Definition[edit | edit source]

A hardware security module (also called a host security module) (HSM) is a type of secure cryptoprocessor targeted at managing digital keys, accelerating cryptoprocesses in terms of digital signings/second and for providing strong authentication to access critical keys for server applications. These modules are physical devices that traditionally come in the form of a plug-in card or an external TCP/IP security device that can be attached directly to the server or general purpose computer.
