Blind Schnorr Signatures in the Algebraic Group Model
Schnorr signatures blind signatures algebraic group model
2019/8/2
We study the security of schemes related to Schnorr signatures in the algebraic group model (AGM) proposed by Fuchsbauer, Kiltz, and Loss (CRYPTO 2018), where the adversary can only compute new group ...
A publicly verifiable quantum blind signature scheme without entanglement based on asymmetric cryptography
Undeniable quantum signature scheme Impersonation attack Quantum asymmetric cryptography
2019/7/15
In recent years, several cryptographic scholars have proposed quantum blind signature schemes. However, their methods require the signatories and the inspectors to share common keys in advance, which ...
Proxy-Mediated Searchable Encryption in SQL Databases Using Blind Indexes
searchable encryption blind indexing SQL database security
2019/7/15
Rapid advances in Internet technologies have fostered the emergence of the “software as a service” model for enterprise computing. The “Database as a Service” model provides users with the power to cr...
A Modular Treatment of Blind Signatures from Identification Schemes
Blind signature identification schemes Forking Lemma
2019/3/6
We propose a modular security treatment of blind signatures derived from linear identification schemes in the random oracle model. To this end, we present a general framework that captures several wel...
Quantum-secure message authentication via blind-unforgeability
quantum quantum access model unforgeability
2018/12/3
Formulating and designing unforgeable authentication of classical messages in the presence of quantum adversaries has been a challenge, as the familiar classical notions of unforgeability do not direc...
Blind Certificate Authorities
anonymity MPC TLS
2018/11/2
We explore how to build a blind certificate authority (CA). Unlike conventional CAs, which learn the exact identity of those registering a public key, a blind CA can simultaneously validate an identit...
Complementary feeding with cowpea reduces growth faltering in rural Malawian infants: a blind, randomized controlled clinical trial
complementary feeding common bean cowpea legumes Malawi stunting environmental enteric dysfunction
2018/11/21
Background: Growth faltering is common in rural African children and is attributed to inadequate dietary intake and environmental enteric dysfunction (EED).
Quantity and source of dietary protein influence metabolite production by gut microbiota and rectal mucosa gene expression: a randomized, parallel, double-blind trial in overweight humans
dietary protein protein source high-protein diet gut microbiota
2018/11/19
Background: Although high-protein diets (HPDs) are frequently consumed for body-weight control, little is known about the consequences for gut microbiota composition and metabolic activity and for lar...

2018/11/16
Background: Although high-protein diets (HPDs) are frequently consumed for body-weight control, little is known about the consequences for gut microbiota composition and metabolic activity and for lar...
Intake of potassium- and magnesium-enriched salt improves functional outcome after stroke: a randomized, multicenter, double-blind controlled trial
stroke potassium magnesium enriched salt neurologic performance
2018/11/20
Background: Stroke is one of the leading causes of mortality and neurologic deficits. Management measures to improve neurologic outcomes are in great need. Our previous intervention trial in elderly s...
Conditional Blind Signatures
digital signatures blind signatures designated verifier signatures
2017/7/19
We propose a novel cryptographic primitive that we call conditional blind signatures. Our primitive allows a user to request blind signatures on messages of her choice. The signer has a secret Boolean...
Hacking in the Blind: (Almost) Invisible Runtime User Interface Attacks
serious violations input integrity
2017/6/22
We describe novel, adaptive user interface attacks, where the adversary attaches a small device to the interface that connects user input peripherals to the target system. The device executes the atta...
Probiotics (Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and Bifidobacterium longum MM-2) improve rhinoconjunctivitis-specific quality of life in individuals with seasonal allergies: a double-blind, placebo-controlled, randomized trial
healthy adults probiotics seasonal allergies allergic rhinitis quality of life Lactobacillus gasseri Bifidobacterium bifidum Bifidobacterium longum
2018/11/13
Background: Rhinoconjunctivitis-specific quality of life is often reduced during seasonal allergies. The Mini Rhinoconjunctivitis Quality of Life Questionnaire (MRQLQ) is a validated tool used to meas...
Efficient Round-Optimal Blind Signatures in the Standard Model
Blind Signatures Round-Optimal Partial Blindness
2017/2/20
Blind signatures are at the core of e-cash systems and has numerous other applications. In this work we construct efficient blind and partially blind signature schemes over bilinear groups in the stan...
