A New Symmetric key Cryptographic Algorithm for Unicode Compliant Bangla Characters
(East West University, 1/1/2007) Sarker, Md. Zakir Hossain; Rahman, Shaila; Rahman, M Lutfar
Cryptography is the discipline that embodies principles, means, and methods for the transformation of data in order to hide its information content, prevent its undetected modification and/or prevent its unauthorized use. Now-a-day most of the organizations are increasingly dependent on electronic data for various purposes. Since data travels electronically the alarming issue is the security. Cryptographic algorithms can play vital role to resolve this issue. There are two basic types of cryptography: secret/symmetric key and public/asymmetric key. Symmetric key algorithms are the quickest and most commonly used type of encryption. Here, a single key is used for both encryption and decryption. This paper describes a new symmetric key algorithm which is applied on the Unicode compliant bangle characters. Algorithms for both also described along with the drawbacks. Since government of Bangladesh is planning to introduce e-governance this kind of cryptographic algorithm should be applied to secure various important and vital data. As per as literature are concerned, this kind of work for Unicode compliant bangle characters has not been done yet i.e. this could be the pioneer work.
Potential Benefits and Pitfalls of IT Outsourcing from the viewpoint of Developed countries: Opportunities and Challenges for Bangladesh
(East West University, 1/1/2010) Sarker, Md. Zakir Hossain; Rahman, Shaila
Outsourcing generally refers to the practice of farming out jobs from the home base to other countries, largely in an effort to cut costs. Software developers are among an increasing number of companies turning to outsourcing as a strategy to improve cost control, product quality, product development schedule reduction, and focus on core business activities. As IT outsourcing becomes ever more ubiquitous across the globe, corporations are taking a closer look at the scope, quality, and nature of their outsourcing agreements. By 2015, analysts predict that more than 3 million white-collar jobs in the U.S. will be farmed out to other countries, up from about 300,000 today. If that shift is inevitable, the next question becomes which countries offer the best choice. Here, in this paper some guidelines have been provided to get the answer. Several years ago, software was identified by the government of Bangladesh as having important export potential and the IT industry was declared as a thrust sector. Human resources for the IT industry have also been growing rapidly. Considering all the factors involved, this paper concludes that Bangladesh could become on of the most competitive It outsource centers for the entire first world. This paper also discusses the opportunities and challenges for Bangladesh in becoming a successful IT outsourcing country.
