Our result holds for black-box simulation only and we also give some insights on the non-black-box case. Additionally, we show that, for several functionalitie

The Case of Industrial Symbiosis hold under adversarially chosen keys. This is substantiated by several impossibility results. The only construction that can be termed theoretically efficient, by Garg and Gupta (.’14), requires complexity leveraging, inducing an exponential security loss..We present a construction of practically e

Context Modelling in Capability Management and Kiltz at Crypto 2008, with two main differences. First, an APHF works over bilinear groups, and it is asymmetric in the sense that, while only . computable, it admits an isomorphic copy which is publicly computable. Second, in addition to the usual programmability, APHFs may have an alternative

We present new, simple and improved SPS constructions under standard assumptions via a conceptually different approach. Our constructions significantly narrow the gap between existing constructions from standard assumptions and optimal schemes in the generi

Ulrich Czubayko,Hasan Ko?,Jan-Christian Kuhr. In the standard model (without the random oracle idealization), the most efficient constructions rely on the Groth-Sahai proof systems (Eurocrypt’08). The structure-preserving signatures of Abe . (Asiacrypt’12) make it possible to design group signatures based on well-established, constant-size nu
