The server encrypts each file before staging it on the surrogate. To handle a cache miss at the remote site, the client fetches the data from the surrogate, decrypts it, verifies its fingerprint and then uses the data. The volume of cached keys can be reduced by using a single private encryption key for all files, at the price of total exposure if that key is broken. (p.2)."
The author concludes the article with mention of the Aura Project at Carnegie Mellon, an initiative which is aimed at defined distraction-free, ubiquitous computing and support for nomadic access using the Coda File System, which has recently been updated to support efficient update propagation over low-bandwidth networks [3]. Aura is a commonly referenced concept in much of the cyber foraging literature, and supports the concept of increasingly complex content taxonomies being synchronized with applications and data sources through the use of data staging servers.

The role of trust and is quantification is raises as research question in the How does one establish an appropriate level of trust in a surrogate? What are useful levels of trust in practice? How applicable and useful is the concept of caching trust (Satyanarayanan article quoted previously is source) Can one amortize the cost of establishing trust across many surrogates in a neighborhood? (p.2)." Satyanarayanan's work is evident in this article as the authors collectively respond to the question with the following statement: "Can an untrusted computer facilitate secure mobile data access? Surprisingly, the answer is "yes." Data staging enables untrusted, unmanaged computers to be used to improve the performance of cache miss handling in an Internet-wide distributed file system. The untrusted computer, called a surrogate, plays the role of a second-level file cache for a mobile client. By proactively staging data on the surrogate, cache misses from a nearby mobile client can be serviced at low latency (typically one wireless hop) instead of full Internet latency (p.2)."

Peel does not critique explicitly the implicit violence within capitalism, as these authors do with respect to racism and economic exploitation, nor does he do a good job of placing the economic context of suburban Australian poverty with a global or colonialist perspective as he could have by emphasizing less the positive aspects of multiculturalism and more the negative aspects of cultural stigmatism within capitalism. At the same time,
Business cluster refers to the geographical concentration of closely related businesses, suppliers, and firms belonging in a given field. The primary objective of forming these clusters is to boost the productivity with which firms compete at both national and international levels. Clusters are also crucial in the strategic management processes. This article discusses the benefits of such clusters, the management at domestic and international scales, and the negative aspects of
Supply Chain Management and Concentrated Clusters Distribution Systems Author's Notes Concentrated Clusters and Improvement in Supply Chain Management and firm's overall performance Clusters are geographic concentrations which comprise of interconnected organizations or associations that manufacture products or deliver a service to a particular industry or field. Clusters are mainly a mix of companies belonging to the same industry or located in the same technological facility sharing resources like infrastructure, suppliers and distribution networks. It
highly legal enforcement through written contracts and covenants. Japanese channel relationships then take a much more longer-term perspective of change and growth, and rely more on indirect and often informal means of communication vs. formalized approaches. While to a westerner the Japanese distribution channels appear to be quite inefficient, the building of ownership of initiatives that eventually permeate a distribution channel makes execution of strategies much more efficient through
In this regard, some exceptions have been given to the insurance companies while the other companies should follow these principles. In the year 2005, the commercial sector of the United Kingdom spent $16,500 million for fossil fuels of 350,000 GWh. On the other hand, researchers have reported that a decline of energy consumption has been observed in the tertiary sector of the United Kingdom (Probst & Roecker, 2011, pg 109-124). Hot
In the older forms, people could live and work in relative independence if they disengaged from politics. Under a modern totalitarian government, people are completely and utterly dependent on, and submissive to, the rule and whims of a political party and its leaders. Older forms of such a government ruled by divine right, while the modern totalitarian state is ruled and run by a dictator who controls a political
