- Java is a successful programming environment and its use has grown from little embedded applications until enterprise network servers based on J2EE. This intensive use of Java demands the validation of their fault tolerance mechanisms to avoid unexpected behavior of the applications at runtime. This paper describes the design and implementation of a fault injector for the "Exhaustif®" SWIFI tool. Aspecific fault model for java applications that include class corruption/substitution at loading time, method call interception and unexpected exception thrown is proposed. The injector uses the JVMTI (JavaVirtual Machine Tool Interface) to perform bytecode instrumentation at runtime to carry out the fault model previously defined. Finally a XML formalization of the specific Java fault model is proposed. This approach, JVMTI + XML fault model description, provides complete independency between the system under test and the fault injection tool, as well the interoperability with another SWIFI tools.

- This paper presents Exhaustif®, a SWIFI fault injection tool for fault tolerance verification and the validation of embedded software in distributedheterogeneous systems. Exhaustif® mainly consists of two parts: EEM and FIK. Exhaustif® Executive Manager (EEM) is a GUI Java application to define the fault injection campaign that uses a SQL database to save the test results obtained from the System under Test (SUT) in order to carry out a post injection data analysis. FIK is under the command of EEM to cary out fault injections in applications running under diverse operating systems using pure SWIFI techniques. Exhaustif® carries out floating point register and memory corruptions using temporary triggers and uses an optimized routine interception mechanism to cany out argument and return value corruption with a minimal time overhead. Two experimentalFault Injector Kernels (FIK) under the RTEMS operating system for an EADS-Astrium SPARC ERC32-based MCM processor board and i386 standard PC mainboard have been developed.

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

Konferensbidrag (refereegranskat)abstract
- 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.
