PEAP: Protected Extensible Authentication Protocol
Protected Extensible Authentication Protocol(PEAP), a protocol developed by Microsoft, Cisco and RSA Security as an open standard, is used to authenticate wireless LAN clients without requiring them to have certificates. PEAP is a method to securely transmit authentication information, including passwords, over wireless networks. PEAP utilizes Transport Layer Security (TLS) to set up an end-to-end tunnel to transfer the user's credentials without having to use a certificate on the client. PEAP uses only server-side public key certificates to authenticate clients by creating an encrypted SSL/TLS tunnel between the client and the authentication server, which protects the ensuing exchange of authentication information from casual inspection.
