DEVELOPMENT OF THE AUTHORIZATION SYSTEM STRUCTURE FOR USERS OF AUTOMATED WORKING STATIONS OF DISPATCH CENTRALIZATION

The article addresses the problem of password management for shared accounts of the Moscow Metro Dispatch Centralization software (DC-MM). The current practice is described, in which several train dispatchers share a single account on a shift basis, and a new password is generated monthly by a programmer and delivered to the senior train dispatcher in a paper envelope in person. The risks of this approach are identified: delays in receiving the password under shift schedules, possible loss of the envelope, dependence on manual programmer involvement, and the absence of a guaranteed notification mechanism for all staff sharing the account when a password is changed. The impossibility of modifying the existing DC-MM software and the closed nature of the server component storing credentials in a proprietary binary format are substantiated. A web portal architecture is proposed that enables the senior train dispatcher to independently initiate a shared account password change, with automatic notification of all relevant staff through their personal portal accounts. Interaction with the DC-MM server component is delegated to a dedicated adapter whose implementation is independent of the internal structure of the existing software.
