Dan Goodin, Ars Technica, 21 June 2022 Its adept mix of cryptanalysis, reverse engineering, and exploit development punches a major hole in defenses that Thunderbolt creator Intel spent considerable time and resources to erect. Dan Goodin, Ars Technica, 12 May 2020 WebAssembly proposes to change this, with native support for 64-bit integers, load-and-store offsets, and direct access to CPU instructions frequently used for specific tasks such as cryptanalysis. Jim Salter, Ars Technica, 14 Nov. 2019 There has been a great deal of work in mathematics and cryptanalysis around the RSA algorithm's use of primes. Sean Gallagher, Ars Technica, 29 Aug. 2019 Apart from the everyday women who broke new ground in the field of cryptanalysis, there are a few women whose absence from our nation’s historical memory is even more egregious. Liza Mundy, Smithsonian, 1 Mar. 2018 Her groundbreaking cryptanalytic work during and before World War II saved countless lives and immeasurably advanced the field of cryptanalysis, or codebreaking, and with it the science of encryption and cybersecurity. Liza Mundy, Slate Magazine, 10 Oct. 2017 Turing was somewhat dismissive of US cryptanalysis, believing the Americans to rely too heavily on machinery instead of thought.
