Abstract. We present a non-interactive chosen ciphertext secure threshold encryption system. The proof of security is set in the standard model and does not use random oracles. Our...
Abstract. We present Minion, a new constraint solver. Empirical results on standard benchmarks show orders of magnitude performance gains over state-of-the-art constraint toolkits....
Knowing tourists' individual preferences provides the possibility to offer personalised tours. The challenge is to capture these preferences using a mobile device. During a f...
