Linearly-Homomorphic Signatures and Scalable Mix-Nets
Anonymity random shuffling linearly-homomorphic signatures
2019/5/23
Anonymity is a primary ingredient for our digital life. Several tools have been designed to address it such as, for authentication, blind signatures, group signatures or anonymous credentials and, for...
Shuffle and Mix: On the Diffusion of Randomness in Threshold Implementations of Keccak
side-channel analysis threshold implementation uniformity
2018/11/13
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...
Securing Abe's Mix-net Against Malicious Verifiers via Witness Indistinguishability
mix-nets witness indistinguishability Benes network
2017/6/9
We show that the simple and appealing unconditionally sound mix-net due to Abe (Asiacrypt'99) can be augmented to further guarantee anonymity against malicious verifiers. This additional guarantee imp...
Formal Analysis of Chaumian Mix Nets with Randomized Partial Checking
Chaumian Mix Nets Privacy Verifiability
2016/1/9
Mix nets with randomized partial checking (RPC mix nets) have been introduced by
Jakobsson, Juels, and Rivest as particularly simple and efficient verifiable mix nets. These
mix nets have been used ...
Re-Encryption randomized partial checking (RPC) mix nets were introduced
by Jakobsson, Juels, and Rivest in 2002 and since then have been employed
in prominent modern e-voting systems and in politic...

Network Topology and Time Criticality Effects in the Modularised Fleet Mix Problem
Network Topology Time Criticality Effects Modularised Fleet Mix Problem
2015/7/29
In this paper, we explore the interplay between network topology and time criticality in a military logistics system. A general goal of this work (and previous work) is to evaluate land transportation...

In this paper, we explore the interplay between network topology and time criticality in a military logistics system. A general goal of this work (and previous work) is to evaluate land transportation...
To efficiently store, retrieve and update the globalspatial data, a hierarchical and dynamic data model on a globalscale is urgently needed.
The QTM (Quaternary Triangular Mesh) as a hierarchical qua...
Mix it Up, Mix it Down: Intriguing Implications of Ocean Layering
Ocean Layering Intriguing
2015/7/3
Using a physical simulation, we explore the vertical density structure within the ocean and how layering (density stratification) controls water motion, impedes nutrient transport, and regulates biolo...
The influence of industry mix on regional new firm entry
Area Entrepreneurial environment Metal oxide semiconductor
2014/11/28
Per capita rates of entry are commonly used to measure regional entrepreneurial climate. Yet entry rates vary widely by industry and tend to mirror existing regional specializations. Without controlli...
Impact of different bioenergy crops on area allocation and cellulosic ethanol feedstock mix
perennial grasses land use
2014/11/27
Although a cellulosic ethanol mandate for 2022 is in place, significant political, economic, and agronomic uncertainty exists surrounding the attainability of the mandate. This paper evaluates the eff...
选择密文安全的可验证Mix-Net协议
混合网络 秘密混洗证明 选择密文安全 电子选举
2015/12/21
提出了一种在选择密文攻击下可证明安全的可验证Mix-Net协议。在Wikstr?m Mix-Net方案基础上,引入了新的密钥生成算法和秘密混洗零知识证明构造方法,提高了安全性。在不暴露输入密文与输出明文匹配关系的条件下,任何人都可以根据Mix服务器公布的证据验证输出结果的正确性,即满足可公开验证性;任意发送者还可以追踪和检验自己输入的密文的处理过程,即满足发送者可验证性。基于随机预言机假设证明了该...
