Glossary for network functionsItem DescriptionsAccess pointThese are stations for relaying electromagnetic signals between computers in a wirelessLAN. When a computer is connected to an access point, it can communicate through thenetwork connected to the access point.AESNext generation standard cryptography standardized by the National Institute of Standardsand Technology (NIST).AES: Advanced Encryption StandardDEFAULT GATEWAYThe devices that are used for different network standards from yours. Default Gatewayenables a connection with other network, by adjusting bilateral differences such ascommunication protocols. If no gateway is specified for the IP address of accessdestination, data will be sent to the host set as the default gateway.DHCPAbbreviation for Dynamic Host Configuration Protocol. This function automatically assignsIP addresses to the connected equipment. If a device with the DHCP server function ispresent within a LAN, it automatically assigns IP addresses to the connected equipment.EAPAbbreviation of PPP Extensible Authentication Protocol. An authentication protocolextended from PPP, which is used for user authentication for remote access. MD5, TLS, S/Key, etc. are supported as authentication methods. This protocol is adopted by the wirelessLAN authentication standard IEEE802.1X, and available methods include EAP-TLS/EAP-TTLS/EAP-LEAP/EAP-PEAP/EAP-MD5.EAP-FASTAbbreviation of EAP-Flexible Authentication via Secure Tunneling. It is one of thewireless authentication methods compatible with IEEE802.1X. It does not require digitalauthentication, but establishes a tunnel for the authentication process using a secret keycryptosystem, and authenticates the tunnel mutually to improve security. Cisco’s proprietarymethod.EAP-TTLSAbbreviation of EAP-Tunneled Transport Layer Security. It is one of the wirelessauthentication methods compatible with IEEE802.1X. It performs mutual authentication witha digital certificate by the authentication server, and ID/password by the client. A tunnel isestablished for the authentication process. Developed by Func Software in the U.S.GTC(EAP-GTC)Abbreviation of EAP-Generic Token Card. It is one of the wireless authentication methodscompatible with IEEE802.1X. Authentication is performed with ID and password. Passwordis acquired from a security token.IP ADDRESSInternet Protocol (IP) is a protocol for distributing data, and the address corresponding tothe data distribution destination is called the IP address. The same IP address cannot beused within the same LAN.LAN Abbreviation for Local Area Network. This is a network with a relatively narrow range suchas inside a company.MAC AddressEach network adapter has its own ID No.A discrete ID No. is assigned to each and every network adapter around the world. TheseIDs are used to exchange data between adapters. These IDs are a combination of adiscrete number managed and assigned by the IEEE to each individual manufacturer and aunique number assigned to each individual adapter by the manufacturer.MD5 (EAP-MD5)Abbreviation of EAP-Message digest algorithm 5. It is one of the wireless authenticationmethods compatible with IEEE802.1X. Authentication is performed with ID and password.Password is sent encrypted with challenge & response method.Miracast Developed by the Wi-Fi Alliance, a standard for transmitting the screen of the devicewirelessly.MS-CHAPv2(EAP-MS-CHAPv2)Abbreviation of EAP-Microsoft Challenge Handshake Authentication Protocol v2. It is oneof the wireless authentication methods compatible with IEEE802.1X.It performs mutualauthentication using a one-way encrypted password.Open System / OPEN This is an authentication of wireless signals employing a public key encryptosystem.PEAPAbbreviation for EAP-Protected EAP. It is one of the wireless authentication methodscompatible with IEEE802.1X. It performs mutual authentication with a digital certificate bythe authentication server, and ID/password by the client.ENGLISH - 143Chapter 7 Appendix - Glossary for network functions
