    machine authentication

    Machine authentication is the authorization of an automated human-to-machine or machine-to-machine (M2M) communication through verification of a digital certificate or digital credentials. Unlike user authentication, the process does not involve any action on the part of a human.

  • machine-to-machine (M2M)

    Machine-to-machine, or M2M, is a broad label that can be used to describe any technology that enables networked devices to exchange information and perform actions without the manual assistance of humans.

  • man-in-the-middle attack (MitM)

    A man-in-the-middle (MitM) attack is a type of cyber attack in which the attacker secretly intercepts and relays messages between two parties who believe they are communicating directly with each other.

  • meet-in-the-middle attack

    Meet-in-the-middle is a known plaintext attack that can greatly reduce the number of brute-force permutations required to decrypt text that has been encrypted by more than one key.

  • MEMS (micro-electromechanical systems)

    A MEMS (micro-electromechanical system) is a miniature machine that has both mechanical and electronic components.

  • mesh network topology (mesh network)

    A mesh network is a network in which devices -- or nodes -- are linked together, branching off other devices or nodes.

  • micro-location

    Micro-location is the process of pinpointing a person's placement to within a few inches or feet using various technologies.

  • microcomputer

    A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC, a computer designed for an individual.

  • microcontroller (MCU)

    A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.

  • mobile robot (mobile robotics)

    A mobile robot is a machine controlled by software that use sensors and other technology to identify its surroundings and move around its environment.

  • MQTT (MQ Telemetry Transport)

    MQTT (MQ Telemetry Transport) is a lightweight open messaging protocol that provides resource-constrained network clients with a simple way to distribute telemetry information in low-bandwidth environments.
