Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Distributed sequential federated learning
分布式 联合学习 数据分析
2023/11/7
The analysis of data stored in multiple sites has become more popular, raising new concerns about the security of data storage and communication. Federated learning, which does not require centralizin...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Sequential Network Design
顺序 网络设计 局部互补性 博弈
2023/4/24
We study the problem of designing efficient network sequentially. In each period, the planner connects two unlinked agents in the network formed in previous periods, then the agents play a game with l...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bayesian sequential design for sensitivity experiments with hybrid responses
混合响应 灵敏度实验 贝叶斯顺序设计
2023/4/25
In experimental design, a common problem seen in practice is when the result includes one binary response and multiple continuous responses. However, this problem receives scant attention. Most studie...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Sequential implementation of reconstruction regression
重建回归 顺序实现 空间填充设计
2023/4/26
We propose a sequential method for implementing reconstruction regression. With a space-filling design of a small sample size, we use GP interpolation-based reconstruction regression to build initial ...
A proof of sequential work allows a prover to convince a verifier that a certain amount of sequential steps have been computed. In this work we introduce the notion of incremental proofs of sequential...
SAT-attack is known to successfully decrypt a functionally correct key of a locked combinational circuit. It is possible to extend the SAT-attack to sequential circuits through the scan-chain by selec...
Proofs of sequential work (PoSW) are proof systems where a prover, upon receiving a statement χχ and a time parameter TT computes a proof ϕ(χ,T)ϕ(χ,T) which is efficiently and publicly verif...
At ITCS 2013, Mahmoody, Moran and Vadhan [MMV'13] introduce and construct publicly verifiable proofs of sequential work, which is a protocol for proving that one spent sequential computational work re...
A Unified Framework for Trapdoor-Permutation-Based Sequential Aggregate Signatures
Aggregate signatures trapdoor permutations ideal cipher model
2018/1/19
We give a framework for trapdoor-permutation-based sequential aggregate signatures (SAS) that unifies and simplifies prior work and leads to new results. The framework is based on ideal ciphers over l...
Practical and Robust Secure Logging from Fault-Tolerant Sequential Aggregate Signatures
Sequential Aggregate Signatures Fault-Tolerance Secure Logging
2017/9/28
Keeping correct and informative log files is crucial for system maintenance, security and forensics. Cryptographic logging schemes offer integrity checks that protect a log file even in the case where...

Researchers DNA Sequential Consequential Building Mission
2017/7/21
A team of scientists has developed a method to create structures whose building blocks are a millionth of a meter in size by encoding DNA with assembly instructions.The work, described in the journal ...
A Generic Approach to Identity-based Sequential Aggregate Signatures: New constructions from 2-level HIBE Schemes
Identity-based Signatures Sequential Aggregate Signatures the CDH Assumption
2017/4/12
Identity-based sequential aggregate signature (IBSAS) schemes are usually applied to secure network routing and sensor networks, since they allow multiple signers to sequentially produce a short signa...
Sequential abiotic stress applied to juvenile eggplant modifies the seedlings parameters,plant ontogeny and yield
chilling cross-tolerance Solanum melongena stress memory yield
2016/9/2
The main goal of this study was to evaluate eggplant (Solanum melongena L.) susceptibility to a sequence of stress factors during plant ontogeny based on seedling morphological, biochemical and physio...

2016/5/30
Randomized Controlled Trials (RCTs) are currently the gold standard within evidence-based medicine. Usually, they are conducted as sequential trials allowing for monitoring for early signs of effectiv...
MQSAS - A Multivariate Sequential Aggregate Signature Scheme
Multivariate Cryptography HFEv- Sequential Aggregate Signatures
2016/5/24
(Sequential) Aggregate signature schemes enable a group of users u1,…,uk with messages m1,…,mk to produce a single signature Σ which states the integrity and authenticity of all the messages m1,…,mk. ...
