A Memory and Disk Integrity Protection Scheme

Recently, data integrity in computer major becomes concern. The attackers are capable of using various methods to intrude computer network system. The phenomena of confidential information being tampered with or disclosed are emerging everywhere. Hardware-based attacks have emerged and have caused tremendous losses even threaten national security. Existing most of integrity verification designs have the characters of high operation overhead and only protect main memory. This paper presented an integrity protection scheme which can protect main memory and hard disk simultaneously. The scheme maintains an array on trusted on-chip storage to verify the data integrity. It can implement verification through each memory operations. Evaluation results showed that our scheme can protect data integrity of single processor with low overhead and high performance.
