Security Considerations Rev. 1.2 February 1999 6.2 Data Privacy The use of cryptography (Stream Cypher), mutual authentication, and password verification prevents monitoring and copying the data channel. Therefore, the area of the transponder that only can be accessed enciphered is called “secret area“. To make use of cryptography you need secret data: keys (HITAG 1 and HITAG 2 transponders) and logdata (HITAG 1 transponders). The transponders and the read/write device are provided with identical transport keys and transport logdata by Philips so that you can start operating them right away. In order to offer our OEM clients high flexibility, the configuration of the transponder memory, password, keys and logdata can be changed. We strictly recommend to rigorously restrict these possibilities for the end customers (e.g. for HITAG 1 transponders by setting the Configuration Page to read only, setting password, keys and logdata to neither read nor write).
