量子计算行业教育的发展

2020年，欧洲战略咨询委员会的量子旗舰计划成员正式向欧盟委员会提交了战略研究议程，提倡全欧推广覆盖高中教育、大学教育和产业工人培训的量子教育项目。国内外类似的量子教育措施正不断涌现，给中国量子教育的发展提供了一定的参考。文章主要对量子计算、量子教育行业的发展、量子教学工具的现状等内容进行了综述性梳理，试图探寻目前量子计算行业教育发展的困境，以期为推进中国量子计算教育寻找思路。     

SemTrust ： A Semantic Reputation System in P2P.Based Semantic Web

0 IntroductionThe goal of Semantic Webis to build a web of meaning.Semantic Web will consist of a distributed environmentof shared andinteroperable ontologies ,which have emerged ascommonformalisms for knowledge representation.It is prom-isingto combine P2P networks with Semantic Web technolo-gy. On one hand,P2P networks can help semantic web withsharing knowledge;onthe other hand,P2P networks use thesemantic concept to query routing and efficient content-basedlocation. However ,evenafter…     

Web Voice Browser Based on an ISLPC Text.to.Speech Algorithm

A kind of Web voice browser based on improved synchronous linear predictive coding （ISLPC） and Text-toSpeech （TTS） algorithm and Internet application was proposed. The paper analyzes the features of TTS system with ISLPC speech synthesis and discusses the design and implementation of ISLPC TTS-based Web voice browser. The browser integrates Web technology, Chinese information processing, artificial intelligence and the key technology of Chinese ISLPC speech synthesis. It＇s a visual and audible web browser that can improve information precision for network users. The evaluation results show that ISLPC-based TTS model has a better performance than other browsers in voice quality and capability of identifying Chinese characters.

A Robust IP Packets Filtering Mechanism for Protecting Web Server from DDoS Attacks

Distributed denial of service （DDoS） attacks exploit the availability of Web servers, resulting in the severe loss of their connectivity. We present a robust IP packets filtering mechanism which combines the detection and filtering engine together to protect Web Servers from DDoS Attacks. The mechanism can detect DDoS attacks by inspecting inbound packets with an IP address database, and filter out lower priority IP addresses to preserve the connection for valid users by monitoring the queues status. We use the Netfilter＇s technique, a framework inside the Linux 2.4. X, to implement it on a Web server. Also, we evaluate this mechanism and analyze the influence of some important parameters on system performance. The experimental results show that this mechanism is effective against DDoS attacks.     

Merkle Tree Digital Signature and Trusted Computing Platform

0 IntroductionDigital signatureis a key technique to provide datainteg-rity andsource authenticationcapabilities to enhance da-ta trustworthiness in trusted computing platform. Most cur-rent digital signature schemes are based on complex mathe-matical problems , such as integer factoring, discrete log-arithm,and discrete logarithm on elliptic curves . The hard-ness of these underlying mathematical problems is really un-certain at present . Merkle treeis a method used for authenti-cation and di…

Linguistic Truth Values Lattice Implication Algebras

In order to study uncertainty reasoning and automatic reasoning with linguistic terms, in this paper, the set of basic linguistic truth values and the set of modifiers are defined, according to common sense; partially orderings are defined on them. Based on it, a lattice implication algebra model L18 of linguistic terms is built; furthermore, its some basic properties are discussed.
