A public key infrastructure ( PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
As a framework, [1] ISAKMP typically utilizes IKE for key exchange, although other methods have been implemented such as Kerberized Internet Negotiation of Keys. A Preliminary SA is formed using this protocol; later a fresh keying is done. ISAKMP defines procedures and packet formats to establish, negotiate, modify and delete Security Associations.
With Diffie-Hellman key exchange, two parties arrive at a common secret key, without passing the common secret key across the public channel. Diffie–Hellman (DH) key exchange [nb 1] is a mathematical method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman.
Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity. [ 1] Code signing was invented in 1995 by Michael Doyle, as part of ...
Wi-Fi Protected Access ( WPA ), Wi-Fi Protected Access 2 ( WPA2 ), and Wi-Fi Protected Access 3 ( WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired ...
