Secure integration of asymmetric and symmetric encryption schemes. (English) Zbl 0942.94019
Wiener, Michael (ed.), Advances in cryptology - CRYPTO ’99. 19th annual international cryptology conference Santa Barbara, CA, USA, August 15-19, 1999. Proceedings. Berlin: Springer. Lect. Notes Comput. Sci. 1666, 537-554 (1999).
Summary: This paper shows a generic and simple conversion from weak asymmetric and symmetric encryption schemes into an asymmetric encryption scheme which is secure in a very strong sense – indistinguishability against adaptive chosen-ciphertext attacks in the random oracle model. In particular, this conversion can be applied efficiently to an asymmetric encryption scheme that provides a large enough coin space and, for every message, many enough variants of the encryption, like the ElGamal encryption scheme.
