DKIM allows the receiver to check that an email that claimed to have come from a specific domain was indeed authorized by the owner of that domain. [1]
A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. [1][2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity-related ...

Natural key. A natural key (also known as business key[1] or domain key[2]) is a type of unique key in a database formed of attributes that exist and are used in the external world outside the database (i.e. in the business domain or domain of discourse). [3] In the relational model of data, a natural key is a superkey and is therefore a ...
The Domain Name System Security Extensions (DNSSEC) is a suite of extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System (DNS) in Internet Protocol (IP) networks. The protocol provides cryptographic authentication of data, authenticated denial of existence, and data integrity ...
Public key infrastructure. A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
A relational database (RDB[1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [2] A database management system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using SQL (Structured Query Language ...
