====Computer security and cryptography==== {{main|Computer security|Cryptography}} Computer security is a branch of computer technology with the objective of protecting information from unauthorized access, disruption, or modification while maintaining the accessibility and usability of the system for its intended users. Historical [[cryptography]] is the art of writing and deciphering secret messages. Modern cryptography is the scientific study of problems relating to distributed computations that can be attacked.<ref>{{Cite book|last=Katz|first=Jonathan|url=https://www.worldcat.org/oclc/137325053|title=Introduction to modern cryptography|date=2008|publisher=Chapman & Hall/CRC|others=Yehuda Lindell|isbn=978-1-58488-551-1|location=Boca Raton|oclc=137325053|access-date=November 17, 2021|archive-date=May 6, 2022|archive-url=https://web.archive.org/web/20220506003141/http://www.worldcat.org/oclc/137325053|url-status=live}}</ref> Technologies studied in modern cryptography include symmetric and asymmetric [[encryption]], [[digital signature]]s, [[cryptographic hash function]]s, [[key-agreement protocol]]s, [[blockchain]], [[zero-knowledge proof]]s, and [[garbled circuit]]s.
