Code-based protection method for satellite-borne computer information security storage process

The invention discloses a coding-based protection method for an information security storage process of a spaceborne computer, which comprises the following steps of: firstly, finding a physical address of information needing to be protected in an ROM (Read Only Memory) of the spaceborne computer, and respectively extracting a data segment and a code segment of binary information from the physical address; and the information of the code segments is coded by using a coding algorithm and then is rewritten into the corresponding segments. When the information is loaded into the memory, the information can be decoded firstly, and then the decoded information is loaded into the memory. According to the method, the information is protected in a coding mode, the bit inversion problem caused by space radiation in the information storage process can be reduced, and a reliable protection result is given. 本发明公开了一种针对星载计算机信息安全存储过程中基于编码的防护方法，首先在星载计算机的ROM中找到需要防护的信息的物理地址，从物理地址中分别提取出二进制信息的数据段和代码段，使用编码算法对代码段的信息进行编码后再重新写入到相应的段
