基于汇编指令译码映射关系的软件代码安全分析

代码安全是计算机安全很重要的一个方面,所有的计算机软件归根结底都是代码,所以计算机代码安全是整个计算机系统安全的基石。以XOR、MOV、ADD、ADC等指令译码为例,分别就指令系统、教材阐述、软件代码等方面来探讨软件代码安全的问题,进而得出"软件安全与否不一定取决于源程序代码的公开与否"的观点。

Software Code Security Analysis Based on Assembler Instruction Decoding Mappings

Code security is a very important aspect of computer security, and all computer software are ultimately composed by the codes. Therefore the computer code security is a cornerstone of the whole computer system security. This paper researches the information security issues in many aspects such as instruction system, textbooks elaboration, software security based on analysis of XOR, MOV, ADD, ADC instruction decoding and so on. The paper finally comes to a conclusion that software security does not necessarily depend on whether or not the source code is open.
