We design a new (n, 1)-CPIR protocol BddCpir for -bit strings as a combination of a noncryptographic (BDD-based) data structure and a more basic cryptographic primitive (communicat...
Abstract. The term indistinguishability amplification refers to a setting where a certain construction combines two (or more) cryptographic primitives of the same type to improve t...
We consider the round complexity of a basic cryptographic task: verifiable secret sharing (VSS). This well-studied primitive provides a good "test case" for our understan...
Aggregation schemes allow to combine several cryptographic values like message authentication codes or signatures into a shorter value such that, despite compression, some notion o...
Data access in HPC infrastructures is realized via user-level networking and OS-bypass techniques through which nodes can communicate with high bandwidth and low-latency. Virtualiz...
