Evaluating 2-DNF Formulas on Ciphertexts
Let ψ be a 2-DNF formula on boolean variables x1, . . . , xn ∈ {0, 1}. We present a homomorphic public key encryption scheme that allows the public evaluation of ψ given an en...

Forward-Secure and Searchable Broadcast Encryption with Short Ciphertexts and Private Keys
We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...

Between Hashed DH and Computational DH: Compact Encryption from Weaker Assumption
In this paper, we introduce the intermediate hashed Diffie-Hellman (IHDH) assumption which is weaker than the hashed DH (HDH) assumption (and thus the decisional DH assumption), a...

New Techniques for Anonymous HIBE with Short Ciphertexts in Prime Order Groups
Anonymous hierarchical identity based encryption (HIBE) is an extension of identity based encryption (IBE) that can use an arbitrary string like an e-mail address for a public key...

On the security of a class of image encryption schemes
— Recently four chaos-based image encryption schemes were proposed. Essentially, the four schemes can be classified into one class, which is composed of two basic parts: permuta...
