotal role in the system operation. As a consequence of advanced duplication technology, the programs or copyrighted documents which take a lot of time to complete can be duplicated in just a few minutes. This often causes loss of big money. The present research attempts to find a low-cost, convenient method (anti-duplication program-protection module) of copyright protection. Based on the Simplified DES encryption principle, we combine a CPLD component integrated circuit with ROM into an integrated protection module. This module serves as a protection mechanism that prevents duplication and abnormal retrieval of information. It uses rapid detection of circuit duplication and virtual secret-key techniques to monitor retrieval procedures in real-time. The experimental results demonstrate that this module is able to prevent illegal duplication effectively. |
