Example Sentences
Recent Examples on the Web Since the 1970s, the RSA cryptosystem, which uses very large prime numbers to create public keys that serve as the basis of the security protocol for data communicated between Internet applications, has proven to be relatively effective. 
Vinit Patel, Fortune, 1 July 2022 Although Peter Shor of Bell Labs published a paper in 1994 showing that a quantum algorithm could crack the RSA cryptosystem, machines that can run such an algorithm haven’t been developed—yet. Vinit Patel, Fortune, 1 July 2022 Conti also appeared to drum up ideas for a cryptosystem by holding a competition on a hacker forum, as first reported by investigative journalist Brian Krebs. Matt Burgess, Wired, 17 Mar. 2022 The Danish sugar beet auction established the feasibility of a cryptosystem that could manage both computation and private inputs. Kazuhiro Gomi, Forbes, 26 Oct. 2021 So why is the internet still overleveraging a cryptosystem that is coming up on 45 years old? Lila Kee, Forbes, 6 May 2021 Obviously, this would be another potentially catastrophic touch point to have your cryptosystem fail you. Lila Kee, Forbes, 6 May 2021 The issues relate to RSA, the ubiquitous encryption algorithm and cryptosystem that helps protect everything from web browsers and VPNs to email and messaging applications. Lily Hay Newman, WIRED, 7 Aug. 2019 If researchers could build a quantum computer that could outperform classical supercomputers, the thinking goes, cryptographers could use a particular algorithm called Shor’s algorithm to render the RSA cryptosystem unsalvageable.
