Modelling and simulation of a biometric identity-based cryptography
Government information is a vital asset that must be kept in a trusted environment and efficiently managed by authorised parties. Even though e-Government provides a number of advantages, it also introduces a range of new security risks. Sharing confidential and top-secret information in a secure manner among government sectors tend to be the main element that government agencies look for. Thus, developing an effective methodology is essential and it is a key factor for e-Government success. The proposed e-Government scheme in this paper is a combination of identity-based encryption and biometric technology. This new scheme can effectively improve the security in authentication systems, which provides a reliable identity with a high degree of assurance. In addition, this paper demonstrates the feasibility of using Finite-state machines as a formal method to analyse the proposed protocols

Trusted Launch of Virtual Machine Instances in Public IaaS Environments
Cloud computing and Infrastructure-as-a-Service (IaaS) are emerging
and promising technologies, however their adoption is hampered by data security
concerns. At the same time, Trusted Computing (TC) is experiencing an increasing
interest as a security mechanism for IaaS. In this paper we present a protocol
to ensure the launch of a virtual machine (VM) instance on a trusted remote
compute host. Relying on Trusted Platform Module operations such as binding
and sealing to provide integrity guarantees for clients that require a trusted VM
launch, we have designed a trusted launch protocol for VM instances in public IaaS
environments. We also present a proof-of-concept implementation of the protocol
based on OpenStack, an open-source IaaS platform. The results provide a basis
for the use of TC mechanisms within IaaS platforms and pave the way for a wider
applicability of TC to IaaS security
