Authentication
Especially for applications with high-security demands such as immobilizer systems, the
e5561 contains an optimized authentication procedure with the following advantages:
Secure and fast authentication (< 100 ms)
Application-optimized high-security algorithm
Customer-specific generation of unique keys
Therefore, a high-security data transmission and encryption as well as a short authenti-
cation time is achieved.
For further information, some additional documentation and programs are available:
