Multi-owner Secure Encrypted Search Using Searching Adversarial Networks
Searchable Symmetric Encryption Multi-owner Ranked Search
2019/8/14
Searchable symmetric encryption (SSE) for multi-owner model draws much attention as it enables data users to perform searches over encrypted cloud data outsourced by data owners. However, implementing...
Multi-client Secure Encrypted Search Using Searching Adversarial Networks
Searchable Encryption Multi-keyword Ranked Search Multi-owner Model
2019/8/8
With the rapid development of cloud computing, searchable encryption for multiple data owners model (multi-owner model) draws much attention as it enables data users to perform searches on encrypted c...
ABFKS: Attribute-Based Encryption with Functional Keyword Search in Fog Computing
Attribute-based encryption Keyword search Fog computing
2019/8/2
We provide a new frame in this paper, the ciphertext-policy attribute-based encryption with functional keyword search (ABFKS) in fog computing. The ABFKS achieves functional keyword search and peer-pe...

Decentralized search forest?firefighting formation control multi-unmanned aerial vehicle (UAV) system Oxyrrhis Marina-inspired search (OMS)
2024/2/27
This paper presents an Oxyrrhis Marina-inspired search and dynamic formation control (OMS-DFC) framework for multi-unmanned aerial vehicle (UAV) systems to efficiently search and neutralize a dynamic ...
Related-Key Boomerang Attacks on GIFT with Automated Trail Search Including BCT Effect
Boomerang connectivity table GIFT Automatic search
2019/6/10
In Eurocrypt 2018, Cid et al. proposed a novel notion called the boomerang connectivity table, which formalised the switch property in the middle round of boomerang distinguishers in a unified approac...
Efficient Search for Optimal Diffusion Layers of Generalized Feistel Networks
Diffusion Round Feistel Permutations
2019/5/23
The Feistel construction is one of the most studied ways of building block ciphers. Several generalizations were then proposed in the literature, leading to the Generalized Feistel Network, where the ...
Anomalies and Vector Space Search: Tools for S-Box Reverse-Engineering
Reverse-engineering Vector space search BCT
2019/5/21
S-boxes are functions with an input so small that the simplest way to specify them is their lookup table (LUT). Unfortunately, some algorithm designers exploit this fact to avoid providing the algorit...
The Mersenne Low Hamming Combination Search Problem can be reduced to an ILP Problem
Post-Quantum Cryptography Cryptanalysis Public-Key Cryptography Integer Linear Programming
2019/5/13
In 2017, Aggarwal, Joux, Prakash, and Santha proposed an innovative NTRU-like public-key cryptosystem that was believed to be quantum resistant, based on Mersenne prime numbers q=2N−1q=2N−...
Full Database Reconstruction with Access and Search Pattern Leakage
Searchable Encryption Encrypted Databases Leakage-Abuse Attacks
2019/4/22
The widespread use of cloud computing has enabled several database providers to store their data on servers in the cloud and answer queries from those servers. In order to protect the confidentiality ...
We prove an Ω(dlgn/(lglgn)2)Ω(dlgn/(lglgn)2) lower bound on the dynamic cell-probe complexity of statistically obliviousoblivious approximate-near-neighbor search (ANNANN) over th...
SANNS: Scaling Up Secure Approximate k-Nearest Neighbors Search
nearest neighbor search privacy-preserving data analysis
2019/4/10
We present new secure protocols for approximate kk-nearest neighbor search (kk-NNS) over the Euclidean distance in the semi-honest model. Our implementation is able to handle massive datasets efficien...
Iterated Search Problems and Blockchain Security under Falsifiable Assumptions
blockchain protocols proof-of-work falsifiable assumptions
2019/4/1
We put forth a new class of search problems, iterated search problems (ISP), and study their relation to the design of secure blockchain protocols. We prove that (i) any blockchain protocol implies a ...
