Abstract
Ubiquitous computing has inherent features, e.g., a number of elements in the system with restricted communication and computation capabilities, which make harder to achieve dependability. In this work we explore this research line through the study of TrustedPals, a smartcard-based framework which allows implementing security policies in ubiquitous systems and applications in a decentralized way. The current architecture of TrustedPals uses a consensus algorithm adapted to the omission failure model. In this work, we propose to alternatively use the Paxos algorithm, in order to address more ubiquitous environments.
