A security architecture for microprocessors
نویسنده
چکیده
The Security Architecture for Microprocessors (SAM ) is a lightweight and high-performance combined hardand software security extension for microprocessors. SAM has been designed to provide a secure remote code execution environment. It can be used to implement effective copy-protection schemes and provides mechanisms to prevent data and algorithm disclosure. SAM provides protection even if an attacker has full access to both the operating system and hardware. SAM uses an enhanced processor core which can be used as a drop in replacement for a standard processor to provide transparent encryption and hashing of memory contents to prevent external tampering and sniffing attacks. Further internal security-related extensions support a secure operating system implementation. Both the hardware and software design are presented in this thesis.

متن کاملA security framework for protecting traffic between collaborative domains
In this paper, we propose a novel Secure Name Service (SNS) framework for enhancing the service availability between collaborative domains (e.g., extranets). The key idea is to enforce packet authentication through resource virtualization and utilize dynamic name binding to protect servers from unauthorized accesses, denial of service (DOS) and other attacks. Different from traditional static n...
