MANAGING THE SECURITY Chips and readers- USER’S GUIDE INSIDE security protects memory from READING and/or WRITING. Security control e-purse (stored value) management Security is based on : - key diversification - authentication -signature Key diversification implies that each security calculation is different for each card INSIDE chips security is based on secret keys that protect and authentify the chip content. On one hand, keys are stored in the chip.
Chips and readers- USER’S GUIDE Authentication protects the memory from reading and writing Signature when writing increases memory content security Authentication Authentication algorithm performs a mutual authentication. The principle is as follows : Data are exchanged then both device perform secret calculations on them to obtain 2 results on 4 bytes. Authentication is done if they get the same results. The chip first checks coupler’s response then reader verifies chip’s results. 1.
Chips and readers- USER’S GUIDE First step in security is to load the secret keys into the coupler Version 1.0 KEY LOADING To perform this complex operation, use the function supplied with the libraries (C Libraries, ActiveX component). You will find encryption algorithm in annex. C source code is provided in the C libary, and ActiveX component manage automatically all security calculation. You need to give the following parameter : " Key number " Exchange Key " New Key value ! ActiveX method : Mx.
