Cluster-based key management scheme for ad hoc networks by HU Rong-lei1 2, LIU Jian-wei2, ZHANG Qi-shan2

“…A new threshold key distribution scheme basing on self-certified public key and CPK（composite public key） technology was presented for ad hoc networks.Basing on the key distribution scheme and cluster networks structure,an integrated key management scheme was presented.The public key can be certified itself and so the certificate is not need in the scheme.The process of key distribution is simple and the key escrow problem existing in IBE（identity-based en-cryption） scheme is solved.The scheme can be used in different scale networks and can meet the dynamic topology of the ad hoc networks.The experimental results and theoretical analysis show that the overhead of computation and communi-cation is lower.Comparing with PKI and IBE scheme the scheme is more secure and practical.…”

Remarks on the Reasoning: The Morals of a Hungarian Expulsion Decision in Times of Pandemic by Erzsébet Csatlós

“… Several Iranian university students were expelled from Hungary to Iran due to their (allegedly) unlawful behaviour during their quarantine period at the outburst of the Covid-19 pandemic on grounds of being a threat to public policy and public security. The case reveals a worrisome practice in the reasoning of expulsion decisions, irrespective of the pandemic. …”

Optical fiber eavesdropping detection method based on machine learning by Xiaolian CHEN, Yi QIN, Jie ZHANG, Yajie LI, Haokun SONG, Huibin ZHANG

“…Optical fiber eavesdropping is one of the major hidden dangers of power grid information security,but detection is difficult due to its high concealment.Aiming at the eavesdropping problems faced by communication networks,an optical fiber eavesdropping detection method based on machine learning was proposed.Firstly,seven-dimensions feature vector extraction method was designed based on the influence of eavesdropping on the physical layer of transmission.Then eavesdropping was simulated and experimental feature vectors were collected.Finally,two machine learning algorithms were used for classification detection and model optimization.Experiments show that the performance of the neural network classification is better than the K-nearest neighbor classification,and it can achieve 98.1% eavesdropping recognition rate in 10% splitting ratio eavesdropping.…”

RBFT: a new Byzantine fault-tolerant consensus mechanism based on Raft cluster by Dongyan HUANG, Lang LI, Bin CHEN, Bo WANG

“…The existing consensus mechanisms of consortium blockchain are not scalable enough to provide low latency, high throughput and security while supporting large-scale network.A new consensus mechanism called RBFT was proposed to improve scalability, which was a two-level consensus mechanism with supervised nodes based on the idea of network fragmentation.In RBFT, the nodes were firstly divided into several groups.Each group adopted the improved Raft mechanism to reach consensus and select leader.Then, the leaders of each group formed the network committee, and the network committee adopted PBFT mechanism for consensus.Comparative experiments verify that RBFT can tolerant Byzantine fault while ensuring high consensus efficiency in large-scale network compared with PBFT and Raft.…”

A compressive data gathering method based on El Gamal cryptography by Xiaohan YU, Keming DONG, Xia LI, Chao CHEN

“…As a hot researching area,compressive sensing has advantages in signal process,image processing and data gathering and analysis.How to effectively and safely apply compressive sensing technology to collect data in wireless sensor networks is studied.Conventional compressive sensing technology based data collection method does not consider the security issue.Furthermore,every nod in the network must participate in the process of collecting measurements.The El Gamal cryptography and sparse matrices based compressive sensing technology were combined,and the El Gamal based sparse compressive data gathering (ESCDG) method was proposed.Theoretical analysis and numerical experiments show that ESCDG not only decreases the network resource consumption but also be able to defense the internal and external attacks.…”

Asymmetric watermarking based on Contourlet transform and subspace projection by HE Mi, CHENG Li-zhi

“…For the copyright protection of the digital image,a new asymmetric watermarking method of feature subspace projection based on Contourlet transform was presented.Embedding matrix（private key） and detecting matrix（public key） were constructed differently,where embedding matrix was kept secretly while detecting matrix was public.At the same time,the embedding matrix was independent on the host images.Robust subspace was obtained by Contourlet transformation.Using the embedding matrix,the arbitrary watermarking was embedded in the robust subspace.The de-tection function was constructed to detect whether an image had watermarking or not.The proposed method has good security,high detection probability and low false alarm probability.The stimulation shows that the proposed method is robust to many attacks.…”

GreyFan:a network attack framework using Wi-Fi covert channel by Dongjie MA, Chengqiang JIN, ·uan CHEN, Tieming CHEN

“…For traditional physical attacks such as side channel attacks and HID attacks in real networks,physical isolation is considered to be a relatively complete security protection against network attacks.In 2018,a Wi-Fi hidden channel method in the physical isolation environment——Ghost Tunnel was firstly proposed,that is,in the state that Wi-Fi didn’t connected,the wireless AP could successfully transmit data to the computer that initiates the connection request.An attack framework based on the Ghost Tunnel method——GreyFan was proposed.This attack framework enabled attackers to implement non-aware attacks on users who didn’t connected to Wi-Fi,such as file concealed transmission and arbitrary code execution,etc.The corresponding defense technology was also analyzed.…”

Dandiacal Conversation in Oscar Wilde’s Comedies of Manners: Conventions, Conversions and Reconfigurations of Phallogocentrism by Gilbert Pham-Thanh

“…Their strong reliance on rhetoric ensures their supremacy in polite conversation, even if their intellectual and cultural edge does a lot to secure their domination. What is more, their mastery of codes and norms enables them to destabilize the semantics of the age, a gesture which can be equated to a reconfiguration of Victorian patriarchy and even a dismissal of Victorian grand narratives.…”
