Tokens help protect against information theft, viruses and malware

02 December 2010

Nexus GB has launched Datakey Electronics’ new high capacity line (HCL) of portable memory tokens in the UK and Ireland. The HCL tokens differ from SD cards and USB flash drives in three important ways. The first is that the memory token's unique form-factor means that it can't plug into an un-adapted PC or system, which helps to protect the data on the token.

The unique form-factor of the receptacle can also prevent consumer devices from plugging into the OEM’s system, which helps protect that system from unauthorized access, and prevents malicious files, such as viruses and Trojans, from being uploaded.
 

The token's controlled availability virtually assures that only approved devices are used in the OEM system and provides the OEM with an additional revenue stream from the sale of memory tokens to their users. Furthermore, this means that should a data token be lost or stolen the data stored on it can’t be accessed by anyone without an appropriately adapted PC or system.

Secondly the tokens are manufactured using a solid over-moulding process and are constructed out of an ultra rugged composite plastic material.  This makes them impervious to penetration by liquids and practically crush-proof.

The final major difference is that the HCL range uses a contact system with a high lifespan of 50,000 cycles, compared to just 1,500 cycles for most type A USB receptacles.  At just ten cycles per day a USB Type A receptacle will exceed its rated lifespan in only five months.  At the same ten cycle per day rate, it would take a Datakey Electronics receptacle 13 years to exceed its rated lifespan.

These advantages mean that new HCL range combines the large memory and high throughput of consumer products, like USB flash drives and SD cards, with the advantages of an industrial memory token. Other benefits include reliable operation and the harsh environment capability of Datakey Electronics tokens and receptacles. The HCL range comes with 4GB of non-volatile memory as standard, with larger capacities of up to 32GB available.
 
The High Capacity Line includes two families of memory tokens; the DFX series, which delivers a high-performance SD (secure digital) interface, including SPI (Serial Peripheral Interface), and the UFX series, which delivers a USB 2.0 high speed connection. As a result, these new memory tokens are easily integrated into embedded controllers, single board computers and industrial PC designs, as many of these devices are fitted with one or more of these serial interfaces. Integration is straightforward and is typically accomplished by adding one of Datakey Electronics' industrial mating receptacles.

Datakey Electronics’ range of receptacles features multiple mounting options including through-hole, surface mount, and panel mount versions.  Panel mount options are available in IP65, IP67 and EMI-reduction versions to meet the needs of harsh environment applications.  All of the receptacles are rated for 50,000 cycles and withstand shock and vibration, extreme temperatures, humidity, salt-fog environments and exposure to various chemicals.
