Glossary
route map Route maps enable you to control information that is added to the routing table.
SDM automatically creates route maps to prevent NAT from translating specific
source addresses when doing so would prevent packets from matching criteria in
an IPSec rule.
RPC remote procedure call. RPCs are procedure calls that are built or specified by
clients and executed on servers, with the results returned over the network to the
clients. See also client/server computing.
RSA Rivest, Shamir, and Adelman, the inventors of this cryptographic key exchange
technique, which is based on factoring large numbers. RSA is also the name of
the technique itself. RSA may be used for encryption and authentication, and is
included in many security protocols.
RSA keys An RSA asymmetric key pair is a set of matching public and private keys.
RSA signatures One of three authentication methods offered in IPSec, with the other two
methods being RSA encrypted nonces, and pre-shared keys. Also, o ne of the
three Federal Information Processing Standards (FIPS)–approved algorithms for
generating and verifying digital signatures. The other approved algorithms are
DSA and Elliptic Curve DSA.
SDM Cisco Router and Security Device Manager. Cisco SDM is an Internet
browser-based software tool designed to configure LAN, WAN, and security
features on a router. See Getting Started for more information.
rule Information added to the configuration to define your security policy in the form
of conditional statements that instruct the router how to react to a particular
situation.
