This correspondence studies the distributed secret sharing problem which is a twist of the classical secret sharing problem. In this new problem, each user needs to encode his or her own unique secret message without collaboration with other users and without the use of any common secret materials or cryptographic keys. The goal is to ensure that an adversary without access to all of the encode...

Abstract According to Dreyfusian anti-intellectualism, know-how or expertise cannot be explained in terms of know-that and its cognates but only intuition. Hubert Dreyfus Stuart do not exclude explaining skilled action. However, they think that (such as calculative deliberation perspectival deliberation) operate either below above the level expertise. In agreement with some critics Dreyfus, thi...

In this paper we propose a general definition of secrecy for cryptographic protocols in the Dolev-Yao model. We give a sufficient condition ensuring secrecy for protocols where rules have encryption depth at most two, that is satisfied by almost all practical protocols. The only allowed primitives in the class of protocols we consider are pairing and encryption with atomic keys. Moreover, we de...
