Security is a key requirement for many contactless applications. Being a permanent process rather than an attribute, security is pointless without its context. Therefore, LEGIC pursues a holistic security philosophy which respects each customer's situation and challenges.

LEGIC is the innovative pioneer in 13.56 MHz contactless smart card technology. Our market-driven and future oriented solutions are used in thousands of installations covering all kinds of applications. Its unique features, structural flexibility and scalability as well as its unmatched backward compatibility ensure our customers optimal protection of their investment. LEGIC’s competitive edge is based on using the latest technology, and combining solid cryptography with simplicity and sophisticated control functions. We are dedicated to serve the needs of our customers by providing tried-and-tested technologies for all the different applications around contactless smart cards.

Our security philosophy is built on three keystones: evolution, isolation, and combination.

Evolution
We continuously improve our security technologies and drive this evolution with a thorough research and development program. This ensures the availability of advanced state-of-the art technology for your application. Existing systems can in fact equally benefit from latest developments by upgrading to the latest software versions, often also in the field.

Isolation
Applications and associated data are always clearly linked to each other. This identification is managed by LEGIC’s unique Master-Tokens. In case a certain product generation can no longer provide the required level of trust, the related application data can be identified and isolated and updated or even erased.

Combination
Security can be increased by combining different security elements. The combination with other security means (e.g. card plus PIN, fingerprint, background system checks, CCTV, etc.) or the introduction of unique user keys as additional security elements provide an increased overall protection of facilities and assets.

As security is a dynamic process we recommend to always apply the latest generation of security technologies. The white papers and links on the right side of this web page provide further information. Licensed LEGIC partners have access to detailed information and documents via their Partner-Login.

End customers of contactless applications consult preferably with their system suppliers – or use the LEGIC Partner Network – to benefit from applications based on the very latest LEGIC technology generation.

LEGIC advant offers advanced security for data and applications, from host communication to data memory on the transponder. The encryption level, based on the industrial standard algorithm AES 128/256 bit / DES / 3DES, can be individually configured for applications and data path sections. This provides the best degree of protection in an open standardised world. Several LEGIC products provide the possibility to upgrade the security software in the field, which is unique in the industry.

The LEGIC advant technology platform offers a ready-to-use encryption package on a high level. Security features of the LEGIC technology platform include:

• Mutual authentication, data encryption and message authentication (MAC)
• Choice of Industrial standard algorithms AES, 3DES, DES, 
• LEGIC offers CC EAL4+, CC EAL 5+ certified hardware platforms 
• Unique serial numbers for transponders and reader modules
• User definable read and write encryption keys
• Automatic key diversification
• Selectable cryptographic data transmission and storage along complete data path from host to transponder (end-to-end security)
