During the last decade, there has been a huge increase in the volume of Internet business transactions which in turn led to the emergence of a new field of scientific research ­ agent­based computational economics. In order to be able to conduct successful transactions, agents must have appropriate strategies to participate in trading negotiations. This paper i...

Modern Internet services often achieve scalability and availability by relying on large-scale distributed databases that provide consistency models for transactions weaker than serialisability. We investigate the classical problem of transaction chopping for a promising consistency model in this class—parallel snapshot isolation (PSI), which weakens the classical snapshot isolation to allow mor...

This paper argues that the whole company, and the market in which it operates, can be regarded as a series of linkages and relationships, and the company’s operating efficiency can be seen to depend upon how well these connections work. It notes that if the system can be made to flow smoothly, at minimum cost, than the chances are that the overall company performance, measured by any criteria, ...

Smart cards are an old breed of ubiquitous embedded-computing devices that are increasingly gaining popularity for electronic business transactions. When these smart cards are used over networks that can be covertly snooped, such as the Internet, there is a potential threat to the security of these transactions. In this report, I describe and analyze security models for smart cards that are use...

As Internet business exponentially grows, the need for high security level categories to identify groups of connections or individual transactions is manifest. The development of an efficient and secure communication protocol seems to be highly demanding. In this paper, we propose Adaptive Secure Protocol to support secure ecommerce transactions. Our Adaptive Secure Protocol dynamically adapts ...

Today, new technologies that allow cellular (mobile) phones and other handheld devices to access the Internet have made wireless business transactions possible. This phenomenon is known as mobile commerce or M-Commerce. What must be done to secure financial transactions via mobile commerce? Due to the advent of the Internet, electronic business transactions have exploded around the globe. Gener...

Branchless banking is making transaction without visiting a formal banking system. It includes; internet, SMS banking, mobile banking, ATM’s, POS and EFTPOS. Mobile banking has become the future of formal banking system. Hawala is an informal, traditional system for financial transactions in which no money actually enters in bank; all transactions are based on trust among the parties. In Pakist...

Secure socket layer (SSL) is the most popular protocol used in the Internet for facilitating secure communications. In this paper, we analyze the performance and architectural impact of SSL on the servers in terms of various parameters such as throughput, utilization, cache sizes, cache miss ratios, number of processors, control dependencies, le access sizes, bus transactions, network load, etc...
