Analysis of the Security of BB84 by Model Checking

Quantum Cryptography or Quantum key distribution (QKD) is a technique that allows the secure distribution of a bit string, used as key in cryptographic protocols. When it was noted that quantum computers could break public key cryptosystems based on number theory extensive studies have been undertaken on QKD. Based on quantum mechanics, QKD offers unconditionally secure communication. Now, the progress of research in this field allows the anticipation of QKD to be available outside of laboratories within the next few years. Efforts are made to improve the performance and reliability of the implemented technologies. But several challenges remain despite this big progress. The task of how to test the apparatuses of QKD For example did not yet receive enough attention. These devises become complex and demand a big verification effort. In this paper we are interested in an approach based on the technique of probabilistic model checking for studying quantum information. Precisely, we use the PRISM tool to analyze the security of BB84 protocol and we are focused on the specific security property of eavesdropping detection. We show that this property is affected by the parameters of quantum channel and the power of eavesdropper.Comment: 12 Pages, IJNS

Cultivating Critical Thinking Skill In Teaching And Learning And Learning Process

The purpose of this article is to spearhead two objectives namely, to fulfill my assignment and to help our future leaders that are our beloved student to analyze multilogical problem of contemporary in teaching and learning process . Those problem that can be viewed holistically from the top or bird eyes perspective thus manages them using correct tool and try solve from many different angles. Joanne Kurfiss simply define critical as “ An investigation whose reason is to explore problem to arrive at the hypothesis that integrate all available information convincingly justified. It is a self regulatory which result in interpretation, analysis, evaluation and inference as well as explanation of evidence, conceptual, methodological or conceptual consideration upon which the judgment is base

Self Concepts and Motivation To Learn Among Students

Abtract: In Malaysia, more than half of the population are adolescent and most of them are students who are still studiying either in schools or in higher institutions of learning. We should be proud that eventhough there is no punishment to enforce education , 99 percent of the schooloing age children are getting their education. Wether they are willing to learn or reach level depend on many factors. For now, most of the students learn just to pass their exam and not learning continuosly through life as we hope for. Is it because the students are not motivated to learn because of their negative self concept ? or is it the teachers and parents who cause the students not to be motivated and encouraged to learn and excelled , what more to compete in education? The answer lies in all the significant people who should play their role in developing positive self concept to motivate students to learn

Aspects of social identity, self concept, self esteem, self functioning and gender aspects (part 4)

Formation of self concept begins in childhood and it continues throughout an individual’s life. Like Eric Erikson says in his „Eight stages of development‟, an individual goes through eight stages in his life

Accounting information system: Education and research agenda

Revolution of information technology has changed many aspects of accounting practices, which resulted in greater demand for accountants with sufficient information technology (IT) knowledge and skills. Importantly, these changes have provided new and exciting research opportunities for accounting information system (AIS) researchers. This paper aims to address issues relating to both AIS education and research. It also attempts to provide guidance to AIS curriculum design and direction for AIS research. In terms of AIS education, this paper reveal that accounting programmes worldwide have not sufficiently integrated IT knowledge and skills into the curriculum, thus resulting in the inability to produce graduates that meet the current needs of businesses. In terms of research, the paper starts with a discussion on issues relating to definition, scope and category of AIS research. In general, while IT revolution has offered various research opportunities, AIS research has provided very limited contribution to accounting or information system research and practice. Towards this purpose, this paper provides several suggestions to researchers. First, AIS researchers need to view AIS in a broader perspective where the impact of technology on all areas of accounting, auditing, and taxation should be considered within the realm of AIS interest. Second, AIS researchers have to specialise in at least one other accounting area such as financial reporting, managerial accounting, audit or taxation, in addition to AIS domain, to produce high-quality research results. Finally, it is hoped that discussions brought forward by this paper would initiate and encourage debate among accounting professionals and academics and, in particular AIS lecturers, in order to strengthen current AIS curriculum to produce high-quality AIS research that can have a notable impact on the accounting profession and business practice

Radiative transition of negative to positive parity nucleon

We investigate the $N^{\ast}(1535)\rightarrow N\gamma$ transition in the framework of light cone QCD sum rules. In particular, using the most general form of the interpolating current for the nucleon as well as the distribution amplitudes of the photon, we calculate two transition form factors responsible for this channel and use them to evaluate the decay width and branching ratio of the transition under consideration. The result obtained for the branching fraction is in a good consistency with the experimental data.Comment: A typo has been correcte
