Abstract:
A method for locking out a remote terminal unit includes: receiving a lockout request, wherein the lockout request includes at least a public key associated with a user, a user identifier, and a terminal identifier; identifying a user profile associated with the user based on the user identifier included in the received lockout request; verifying the public key included in the received lockout request and permission for the user to lockout a remote terminal unit associated with the terminal identifier included in the received lockout request based on data included in the identified user profile; generating a lockout permit, wherein the lockout permit includes at least the public key included in the received lockout request; and transmitting at least a lockout request and the generated lockout permit, wherein the lockout request includes an instruction to place a lockout on the remote terminal unit.
