The future of Cybersecurity in Italy: Strategic focus area

This volume has been created as a continuation of the previous one, with the aim of outlining a set of focus areas and actions that the Italian Nation research community considers essential. The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

DATA SECURITY IN THE CLOUD USING SERPENT ENCRYPTION AND DISTRIBUTED STEGANOGRAPHY

Despite the enormous benefits derived from the adoption of cloud computing concept, its widespread acceptance has been considerably encumbered by security concerns. The enlarged attack surface in a cloud environment makes it more vulnerable to existing and emerging security threats. Conventional data security approaches have been found incapable in curtailing these threats and this unpleasant trend has necessitated the need for a futuristic approach to data security. Serpent encryption algorithm and distributed steganography are already proven techniques for securing data. This paper proposes an enhanced mechanism to ensuring data security by strategically combining serpent cryptographic algorithm and distributed steganography. The unified approach is aimed at leveraging the strength of these two proven techniques to achieve a robust mechanism for ensuring confidentiality and integrity of data in the cloud

Proxy Re-Encryption for Accelerator Confidentiality in FPGA-Accelerated Cloud

FPGAs offer many-fold acceleration to various application domains, and have become a part of cloud-based computation. However, their cloud-use introduce Cloud Service Provider (CSP) as trusted parties, who can access the hardware designs in plaintext. Therefore, the intellectual property of hardware designers is not protected against a dishonest cloud. In this paper, we propose a scheme for the confidentiality of accelerators on cloud, without limiting CSP to maintain their resources freely. Our proposed scheme is based on Proxy Re-Encryption which allows the developers to upload their accelerators to the CSPs under encryption. The CSPs cannot decrypt them; however, alter the encryption that allows the target FPGAs they pick to decrypt. In addition, our scheme allows metering the use of accelerators
