Abstract This paper gives an introduction to elliptic curve cryptography (ECC) and how it is used in the implementation of digital signature (ECDSA) and key agreement (ECDH) Algorithms. The paper discusses the implementation of ECC on two finite fields‚ prime field and binary field. It also gives an overview of ECC implementation on different coordinate systems called the projective coordinate systems. The paper also discusses the basics of prime and binary field arithmetic. This paper also discusses

electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the acid dissolves the zinc freeing electrons. At the copper strip‚ the acid uses those electrons to form hydrogen gas. Because the zinc strip frees electrons and the copper strip uses electrons‚ if you put a wire between the two strips‚ then electrons will flow

the book Firms of Endearment (FoE) are calling present times as the “Age of Transcendence”. They suggest that today’s population wants more out of life than just material returns (p.xxxvii). People are looking towards self-realization and self-actualization more than ever. The authors build up enough evidence throughout the book to support on what they call the “stakeholder relationship management” (SRM) business model‚ that is based on Edward Freeman’s book (p.32). They clarify that this theory is

The Reconfiguration of Existing Product Technologies and the Failure of Established Firms Rebecca M. Henderson Massachusetts Institute of Technology Kim B. Clark Harvard University This paper demonstrates that the traditional categorization of innovation as either incremental or radical is incomplete and potentially misleading and does not account for the sometimes disastrous effects on industry incumbents of seemingly minor improvements in technological products. We examine such innovations more

In essence‚ its introduction reconceptualised what the business was about by converting a functional product into an emotional one. This in turn‚ increased the total pie of value available for the watchmaking industry; consumers now desired watches for both functional and fashionable purposes.

In this simulation you will see the analysis point out the effect of supply and demand and how it can and needs to reestablishment of price equilibrium

Critically analyse this reasoning. 6. List some ways in which consumers and firms might respond to a large increase in the price of oil. What effect would this have on the longer-term price of oil? 7. Answer all parts. a) Why do economists theorise rather than attempt to describe reality? b) Do assumptions

Explain how production possibility curves can be used to demonstrate the problem of unemployment‚ effects of technological change and the benefits of economic growth. Human wants are unlimited and resources are scarce. In order to satisfy these wants‚ all societies face the problem of allocating these scarce resources to producing the wanted products. These decisions greatly affect the economy and will contribute to the movements of growth. A graph that visually represents the results of the decisions
