The author suggests that the teaching of mathematics and science in K-12 schools be outsourced to teachers in other countries whose students achieve better in mathematics and science. He outlines the advantages of using telecommunications technologies to outsource the teaching of mathematics and science.

This paper describes the Elliptic Curve Cryptography algorithm and its suitability for smart cards.

Much contemporary talk of virtual 'worlds' proceeds as if the virtual could somehow be considered as in competition with or as an alternative to the world of the 'nonvirtual' or the 'everyday'. This paper argues that such a contrast is fundamentally mistaken, and that the virtual is not autonomous with respect to the everyday, but is rather embedded within it, and an extension of it.

In E-Commerce credit cards gained popularity as a sophisticated payment mechanism. With the increase in credit card use on web, credit card fraud has gone up dramatically. Which cause customer's inconvenience and for merchant, loss of customers. To combat credit card fraud and to regain the customer's trust an attempt is made here to design a trust based payment system, in which the customer does not need to disclose his/her credit card number during the transaction, and hence they can feel safe. In this newly proposed system on behalf of the customer the bank or the issuer of the credit card is involved to perform the transaction. This is basically done by generating a single use 'token' by the bank which includes information about the customer, merchant, product, payment amount, date of issue and date of expiry etc. and thereafter wrapped as a DRM package. Among various advantages, one is that only the intended user and the specified application software can open the DRM package using special key. The application, thereafter, will take care of the rights imposed on the 'token' and expires itself after the single use. We have tried an attempt to use UML to design the model of such system, which is the recent trend of software engineering practice.

During the course to deploy Ipv6, we found several critical implementation and operational issues which distract user and possibly prevent wide deployment of Ipv6. Among the problems we noticed stateless IP autoconfiguration, which provides for each nodes connected to the network an IP address. However, two nodes may have the same address, and a network conflict appears. In this case a manual IP address, which depends on restarting Network Interface Card, is required. In this paper, we present a technique that, independently of rebooting NIC, maintain the IP address fix. Validation is done by using Fedoracore Operating System.
