چکیده

The well known Decisional Diffie-Hellman assumption states that given g, g and g, for random a, b, the element g is pseudo-random. Canetti in [Can97] introduced a variant of this assumption in which b is still random but a is drawn according to some well-spread distribution. In this paper we prove that his assumption holds in the generic group model and demonstrate its broad applicability in the context of leakage resilient cryptography.

How powerful are the DDH hard groups?

The question whether Identity-Based Encryption (IBE) can be based on the Decisional DiffieHellman (DDH) assumption is one of the most prominent questions in Cryptography related to DDH. We study limitations on the use of the DDH assumption in cryptographic constructions, and show that it is impossible to construct a secure Identity-Based Encryption system using, in a black box way, only the DDH...

DDH-Like Assumptions Based on Extension Rings

We introduce and study a new type of DDH-like assumptions based on groups of prime order q. Whereas standard DDH is based on encoding elements of Fq “in the exponent” of elements in the group, we ask what happens if instead we put in the exponent elements of the extension ring Rf = Fq[X]/(f) where f is a degree-d polynomial. The decision problem that follows naturally reduces to the case where ...
