Kamara Lectures 2 + 3 : Provable Security
The design of cryptographic algorithms presents certain unique challenges. Over time, we have learned that our intuition about what is secure and what is not is very poor. The history of cryptography is filled with examples of cryptosystems that were thought to be highly-secure but turned out to be completely broken. In addition, unlike other areas of computer science, we have no way of testing...

متن کاملLogarithmic operators in SL ( 2 , IR ) WZNW model , Singletons and
We discuss the role of singletons and logarithmic operators in AdS 3 string theory in the context of AdS 3 /CF T 2 correspondence.
متن کاملEverything Provable is Provable in Zero-Knowledge
Assuming the existence of a secure probabilistic encryption scheme, we show that every language that admits an interactive proof admits a (computational) zero-knowledge interactive proof. This result extends the result of Goldreich, MiCali and Wigderson, that, under the same assumption, all of NP admits zero-knowledge interactive proofs. Assuming envelopes for bit commitment, we show t h t ever...
متن کاملSingletons and Neutrinos
The first half is a rapid review of 30 years of work on physics in antiDe Sitter space, with heavy emphasis on singletons. Principal topics are the kinematical basis for regarding singletons as the constituents of massless particles, and the effect of (negative) curvature in the infrared domain. Ideas that lead to an alternative to Big Bang cosmology are merely sketched. The second half present...
