New CEM sPass reader, DCM 350 encrypted two-door controller & pre-personalised DESFire smart card now available.

Belfast,February 2011— CEM Systems, part of Tyco Security Products, has announced the release of a new highly secure, yet cost-effective DESFire two-door controller solution.

“With the threats of card cloning and the vulnerabilities of Wiegand controller signal cloning growing strong within the security market, CEM is delighted to announce the release of the new sPass reader and DCM 350 two-door controller with secure RS485 encrypted communications”, said Andrew Fulton, Business Development Director for CEM Systems. “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”.

CEM sPass reader is a contactless smart card reader with powerful 3DES (Triple DES) encryption.  Available as a keypad or non-keypad option, the sPass reader connects to the new DCM 350 intelligent two-door controller, which utilises highly encrypted RS485 communications to the sPass 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 sPass readers on two separate doors with optional Exit push buttons, or can be configured to support two sPass readers on a single door for Entry/Exit control.  It is available in two options – the sDCM 350 supports serial devices or the eDCM 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 eDCM 350 two-door controller and sPass 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:

•             CEM DESFire card level – The CEM per-personalised smart card utilises DESFire encryption to securely store information.  Each card has a unique set of keys that have been encrypted for high security

•             Smart card key management – As keys are managed securely by the system, there are no programming cards. This both increases system security and reduces management overheads.

•             sPass reader level – With a built-in tamper switch, the sPass reader is a highly secure reader as no keys permanently reside in the reader.  sPass reader is available as keypad option for addition PIN security

•             eDCM 350 two-door controller level – The eDCM 350 two-door controller features RS485 encrypted serial communications between the sPass reader and the controller.
