ASA : advanced secure architecture for preventing unauthorized access in personal computer platforms and BIOS

This paper proposes an architecture for Personal Computers (PC) to avoid BIOS alteration and unauthorized access to resources. This proposal is based on results obtained from study of most popular PC platforms security mechanisms. Authentication controls which are established in PC platform in order to grant operating system booting or BIOS integrity of code mechanism incorporated to secureand avoid executing disallowed code are quite easy to break. The architecture described in the present work (Advanced Secure Architecture - ASA) increase the overall information and system security since prevents an unauthorized platform booting and it provides procedures for BIOS code authentication. On the other hand, ASA overcomes the users' authentication challenge in a corporative environment as well as it offers a very flexible way to specify the Personal Computers Corporation set that a user is allowed to access.
