PUBLIC KEY INFRASTRUCTURE

Domain	Definition
Computing	Public Key Infrastructure (PKI) A system of public key encryption using digital certificates from Certificate Authorities and other registration authorities that verify and authenticate the validity of each party involved in an electronic transaction. PKIs are currently evolving and there is no single PKI nor even a single agreed-upon standard for setting up a PKI. However, nearly everyone agrees that reliable PKIs are necessary before electronic commerce can become widespread. US DOD PKI (http://www-pki.itsi.disa.mil/). US NIST PKI (http://csrc.ncsl.nist.gov/pki/). IETF PKIX Working Group (http://www.imc.org/ietf-pkix/). (1999-11-30). Source: The Free On-line Dictionary of Computing.

Business		The Hungarian "Law on Digital Signature" is expected to be passed by the country's Parliament by June 2001. This law would speed up the spread of Public Key Infrastructure (PKI), and software that is related to digital signature will be one of the best sales prospects besides single sign-on authentication/authorization, content screening and antivirus software products.
