The Handshake as Non‐verbal Communication in Business

Abstract: The first thing you do when you meet someone in a business context is to tell that person who you think you are, who you think they are, and what you think the nature of your relationship is going to be. Explores some of the issues which surround the handshake in a business setting and discusses some of the characteristics and meanings of handshakes, with special attention to gender and cultural differences. The argument is made that, if there is a problem in the workplace for uninitiated, untrained persons with handshaking, it would be worthwhile addressing communication skill in an educational setting.

Detection of Tor Traffic Hiding Under Obfs4 Protocol Based on Two-Level Filtering

Abstract: Tor (The second generation Onion Router) is the most popular anonymous communication network. In order to protect Tor user from traffic analysis attack, many obfuscation techniques are adopted and Obfs4 is one of the states of art techniques used in Tor. It is very hard to detect the Tor traffic camouflaged under Obfs4, especially in the real world when there is a large volume of various traffic, because of random padding and randomization of time sequence. In this paper, we propose a novel scheme for Obfs4 traffic detection based on two-level filtering. We sequentially utilize coarse-grained fast filtering and fine-grained accurate identification to achieve high-precision, real-time recognition of Obfs4 traffic. In the coarse-grained filtering phase, we use the randomness detection algorithm to detect the randomness of the handshake packet payload in the communication and use the timing sequence characteristics of the packet in the handshake process to remove other interference traffic. In the fine-grained identification phase, we analyze its statistical feature on a large number of Obfs4 traffic and use the classification algorithms to identify the Obfs4 traffic. We train and test with different classifiers. The experiments show that the accuracy for identifying Obfs4 is above 99% when using the SVM (Support Vector Machine) algorithm, which indicates that Obfs4 cannot effectively counteract traffic analysis attacks in practical applications.

Handshake Logic-Based Event-Triggered Load Frequency Control for Smart Grids Under DoS Attacks

Abstract: This article investigates the load frequency control (LFC) problem for smart grids with denial-of-service (DoS) attacks via a novel event-triggered control method. In order to sustain the stable operation of the smart grids, a handshake logic-based event-triggered communication scheme is proposed. The targets of the designed controller are twofold. First, an event-triggered mechanism with a handshake logic-based concept is proposed to save network resources. In this triggering method, a handshake protocol is used to detect DoS attacks in the communication networks. Second, by employing Lyapunov stability theory, sufficient stabilization criteria ensuring the uncertain LFC systems being asymptotically stable are deduced. Based on these conditions, the corresponding state-feedback controller design method is given. Finally, a simulation of a two-area power system with electric vehicles is given as an example to substantiate the proposed method of this article.

Handshake protocol using return-to-zero data encoding for high performance asynchronous bus

Abstract: In SoC design, synchronous buses are used frequently to interconnect several IPs. However, it is difficult to use synchronous buses for SoC design because of the increase of wire delay caused by the crosstalk effect and the difficulty of synchronisation caused by the clock-skew problem. The use of an asynchronous bus is an alternative solution for SoC design methodology. A new handshake protocol is proposed using the return-to-zero data encoding scheme for the implementation of a new high performance asynchronous bus. Simulation results reveal that the proposed handshake protocol increases the read throughput of the asynchronous bus by 30.5%, and decreases the read latency by 12.5%.

Method and system for automatic language negotiation on voice (over IP) calls

Abstract: A method for negotiating a common language on a voice over Internet Protocol (VoIP) network, the method comprising: allowing a plurality of users to connect to the VoIP network, each of the plurality of users having at least one of a plurality of VoIP compatible transmitting/receiving devices; configuring each of the plurality of VoIP compatible transmitting/receiving devices with a list of a plurality of languages, each of the plurality of languages having a priority level associated therewith; allowing automatic selection of the common language between two or more of the plurality of users on a joint VoIP call by performing a language handshake; computing a maximum selection score via a language handshake algorithm provided by the language handshake; maximizing a sum of priority levels; minimizing a sum of priority differences; and selecting the common language that provides a largest sum of the priority levels and a lowest sum of the priority differences.
