Abstract
Security is a crucial element of information systems. Extensive research for cryptographic algorithms that provide the sound theoretical basis of security. Among them security and integrity of memory has been a longstanding issue in trusted system design. Main memory is a critical component of all computing systems. Most of those systems are vulnerable to memory attacks, in which an attacker gains physical accesses to the unattended hardware, obtains the decryption keys from memory. We propose a method for protecting memory systems against attacks with hardware authentication and full memory encryption. The method is secure against all known type of memory attack. We have tested the method with software simulator and Field Programmable Gate Array (FPGA) platform. The results show that the method can authenticate and encrypt the contents of DRAM with 2.5 % performance penalties.
