A data erasing device for use with a key system that allows at least one of an electronic key, a mobile terminal, and an authentication card to be used as a key of an operated subject. The electronic key functions as the key and is verified through wireless communication, the mobile terminal is used as the key by registering a digital key provided from an external device, and the authentication card is verified as the key through proximity wireless communication. A checking unit checks a result of a substitute authentication performed when at least one of the electronic key, the mobile terminal, and the authentication card that is used as the key is lost. The substitute authentication differs from an authentication performed on the lost key. An erasing unit erases key data of the lost key from a memory when the checking unit obtains a checking result indicating successful authentication.

A system can include a plurality of devices including a master device for authenticating processes and one or more requesting devices. The master device can include a master host security service configured to authenticate the one or more processes of the system. The master host security service can run a certificate authority to generate a root certificate and a private root key corresponding to the root certificate. A respective host security service can receive a request for a process manifest for a requesting process of a respective device from a respective orchestration service. The respective host security service can generate the process manifest for the requesting process and provide the process manifest to the requesting process. The requesting process can use the process manifest to communicate with the certificate authority to obtain an operational certificate based on the root certificate.

The disclosed technology teaches providing limited usage of a first device that includes local resources for verifying authenticity of a Macaroon access token with caveats (MATwC), a unique key and a local proximity interface. A second device used by the service technician receives the MATwC, establishes a connection with the first device over the local proximity interface using the MATwC, and sends a request to enter limited usage mode. The MATwC originated with an authentication server as a MAT, using the unique key of the first device and modified by appending caveats that narrowed authorization provided by the MAT with the limited usage mode, and applied a message authentication code chaining algorithm to sign a resulting the MATwC. The first device performs local authentication of the MATwC, evaluating the appended caveats and enters the limited usage mode consistent with the appended caveats, without requiring connected resources to authenticate the MATwC.
