A component-based framework for certification of components in a cloud of HPC services

HPC Shelfis a proposal of a cloud computing platform to provide component-oriented services for High Performance Computing (HPC) applications. This paper presents a Verification-as-a-Service (VaaS) framework for component certification onHPC Shelf. Certification is aimed at providing higher confidence that components of parallel computing systems ofHPC Shelfbehave as expected according to one or more requirements expressed in their contracts. To this end, new abstractions are introduced, starting with certifier components. They are designed to inspect other components and verify them for different types of functional, non-functional and behavioral requirements. The certification framework is naturally based on parallel computing techniques to speed up verification tasks.NORTE-01-0145- FEDER-000037

Cryptographic extensions for custom and GPU-like architectures

The PhD thesis work deals with the exploration of hardware architectures dedicated to cryptographic applications, in particular, solutions based on reconfigurable hardware, such as FPGA. The thesis presents the results achieved for the acceleration of operations essential to homomorphic cryptography, specifically, the integer multiplication of very long operands, based on the Schonhage-Strassen algorithm and implemented with an ad-hoc FPGA hardware. Then, the thesis reports the exploration of novelty approaches for cryptographic acceleration, based on vectorial dedicated architectures, software programmable, with the corresponding implementation of symmetric and public key operations (namely, AES encryption and Montgomery multiplication) with improved performances

Critical systems verification in MetaMORP(h)OSY

Multi Agent Systems (MAS) methodologies are emerging as a new approach for modeling and developing complex distributed sys- tems. When complex constraints have to be veried on critical systems Model Driven Engineering (MDE) methodologies allow for the design and implementation of systems correct by construction. Usually verication is enforced by formal analysis. This paper presents MetaMORP(h)OSY (Meta-modeling of Mas Object-based with Real-time specication in Project Of complex SYstems) methodology and framework. They pro- vide a mean for building MAS models used to verify properties (and requirements) of Critical Systems following a MDE approach. In partic- ular, this work describes model transformation algorithms used in Meta- MORP(h)OSY to verify real-time and timed reachability requirements
