I have google and read Nolan's:
"Information Hiding Methods used by FlexLM Targets"
"Key Extraction and Encryption Algorithm Reversing"
"Making Tools Work Together"
"Reversing the report encryption algorithm for the flexlm license manager'
"describes an attack on the keys for FlexLM itself"

BUt I haven't found any information for it .

Can you tell me is there any other article about it?
Thanks !
