With the threats of card cloning and the vulnerabilities of Wiegand controller signal cloning growing strong within the security market, CEM has introduced the new S-Pass reader and DCM 350 two-door controller with secure RS485 encrypted communications. “Developed as an end to end secure solution, these new CEM products have designed out these security vulnerabilities with the added benefit of an affordable price,” said Andrew Fulton, Business Development Director for CEM Systems.

The CEM S Pass reader is a contactless smart card reader with powerful 3DES (Triple DES) encryption. Available as a keypad or non-keypad option, the S Pass reader connects to the new DCM 350 intelligent two-door controller, which utilises highly encrypted RS485 communications to the S Pass reader. This effectively eliminates the threat and vulnerabilities of controller signal cloning.

In addition to the benefit of highly secure RS485 communications, the DCM 350 (Door Control Module) features an intelligent database for offline card validation. Operating in offline mode, the DCM 350 can hold up to 200,000 cards. It can be configured to support two S Pass readers on two separate doors with optional exit push buttons, or can be configured to support two S Pass readers on a single door for entry/exit control. It is available in two options – the S DCM 350 supports serial devices or the E DCM 350 supports IP devices.

CEM has also introduced a new contactless 13.56 MHz Desfire smart card to eliminate the threat of card cloning. Each card has different sets of encrypted keys that are securely stored on the card for high levels of security. CEM pre-personalises the card memory for customer convenience and cost efficiency. This offers customers a flexible and quick smart card solution, without the cost of card personalisation and key/filing management. The CEM Desfire smart card can hold up to 28 different security applications such as access control and cashless vending, and 32 files per application.

Combined as one highly secure Desfire controller solution, the CEM E DCM 350 two-door controller and S Pass Desfire reader & smart-card will offer the security market a low cost, yet highly secure option when a panel approach is required. Customers will have multiple layers of security from start to end.
