TKEY
TKEY (transaction key) is a record type of the Domain Name System. TKEY RRs can be used in a number of different modes to establish shared keys between a DNS resolver and server. TKEY record format Mode field values * 0 - Reserved * 1 - Server assignment * 2 - Diffie-Hellman exchange * 3 - Generic Security Service Algorithm for Secret Key Transaction * 4 - Resolver assignment * 5 - key deletion * 6–65534 - available * 65535 - reserved; See also * Domain Name System * List of DNS record types This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System The Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resour ...

List Of DNS Record Types
This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System The Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names assigned to ... (DNS). It also contains pseudo-RRs. Resource records Other types and pseudo-RRs Other types of records simply provide some types of information (for example, an HINFO record gives a description of the type of computer/OS a host uses), or others return data used in experimental features. The "type" field is also used in the protocol for various operations. Obsolete record types Progress has rendered some of the originally defined record-types obsolete. Of the records listed at IANA, some have limited use, for various reasons. Some are marked obsolete in the list, some are for very obscure services, some are ...

Generic Security Service Algorithm For Secret Key Transaction
GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is an extension to the TSIG DNS authentication protocol for secure key exchange. It is a GSS-API algorithm which uses Kerberos for passing security tokens to provide authentication, integrity and confidentiality. GSS-TSIG (RFC 3645) uses a mechanism like SPNEGO with Kerberos or NTLM. In Windows, this implementation is called ''Secure Dynamic Update''. GSS-TSIG uses TKEY records for key exchange between the DNS client and server in GSS-TSIG mode. For authentication between the DNS client and Active Directory Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was used only for centralize ..., the AS-REQ, AS-REP, TGS-REQ, TGS-REP exchanges must take place for granting of ticket and establishing a security context. The security context has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domain Name System
The Domain Name System (DNS) is a hierarchical and distributed naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over sub-domains of their allocated name space to other name servers. This mechanism provides distributed and fault tolerance, fault-tolerant service and was designed to avoid a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Name Server
A name server refers to the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet. The most important function of DNS servers is the translation (resolution) of human-memorable domain names (example.com) and hostnames into the corresponding numeric Internet Protocol (IP) addresses (192.0.2.1), the second principal name space of the Internet, which is used to identify and locate computer systems and resources on the Internet. Although it is typically used in reference to DNS (Domain Name System), the term name server may also be used for any computer application that implements a network service for providing responses to queries against a directory service which translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request. Domain Name Server The Internet maintains two princi ...

Octet (computing)
The octet is a unit of digital information in computing and telecommunications that consists of eight bits. The term is often used when the term byte might be ambiguous, as the byte has historically been used for storage units of a variety of sizes. The term ''octad(e)'' for eight bits is no longer common. Definition The international standard IEC 60027-2, chapter 3.8.2, states that a byte is an octet of bits. However, the unit byte has historically been platform-dependent and has represented various storage sizes in the history of computing. Due to the influence of several major computer architectures and product lines, the byte became overwhelmingly associated with eight bits. This meaning of ''byte'' is codified in such standards as ISO/IEC 80000-13. While ''byte'' and ''octet'' are often used synonymously, those working with certain legacy systems are careful to avoid ambiguity. Octets can be represented using number systems of varying bases such as the hexadeci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
