A major Atlantic ocean current -- the Atlantic Meridional Overturning Circulation, or AMOC -- may have been losing stability in the course of the last century, according to new research. A potential c...
We examine all of the signature submissions to Round-2 of the NIST PQC ``competition'' in the context of whether one can transform them into threshold signature schemes in a relatively straight forwar...
Threshold Implementations (TI) are secure algorithmic countermeasures against side-channel attacks in the form of differential power analysis. The strength of TI lies in its minimal algorithmic requir...
A surge in DNS cache poisoning attacks in the recent years generated an incentive to push the deployment of DNSSEC forward. ICANN accredited registrars are required to support DNSSEC signing for their...
In a secret sharing scheme, a secret value is encrypted into several shares, which are distributed among corresponding participants. It requires that only predefined subsets of participants can recons...
Cryptocurrency applications have spurred a resurgence of interest in the computation of ECDSA signatures using threshold protocols---that is, protocols in which the signing key is secret-shared among ...
Threshold private set intersection enables Alice and Bob who hold sets AA and BB of size nn to compute the intersection A∩BA∩B if the sets do not differ by more than some threshold parameter tt. In th...
In this work, we revisit multi-authority attribute based signatures (MA-ABS), and elaborate on the limitations of the current MA-ABS schemes to provide a hard to achieve (yet very useful) combination ...
A threshold signature scheme enables distributed signing among nn players such that any subgroup of size t+1t+1 can sign, whereas any group with tt or fewer players cannot. While there exist previous ...
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...
Threshold Implementations are well-known as a provably firstorder secure Boolean masking scheme even in the presence of glitches. A precondition for their security proof is a uniform input distributio...
Token-based authentication is commonly used to enable a single-sign-on experience on the web, in mobile applications and on enterprise networks using a wide range of open standards and network authent...
Threshold implementations have emerged as one of the most popular masking countermeasures for hardware implementations of cryptographic primitives. In the original version of TI, the number of input s...
We explore large-scale fault-tolerant multiparty computation on a minimal communication graph. Our goal is to be able to privately aggregate data from thousands of users - for example, in order to obt...
An Oblivious PRF (OPRF) is a protocol between a server holding a key to a PRF and a user holding an input. At the end of the interaction, the user learns the output of the OPRF on its input and nothin...
