Beside the standard authentication service on GUARDIAN systems (which is based on static passwords), the authentication service $AS offers an additional method:

• Challenge/Response and
• TimeToken

Authentication, based on Atalla and Vasco Challenge/Response Devices.
It is intended to be used by customer applications, such as PATHWAY applications, as well as GHS products.

Features:

• The $AS system is monitored by a PATHMON process pair, due to availability reasons.
  ANY running PATHMON can be used.
• It runs as a server class: The PATHMON in charge of $AS is responsible for starting/re-starting the service.
• The $AS process can be reached through PATHSEND, or directly with OPEN/WRITEREAD/CLOSE procedures.
• $AS process supports the following messages:
  - Generate a random number
  - Check a Challenge/Response number pair
  - Check a TimeToken
  - Authentication Request (initialization)
  - Authentication (finalization)
  - Return statistical information

• INITACR, a block mode program to initialize Atalla (or compatible) Challenge/Response Token.
• ASCOM, (Authentication Server Command Interpreter) allowing the management of the $AS system.

Additional $AS features

• After three consecutive failed checks, the requesting process is delayed for a configurable time. This prevents an exhaustive search for a valid Challenge/Response Number Pair.
• $AS is developed and compiled on an S-Series system, running G06.

This design allows the $AS to become the central authentication service on a Tandem system, even on a network of Tandem systems!
