On Randomness Leakage in Public-Key Encryption

Abstract (in Japanese) (See Japanese page) 
(in English) We consider the problem of constructing public-key encryption schemes that are resilient to leaking the randomness used in the encryption algorithm. Recently, Naor and Segev (CRYPTO2009) showed that public-key encryption schemes which are resilient to key leakage are generally constructed from hash proof systems. However the situation of randomness leakage in the encryption algorithm has never been considered. In this paper, we formalize the attacks on randomness leakage, and propose new security notions of public-key encryption. We give a general construction of public-key encryption schemes which are resilient to the randomness-leakage attacks. Furthermore, we extend our general construction in order to prevent both the key-leakage and the randomness-leakage attacks.
This article is a technical report without peer review, and its polished version wil l be published elsewhere.
