Extreme Programming (XP) is a software engineering methodology that has been formulated in 1996 by Kent Beck. It is a lightweight development methodology, XP is one of several popular agile processes. Extreme Programming has received fair media attention, and is most renowned for its practices that are sometimes regarded as controversial, such as pair programming and test-driven development. It has already been proven to be very successful because it reaches to the customer satisfaction. Instead of delivering everything at the same time the XP focus on some date far in the future, this process delivers the software you need as you need it, in other words Extreme Programming empowers the developers to confidently respond to changing customer requirements, even late in the project development life cycle. The philosophy of Extreme Programming is teamwork, in other words Managers, Customers and Developers are all equal partners in a collaborative team. The implement Continue reading

An Introduction to Cryptography and Digital Signatures
Cryptography The Greek words “krypt ´os” standing for “hidden” and the word “l ´ogos” that means “word”, are in essence the base from where the word cryptology was derived. As these words denote, cryptology can be best explained by the meaning “hidden word”. In this context, the original purpose behind cryptology is hiding the meaning of some specific combination of words which in turn would insure secrecy and confidentiality. This is a very limited viewpoint in today’s perspective and a wide range of security applications and issues now come under the term of cryptology (rest of the portion of this section will clarify this point of view). As field of mathematical science, Cryptology includes the study of both cryptanalysis as well as cryptography. On one hand, cryptography is a very broad term and represents any process used for data protection. On the other hand, the study of security related issues Continue reading

eGovernment – Definitions and Benefits
EGovernment is one more of the recent years “buzzwords”. It is usually either paired with the word “services” at the end or other words like eGovernance and Digital Government. Like every other (relatively) new and cool “buzzword” they are used widely by a broad spectrum of individuals who represent mostly two different backgrounds. Information technology and politics. The first because it is a technological issue, the later because they have come to realize, even though a little late, that they represent an excellent vehicle for them to provide a better experience to anyone who interacts with the Government. But, what do these terms mean? Do they collide or conflict each other? How about covering or including one another? EGovernment is in the first stages of development. Most governments have already taken or are taking initiatives offering government services online. However, for the true potential of eGovernment to be realized, government Continue reading

Introduction to Radio Frequency Identification (RFID)
In past few recent years, the automatic identification techniques have become quite more than popular and they have also find their places into the core of service industries, manufacturing companies, aviation, clothing, transport systems and much more. And, it’s pretty clear by this point of time that the automated identification technology especially RFID, is highly helpful in providing information regarding the timings, location and even more intense information about people, animals, goods etc. in transit. RFID is responsible for storage of large amount of data and is reprogrammable also as in contrast with its counterpart barcodes automatic identification technology. In everyday life, the most common form of an electronic data-carrying device if often a smartcard which is probably based upon the contact field. But, this kind of a contact oriented card is normally impractical and less flexible to use. On the contrary, if we think of a contactless card with Continue reading
