Probabilistic and nondeterministic aspects of Anonymity 1
نویسنده
چکیده
Anonymity means that the identity of the user performing a certain action is maintained secret. The protocols for ensuring anonymity often use random mechanisms which can be described probabilistically. The user, on the other hand, may be selected either nondeterministically or probabilistically. We investigate various notions of anonymity, at different levels of strength, for both the cases of probabilistic and nondeterministic users.

Probabilistic and nondeterministic aspects of anonymity
The concept of anonymity comes into play in a wide range of situations, varying from voting and anonymous donations to postings on bulletin boards and sending emails. The protocols for ensuring anonymity often use random mechanisms which can be described probabilistically, while the agents’ behavior may be totally unpredictable, irregular, and hence expressible only nondeterministically. Formal...

متن کاملWeak Probabilistic Anonymity 1 Yuxin Deng
Anonymity means that the identity of the user performing a certain action is maintained secret. The protocols for ensuring anonymity often use random mechanisms which can be described probabilistically. In this paper we propose a notion of weak probabilistic anonymity, where weak refers to the fact that some amount of probabilistic information may be revealed by the protocol. This information c...
