Glossary Router: A router is a network device that examines the IP address within a data packet and forwards the packet on towards its destination. The sharing of information between routers about paths to other network destinations is achieved using protocols such as Router Information Protocol (RIP), Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). RSA public key algorithm: The RSA algorithm is named after cryptographers Rivest, Shamir and Adleman, and is used in public key cryptography to establish a public plus private key pair. The algorithm starts with two large primes, p and q, whose product n = pq. A number e is chosen that is less than n and such that e and (p-1)(q-1) have no common factor except 1. Another number d is found such that (ed - 1) is divisible by (p-1)(q-1). The public key is the pair (n, e), the private key is (n, d). The security of the RSA algorithm is based on the difficulty of factoring a product of two large prime numbers. If this could be done then the private key could be computed from the public key. Scatternet: A scatternet is the linking of multiple co-located Bluetooth piconets through the sharing of a common device. A device in a scatternet can be both a master in one piconet and a slave in another. Service Set Identifier (SSID): The SSID identifies a group of wireless devices networked through a single access point. Data packets transmitted between these devices are identified by carrying the SSID, and will be ignored by devices operating under a different SSID. Simple Network Management Protocol (SNMP): Simple Network Management Protocol is a communications protocol that enables the con- figuration and monitoring of network devices such as access points and gateways. SNMP is used to perform network management
