In qualitative research, a member check, also known as informant feedback or respondent validation, is a technique used by researchers to help improve the accuracy, credibility, validity, and transferability (also known as applicability, internal validity, [1] or fittingness) of a study. [2]
The NSA considered various options, including writing a negative review of Kahn's work to be published in the press to discredit him. [ 4 ] A committee of the United States Intelligence Board concluded that the book was "a possibly valuable support to foreign COMSEC authorities" and recommended "further low-key actions as possible, but short of ...
Inspection is a verification method that is used to compare how correctly the conceptual model matches the executable model. Teams of experts, developers, and testers will thoroughly scan the content (algorithms, programming code, documents, equations) in the original conceptual model and compare with the appropriate counterpart to verify how closely the executable model matches.

Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results. In ...

David Kahn was born in New York City to Florence Abraham Kahn, a glass manufacturer, and Jesse Kahn, a lawyer, and grew up in Great Neck, NY on Long Island. [2] Kahn said he traced his interest in cryptography to reading Fletcher Pratt's Secret and Urgent (1939) as a boy. [2] Kahn was a founding editor of the Cryptologia journal.
Another approach is deductive verification. [5] [6] It consists of generating from the system and its specifications (and possibly other annotations) a collection of mathematical proof obligations, the truth of which imply conformance of the system to its specification, and discharging these obligations using either proof assistants (interactive theorem provers) (such as HOL, ACL2, Isabelle ...
Peggy and Victor agree on a prime p and a generator of the multiplicative group of the field ℤ p. Peggy calculates the value y = g x mod p and transfers the value to Victor. The following two steps are repeated a (large) number of times. Peggy repeatedly picks a random value r ∈ U[0, p − 2] and calculates C = g r mod p.
