A Memory Integrity Protection Method Based on Bloom Filter

Today, attackers are capable of using software or hardware 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 caused tremendous losses. Focus on this question, this paper proposed new architectural mechanisms to ensure data integrity which improved previous work in this area without compromising security. The new integrity mechanism offers significant higher performance, space advantages and adjustable level of security over existing ones. This paper evaluated the overhead of the scheme and compared it with the conventional integrity checking scheme CHTree. For most benchmarks, the overhead of the new method is much better.
