6、大学 Construction of binary sequences with low correlation 金玲飞 复旦大学 Binary sequences with good correlation property have many applications, such as wireless communication and cryptography. Gold sequence is a type of pseudo-random sequence and plays a crucial role in telecommunication and satellite nav。
7、igation. In literature, there are several methods to construct Gold sequences. One of the constructions is via the trace function from extension field of F2. In this talk, we generalize this construction from finite fields of even characteristic to odd characteristics by using multiplicative quadrat。
8、ic character. Thus, we obtain binary sequences which have more flexibility on length while still possessing low correlation property. List Decoding of Insertion and Deletion Codes 刘姝 电子科技大学 We consider the list decoding property of codes under insertion and deletion errors (insdel for short). Firstl。
9、y, we analyse the list decodability of random insdel codes. Our result provides a more complete picture on the list decodability of insdel codes when both insertion and deletion errors happen. Secondly, we construct a family of insdel codes along with their efficient encoding and decoding algorithms。
10、 through concatenation method which provides a Zyablov-type bound for insdel metric codes. A Systematic Approach and Analysis of Key Mismatch Attacks on Lattice-Based NIST Candidate KEMs 潘彦斌 中国科学院大学 Research on key mismatch attacks against lattice-based KEMs is an important part of the cryptographic。
11、 assessment of the ongoing NIST standardization of post-quantum cryptography. There have been a number of these attacks to date. However, a unified method to evaluate these KEMs resilience under key mismatch attacks is still missing. Since the key index of efficiency is the number of queries needed 。
12、to successfully mount such an attack, in this paper, we propose and develop a systematic approach to find lower bounds on the minimum average number of queries needed for such attacks. Our basic idea is to transform the problem of finding the lower bound of queries into finding an optimal binary rec。
13、overy tree (BRT), where the computations of the lower bounds become essentially the computations of a certain Shannon entropy. The optimal BRT approach also enables us to understand why, for some lattice-based NIST candidate KEMs, there is a big gap between the theoretical bounds and bounds observed。
14、 in practical attacks, in terms of the number of queries needed. This further leads us to propose a generic improvement method for these existing attacks, which are confirmed by our experiments. Moreover, our proposed method could be directly used to improve the side-channel attacks against CCA-secu。
15、re NIST candidate KEMs. Turan-type Problems for Sparse Hypergraphs 上官冲 山东大学 The notion of sparse hypergraphs was introduced by Brown, ErdHos and Sos in the 1970s. Since then, it has received considerable attention and has been repeatedly studied by various combinatorists. In this talk, I will survey。
16、 important problems and results in this field, and introduce our recent work. 无线物理层安全：困境与超越 孙黎 华为技术有限公司 无线物理层安全在过去的十几年里一直受到学术界的广泛关注，但始终没有在工 业界得到落地应用。这一方面缘于物理层安全技术的应用场景不够清晰，但更重要的 是，物理层安全在理论方面存在诸多不完备之处，许多关键问题有待回答。例如：物 理层安全技术的安全性如何科学度量？物理层密钥的随机熵如何准确评估？在通信物 理层实现安全的根本前提是什么？逼近一次一密的程度如何刻画？等等。本报告将指 出并尝试回答物理层安全研究中的若干重要基础问题，此外，还将基于工业界的视 角，介绍物理层安全。
