See Encryption for more details. The reader works in the exactly same way like the Authentec family readers. Both kHz and 13,6MHz versions are available. It also detects if the token has been put away and it allows to check if the token is still present in the vicinity of the reader. KeyShield offers unique protection mechanism to avoid this risk — token ID is encrypted hashed on the KeyShield client side once it is read by the reader. Work factor and salt parameters influence how the hashed number is generated.

The driver must be installed in order to avoid this — the reader is listed as a generic USB device after the successful installation of the driver. This is the default format for all drivers.

Windows basic reader class — it sends token ID only once when the token is detected. Windows basic class — it sends token ID only once when the token is detected.

Because of the algorithm used, b-crypt, it is not then possible to find the original chip ID. Authentec family of readers is originally designed as a HW emulator ggiatek keyboard.

For some classes of cards such as MIFARE it’s possible to use a single command to read card unique ID, but for most contact cards commands are different for each manufacturer. Windows Driver for contact and contactless This cpr300m improves security — once Authentec library is chosen for example, no other device can be used to provide the token ID.

HWToken Library documentation Client configuration is platform independent but HWToken libraries are platform specific — see Platforms list for each library.

Estellar setting generates token ID strings identical to the IDs of the attendance system which allows to share issued tokens list by both systems. Default work factor was carefully chosen as a compromise between good security and hashing speed. The default is fast enough to not be noticed and will still be strong enough. If it’s not specified, default salt will ppcr300m used. SK, OmniKey reader.

Contactless smart cards will work with any contactless reader as the communication protocol is standardized.

Work factor and salt parameters influence how the hashed number is generated. Attention — because of this, you must configure salt and work factor parameters only once and not change them later. It is an abstraction layer to allow to work with all the different readers and tokens in a unified way.

Please contact your reseller for more information about supported readers. Using a high work factor makes it incredibly difficult to execute a brute-force attack, but can put unnecessary load on the system. It is sending commands and receiving responses from reader or driver. Each gigtek supports 3 token ID format modes.

If an invalid number is used, the encryption does not work and then only zeroes are return as the card ID. This can expose token IDs to all the directory administrators and then it is theoretically possible to issue duplicate token. Pcr3300m factor value determines how slow the hash function will be, means different work factor will generate different hash values in a different time span.

You can use for example online service at https: If it’s not specified, lcr300m work factor 12 will be used. Different work factor and salt parameters will generate different hashed token ID with the same input token ID same card or token.

For contactless smart cards this setting is not used as the command for reading card ID is standardized.

KeyShield allows to assign virtually unlimited number of prc300m resp. See Encryption for more details. It is not possible to detect if the token has been put away nor to check if the token is still present in the vicinity of the reader.

Single sign on solution for. It also detects if the token has been put away and it allows to check if the token is still present in the vicinity of the reader. Token presence in the vicinity of the gigayek and token being put away are not detected.
