Zero-Knowledge and Code Obfuscation
In this paper, we investigate the gap between auxiliary-input zero-knowledge (AIZK) and blackbox-simulation zero-knowledge (BSZK). It is an interesting open problem whether or not ...

Group Key Exchange Enabling On-Demand Derivation of Peer-to-Peer Keys
We enrich the classical notion of group key exchange (GKE) protocols by a new property that allows each pair of users to derive an independent peer-to-peer (p2p) key on-demand and ...

POSH: Proactive co-Operative Self-Healing in Unattended Wireless Sensor Networks
Unattended Wireless Sensor Networks (UWSNs) are composed of many small resource-constrained devices and operate autonomously, gathering data which is periodically collected by a v...

Non-malleable extractors and symmetric key cryptography from weak secrets
We study the question of basing symmetric key cryptography on weak secrets. In this setting, Alice and Bob share an n-bit secret W, which might not be uniformly random, but the ad...

Strongly Multiplicative and 3-Multiplicative Linear Secret Sharing Schemes
Strongly multiplicative linear secret sharing schemes (LSSS) have been a powerful tool for constructing secure multi-party computation protocols. However, it remains open whether o...
