Title:
Chosen-ciphertext Secure Encryption from Hard Algebraic Set Systems
Authors: Ronald Cramer, Dennis Hofheinz, Eike Kiltz
Abstract:We put forward the new abstract framework of “hard algebraic set systems” that allows to construct efficient chosen-ciphertext secure encryption schemes under computational (rather than decisional) intractability assumptions. Our framework can be instantiated with both RSA and Diffie-Hellman type assumptions, but in itself is completely abstract.
