Database management system has become a part and parcel of the present corporate business ranging from ecommerce, retail chains, data mining and warehousing application etc. This paper deals with a lucid mathematical model for evaluating the average response time for queries in DBMS (DataBase Management System). Response time is one of the key metrics for ...

In this paper, the authors present a peer analysis in the field of encryption algorithms, in concentrating on private key block ciphers which are generally used for bulk data and link encryption. They have initially survey some of the more popular and efficient algorithms currently in use. This paper focuses mainly on the different kinds ...

In cloud, scaling is the ability to provide the services without lagging performance, in case of increased or decreased load. The system should be able to adapt to the customer request so as to increase resources or decrease the resources, so as to maintain the balance between performance and cost effectiveness. For scaling the application ...

Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a public and private key pair from a certificate authority. Any other user who wants to send an encrypted message can get the intended ...

In present world Software Defined Networks (SDNs) are setting new definitions of high speed and advance networking. These networks are growing very efficiently and spreading their popularity in industry as well as in research and development. There is a wide range of scope in this kind of advanced network from security point of view. In ...

Security of Information is one of the cornerstones of Information Society. As number of Network attacks have increased over the past few years, Intrusion Detection System (IDS) is increasingly becoming a critical component to protect the network. In recent years, many researchers are using data mining techniques for building IDS. One of the main challenges ...

Signature has always been and still is widely used as a validation tool to identify the user or their intent in civil society. Online signature is nothing but the dynamic process of handwriting as a feature vector sequence along time. Dynamic Time Warping (DTW) has been used as a popular method to compare sequence data. ...

Consumerization of IT or Bring Your Own Device (BYOD) concept is spreading very quickly in the organizations which hugely depend on IT infrastructure and need their employees connected to the organizations computer network for most of their tasks. Simply stating, BYOD means allowing employees to access organization network via their own devices/technology. This has resulted ...

In this approach, only the information about a previous value of a dimension is written into the database. An ‘Old ‘or ‘Previous’ column is created which stores the immediate previous attribute. The problem with this approach is over years, if the product price continuously changes, then the complete history may not be stored, only the ...

High speed and low power MAC unit is utmost requirement of today’s VLSI systems and digital signal processing applications like FFT, finite impulse response filters, convolution etc. In this paper, the authors have discussed different types of multipliers like booth multiplier, combinational multiplier, Wallace tree multiplier, array multiplier and sequential multiplier. Each multiplier has its ...
