Typical Customer Profile for Secure Sector Smart Cards • Ideal customers for Smart Cards • Customers Seeking Multi-purse Capabilities • Cashless Environments • Library / Lending • Tool Crib • Cashless Vending • Copying With Usage Tracking / Billing • Environments Requiring More Secure Controls • To Prevent Credential “Sniffing” and • To Prevent Counterfeiting. • Corporate or Educational Campus • Any Environment Desiring Ability To Tie The Existing Identity Infrastructure to Any Other Task or Function
What are Fixed Sector Keys? 1 Non-encoded Smart Card Credentials 2 Credential Encoder BID Data Data-1 Data-2 Data-3 . . Data - n Sector Secret Key* Encoded Smart Card Credentials 3 *Secret Key is up to 128 bits • Step 1: GE provides encoded cards utilizing customer’s Fixed Key. (Note: A fixed key credential encoder is planned for Facility Commander Wnx 7.6 and Picture Perfect 4.1 allowing customer more choice in card providers.) • Step 2: Encoding Cards -- Blank Smart Cards are presented to Credential Encoder. The encoder writes a secret key to the specified sector and writes the badge ID data to the user field for that sector. • Step 3: The output is an encoded credential with both a secret key and the badge data stored on the credential. Other sectors are available for other data—vending, library, etc. These steps are repeated for each subsequent card.
Fixed Sector Key Use Transaction Data sent to Controller 4 3 1 2 • Step 1: Card approaches the reader • Step 2: Conversation between the reader and the card ensues. Reader starts by transmitting the secret key for a particular sector on the card. • Step 3: The card compares the secret key provided by the reader to the secret key on the card. If they match, then and only then, does the card release the user data for that particular sector. • Step 4: The reader reads the user data and transmits the information to the controller, in this case, to be used in the access control decision. This process is repeated every time a card approaches the reader. • Note: In the case of FIXED keys, every card uses the same secret key
What are Diversified Sector Keys? 1 Non-encoded Smart Card Credentials 2 Credential Encoder BID Data Data-1 Data-2 Data-3 . . Data - n Secret Key* Algorithm Encoded Smart Card Credentials 3 *Secret Key is up to 128 bits • Step 1: GE provides encoded cards utilizing GE’s Diversified Key. (Note: A Diversified Key is only available directly from GE. There is no field encoding of Diversified Keys.) • Step 2: Encoding Cards -- Blank Smart Cards are presented to Credential Encoder. The encoder contains an algorithm that • requires two data inputs—1) a secret key and 2) a card serial number. The algorithm outputs a unique number or key for each credential and writes a unique secret key to the specified sector and then writes the badge ID data to the user data field for that sector. • Step 3: The output is an encoded credential with a unique secret key and the user badge data stored on the credential. Other sectors are available for other data—vending, library, etc. These steps are repeated for each subsequent card.
Diversified Sector Key Use Transaction Data sent to Controller 5 4 1 2 3 • Step 1: Card approaches the reader. The reader has both the algorithm and the GE secret key stored in it. Therefore, it can • calculate the result key for each card. Conversation between the reader and the card ensues. Reader starts by transmitting the card serial number for a particular sector on the card. • Step 2: The reader runs the algorithm • Step 3: The reader transmits a unique result key for each card & sector. • Step 4: The card compares the result key provided by the reader to the sector key on the card. If they match, then and only then, does the card release the user data for that particular sector. • Step 5: The reader reads the user data and transmits the information to the controller, in this case, to be used in the access control decision. This process is repeated every time a card approaches the reader. • Note: In the case of DIVERSIFIED keys, a UNIQUE result key is calculated for each card. In the unlikely event that a card is compromised, only that particular card is subject to counterfeiting. All others remain secure.
