  • We now begin our look at building protocols using the basic tools that we have discussed. The discussion in this lecture will focus on issues of key establishment and the associated notion of authentication These protocols are not real, but instead are meant to serve just as a high-level survey Later lectures will go into specific protocols and will uncover practical challenges faced when implementing these protocols

  • The efficient generation of public-key parameters is a prerequisite in public-key systems. A specific example is the requirement of a prime number p to define a finite field Zp for use in the Diffie-Hellman key agreement protocol and its derivatives (x12.6). In this case, an element of high order in Z p is also required. Another example is the requirement of primes p and q for an RSA modulus n = pq (x8.2).

  • Another notable increase occurred in the forward-rate agreement (FRA) usage. FRA is a contract that determines the rate of interest, or currency exchange rate, to be paid or received on an obligation beginning at some future date. At the end of 1996, 9.02 percent of the sample banks report using FRAs. By the end of 2004, the percentage using FRAs more than doubled. While the percentage of banks participating in the swaps and forwards increased over the sample period, the proportion of banks using interest-rate options fell.

  • We have defined and described different types of PMO that exist across various organisations, the type of activity undertaken by these PMOs and the degree of influence they can have on key aspects of project, programme and portfolio management. To conclude, we would like to reinforce the fact that “Establishing a PMO is not a simple solution to a complex problem”. Having a PMO does not, by itself, increase project success.

  • In today’s knowledge-based global marketplace, human capital has replaced physical capital as the source of competitive advantage. A key result of the confluence of technology and the Internet Economy is the need for better, faster and smarter workers. The reality of a 4% unemployment rate in the U.S., the “free agent” mindset of the most talented workers, and the fact that only 21% of the U.S. adult population has a college degree is making this task more difficult than ever before.

  • PHC was not just a blueprint for organizing a public health system. It was a fundamental approach to health itself, which included key values: services to be delivered as close to the community as possible, in a system that the country could afford, in an integrated manner, with the participation of the community. Health was understood in its full social and economic dimensions and health care was understood as an essential part of what good governance should mean. These were optimistic times: the commitment to PHC and to “Health for All by the Year...
