On insecurity of Naor-Pinkas' distributed oblivious transfer
This paper analyses the security of Naor-Pinkas' distributed oblivious transfer [M. Naor, B. Pinkas, Distributed oblivious transfer, in: Advances in Cryptology-Proceedings of ASIACRYPT'00, Lecture Notes in Computer Science, vol. 1976, Springer-Verlag, 2000]. It is shown that the schemes presented in the paper do not protect the chooser/sender in the information theoretic sense. (C) 2007 Elsevier B.V. All rights reserved.
