Authentication Unit
The secret algorithm offers a challenge & response procedure for individual card authentication
based both on the Basic and the Extended Authentication Mode of Eurochip 2; the optional use
of Cipher Block Chaining (Extended Authentication Mode only) allows the certification of a
counter decreasing procedure.
Security Interface
Ensures a minimum and a maximum frequency and proper logical voltage levels controlled by
sensors.
Identification and Counter are fully functional compatible with existing members of Eurochip
Family and SLE 4406SP/06SPE products for easy upgrade to higher security levels.
Authentication fully compatible with Basic Authentication mode of Eurochip 1 (SLE 4436/36E)
using Authentication Key 1 and optional Authentication Key 2.
Authentication fully compatible with Basic and Extended Authentication mode of Eurochip 2
(SLE 5536/36E) using Authentication Key 1 and optional Authentication Key 2.
and optional Cipher Block Chaining (Extended Authentication Mode only) of Eurochip 2
(SLE 5536/36E).
SLE 6636com/36Ecom supports Basic and Extended Authentication.
