.
public key
The publicly available component of an integrated asymmetric key pair, often
referred to as the encryption key.
public key cryptography
Cryptography in which a public and private key pair is used, and no security is
needed in the channel itself.
Public Key Crypto Standards
A set of standards for public key cryptography developed in cooperation with an
informal consortium (Apple, DEC, Lotus, Microsoft, MIT, RSA, and Sun) that
includes algorithm-specific and algorithm-independent implementation
standards.
Public Key Infrastructure

RADIUS (Remote Authentication Dial-In User Service)
A protocol for distributed security that secures remote access to networks and
network services against unauthorized access. RADIUS consists of two pieces—
authentication server code and client protocols.
random number
A necessary element in generating unique keys that are unpredictable to an
adversary. True random numbers are typically derived from analog sources, and
usually involve the use of special hardware.
RC4 (Rivest Cipher 4)
A variable key size stream cipher, once a proprietary algorithm of RSA Data
Security, Inc.
RC5 (Rivest Cipher 5)
A block cipher with a variety of arguments, block size, key size, and number of
rounds.
related hosts
A method to place hosts on the optional or external interface when using a
simple or drop-in network configuration. Examples include placing a router on
the external interface or an HTTP server on the optional interface.
