What is Public Key Infrastructure (PKI)? Public Key Infrastructure (PKI) is a set of hardware, software, people, policies, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates. In cryptography, a PKI is an arrangement that binds public keys with respective user identities by means of a certificate authority (CA). Wikipedia.org
Temporal Key Integrity Protocol (TKIP) WPA requires encryption by using TKIP. TKIP replaces WEP with an encryption algorithm that is stronger than the WEP algorithm but uses the calculation technologies present on existing wireless devices to perform encryption operations.
