Standards and Practical Security Concerns
For applications where devices may fall into the physical possession of an adversary, protection against power analysis is generally a major design requirement. For example, FIPS 140-3 requires power analysis countermeasures for cryptographic devices bought to the U.S. government. Power analysis have also been reportedly used against conditional access modules used in pay television systems.
The equipment necessary for performing power analysis attacks is widely available. For example, most digital storage oscilloscopes provide the necessary data collection functionality, and the data analysis is typically performed using conventional PCs. Commercial products designed for testing labs are also available.

Famous quotes containing the words standards and, standards, practical, security and/or concerns:
“In full view of his television audience, he preached a new religion—or a new form of Christianity—based on faith in financial miracles and in a Heaven here on earth with a water slide and luxury hotels. It was a religion of celebrity and showmanship and fun, which made a mockery of all puritanical standards and all canons of good taste. Its standard was excess, and its doctrines were tolerance and freedom from accountability.”
—New Yorker (April 23, 1990)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
“Wisdom is not just knowing fundamental truths, if these are unconnected with the guidance of life or with a perspective on its meaning. If the deep truths physicists describe about the origin and functioning of the universe have little practical import and do not change our picture of the meaning of the universe and our place within it, then knowing them would not count as wisdom.”
—Robert Nozick (b. 1938)
“The horror of class stratification, racism, and prejudice is that some people begin to believe that the security of their families and communities depends on the oppression of others, that for some to have good lives there must be others whose lives are truncated and brutal.”
—Dorothy Allison (b. 1949)
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
