computationally secure cipher
21Key Wrap — constructions are a class of symmetric encryption algorithms designed to encapsulate (encrypt) cryptographic key material. The Key Wrap algorithms are intended for applications such as (a) protecting keys while in untrusted storage, or (b)… …
22Punchscan — infobox software caption = developer = Richard Carback, David Chaum, Jeremy Clark, Aleks Essex, and Stefan Popoveniuc. released = frequently updated = yes programming language = Java operating system = Cross platform language = English genre =… …
23Quantum computer — A quantum computer is a device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. In a classical (or conventional) computer, information is… …
24Chaffing and winnowing — is a cryptographic technique to achieve confidentiality without using encryption when sending data over an insecure channel. The name is derived from agriculture: after grain has been harvested and threshed, it remains mixed together with… …
25Cryptovirology — is a field that studies how to use cryptography to design powerful malicious software. The field was born with the observation that public key cryptography can be used to break the symmetry between what an antivirus analyst sees regarding a virus …
26Cayley-Purser algorithm — The Cayley Purser algorithm was a public key cryptography algorithm published in early 1999 by 16 year old Irishwoman Sarah Flannery, based on an unpublished work by Michael Purser, founder of Baltimore Technologies, a Dublin data security… …
