Ninja: non identity based, privacy preserving authentication for ubiquitous environments

摘要: Most of today's authentication schemes involve verifying the identity a principal in some way. This process is commonly known as entity authentication. In emerging ubiquitous computing paradigms which are highly dynamic and mobile nature, may not be sufficient or even appropriate, especially if principal's privacy to protected. order preserve privacy, other attributes (e.g. location trustworthiness) need authenticated verifier. this paper we propose Ninja: non-identity-based scheme for environment, trustworthiness user's device anonymously remote Service Provider (verifier), during service discovery process. We show how can achieved using Trusted Computing functionality.
