用数字签名解决应用程序被篡改的问题

Discussion on Tampering Problem of Applied Program with Digital Signature

目前应用程序被病毒、黑客或载体损坏等因素蓄意破坏或无意更改的情况十分普遍,采用基于公钥密码算法的数字签名可以充当"身份证"的角色,能够很好地解决目前应用程序被篡改的问题。介绍了密码算法的基本原理,给出了数字签名的解决方案。

Currently the conditions of applied program being tampered by the virus, hacker and carrier's failure intentionally or accidentally is very popular. Based on public key cryptographic Algorithms is illustrated, which can be regarded as identification card and can properly solve the tampering problem of applied program. The principles of cryptographic algorithm are analysed , and the plan of solving tampering problem of applied program with digital signature is proposed in detail. 
