Architecture Support for Memory Confidentiality and Integrity in Embedded Systems

Architecture Support for High Speed Protection of Memory Integrity and Confidentiality in Symmetric Multiprocessor Systems

Recently there is a growing interest in both the architecture and the security community to create a hardware based solution for authenticating system memory. As shown in the previous work, such silicon based memory authentication could become a vital component for creating future trusted computing environments and digital rights protection. Almost all the published work have focused on authent...

Architectural Support for Protecting Memory Integrity and Confidentiality

Low latency Solution for Confidentiality and Integrity Checking in Embedded Systems with Off-Chip Memory

This paper proposes a complete hardware solution for embedded systems that fully protects off-chip memory. Our security core is based on one-time pad (OTP) encryption and a CRC integrity check module. These modules safeguard external memories for embedded processors against a series of well-known attacks, including replay attacks, spoofing attacks and relocation attacks. The implementation limi...

Security extensions for integrity and confidentiality in embedded processors

With current trends toward embedded computer systems’ ubiquitous accessibility, connectivity, diversification, and proliferation, security becomes a critical issue in embedded computer systems design and operation. Embedded computer systems are subjected to both software and physical attacks aimed at subverting system operation, extracting key secrets, or intellectual property theft. We propose...

Insider threat: memory confidentiality and integrity in the cloud

The advantages of always available services, such as remote device backup or data storage, have helped the widespread adoption of cloud computing. However, cloud computing services challenge the traditional boundary between trusted inside and untrusted outside. A consumer’s data and applications are no longer in premises, fundamentally changing the scope of an insider threat. This thesis looks ...
