Impossibility on Tamper-Resilient Cryptography with Uniqueness Properties
black-box separation simulatable attack tamper-resilience
2018/6/5
In this work, we show negative results on the tamper-resilience of a wide class of cryptographic primitives with uniqueness properties, such as unique signatures, verifiable random functions, signatur...
On Metrics to Quantify the Inter-Device Uniqueness of PUFs
PUF Physically Unclonable Function Uniqueness
2016/3/23
Physically Unclonable Functions (PUFs) have been an emerging topic in hardware security and trust in recent years, and many different kinds of PUFs have been presented in the literature. An important ...
On the Resilience and Uniqueness of CPA for Secure Broadcast
ad hoc networks secure broadcast
2014/3/6
We consider the Secure Broadcast problem in incomplete networks. We study the resilience of the Certified Propagation Algorithm (CPA), which is particularly suitable for ad hoc networks. We address th...
Uniqueness is a Different Story: Impossibility of Verifiable Random Functions from Trapdoor Permutations

2010/12/22
Verifiable random functions (VRFs), firstly proposed by Micali, Rabin, and Vadhan (FOCS 99), are pseudorandom functions with the additional property that the owner of the seed $\vsk$ can issue publicl...
