摘　　要：针对安卓手机的安全保护机制,提出了一种基于单分组散列函数的数字签名机制和关键资源保护机制相结合的保护方案.首先该方案通过安全文件生成器将关键资源文件的哈希值保存到安全文件中,然后使用数字签名机制保证安全文件不被篡改,最后由关键资源保护机制确保关键资源文件的完整性,其中包括对被篡改的关键资源进行纠错.实验结果表明,本方案不仅能够有效地防止安卓应用程序被篡改,而且增加了逆向攻击的难度.According to the security protection mechanism of Android mobile phone, a protection scheme based on single block hash function and digital signature mechanism is proposed. The first hash file generator will be the key security resource files saved to the file security value through the program, to ensure the safety of the file has not been tampered and then use the digital signature mechanism, and finally by the key resource protection mechanism to ensure the integrity of key resource files, including error correction of key resources has been tampered with. The experimental results show that the proposed scheme can not only prevent the Android application from being tampered with, but also increase the difficulty of reverse attack.
