Security and Protection Introduction
Security and Protection
General
The transaction activities of the TopKAT PLUS are secured and protected for transmission and
authorization activities.
Authorization Security
The contactless tags include Triple-Data Encryption Standard (TDES) encrypted data for user
identification and billing. Consequently, TopKAT PLUS includes a special Security
Application Module (SAM) for decryption and matching identification. On tag reading,
TopKAT PLUS attempts to decrypt the string from the tag. TopKAT PLUS disregards tags
whose security scheme does not match the TopKAT PLUS internal SAM.
Network Security
The Ethernet LAN is isolated from the external Wide Area Network (WAN) by the site
controller (OrCU). In case of remote maintenance, a firewall must be applied either at the
router level or preferably at the home base station level.
Maintenance Security
TopKAT PLUS maintenance and setup procedures require inserting a user name and password
for access. For more information, refer to MDE-4817 SiteOmat In-House Station Controller
Setup and Maintenance Manual.

sealed to prevent humidity and dust penetration.
