The Spirtech's Solution to Secure Teleticketing Simultaneous Remote Transactions |
|
|
[11/25/09]
Spirtech recently announced a solution to the central management of the Calypso transactions.
The Calypso HSM PCI-S3 meets the needs of modern public transports. Because they serve an increasing number of passengers, transit operators have to face an increased number of remote transactions (between a vending machine and its remote server, between internet customers and dedicated servers but also due to the transactions allowed by the new technologies such as NFC phones).
These new trends lead to new security challenges. When a traveler wishes to load a new season ticket or a simple transport ticket in a contactless portable object - cards, phones, etc., what actually happens? This authorization to modify the data in the Calypso portable object is protected by a secure application module (SAM) which is normally present in every terminal issuing transport contracts. This SAM contains the cryptographic keys necessary for the vending operations and prevents frauds. A SAM can only manage one operation at a time, whereas a server needs to manage many simultaneous transactions (for example during the beginning and ending of season ticket periods). The central management of numerous remote transactions would suppose as many SAM as there are simultaneous transactions.
Spirtech designed the solution to this problem and proposes the Calypso HSM PCI-S3.
Compatible with the Calypso SAM-S1 from Spirtech, the Calypso HSM PCI-S3 can manage up to 10.000 simultaneous transactions (sales, personalization or key loading for cards and tickets). It is installed in a PCI slot of the server PC processing the remote transactions. This technology eases the physical installation and can manage several independent applications (for example different transport networks). Fran?ois GRIEU, CTO of Spirtech, explained that "the technical stakes required developing a powerful, easy to use and standard system able to store the security cryptographic keys in a central server".
Several international transport operators have already acquired the Calypso HSM PCI-S3 developed by Spirtech. All of them use the Calypso technology and wish to improve their services to their customers. Thanks to the Calypso HSM PCI-S3 their customers can now securely load their season tickets at home.
Spirtech has chosen the Calypso technology to develop its first version of the Calypso HSM PCI-S3. Calypso is the teleticketing standard created by the transport operators and promoted by industrialists. The Calypso HSM PCI-S3 includes the Calypso license and can therefore be used with Press Release any terminal, even if not licensed by Calypso. The integration of a Calypso HSM PCI-S3 in a teleticketing system is therefore very easy.
Frederic LEVY, CEO of Spirtech, said: "Complementing the SAM-S1 and the SAM-S20, the Calypso HSM is an important innovation to secure and manage numerous simultaneous transactions. It simplifies the daily life of the passengers in public transport networks".
About the Calypso HSM PCI-S3.
The software library of the HSM Calypso PCI-S3 offers the following functions:
Opening of a channel (equivalent to reserving a SAM-S1).
Exchanging commands (using the SAM-S1 APDU format).
Closing the channel (freeing the reserved SAM-S1).
Management of independent key groups.
Key management (transfer, deletion, invalidation).
Startup secured with a smartcard.
HSM Calypso PCI-S3 Configuration:
PCI-S3: HSM card in PCI format (or PCI Express), evaluated FIPS 140-2 Level 3, to be installed in a PC compatible.
Lib-S3: Software offering the access functions to the PCI-S3 (available under Linux and Windows).
A PCI-S3 replaces from 100 to 10,000 SAM-S1, according to the configuration chosen.
About Spirtech.
Spirtech is an independent engineering and design company, expert in the fields of smart cards, cryptography and teleticketing. Its experts participated to the creation of significant innovations such as the teleticketing standard Calypso. They also designed the SAM-S1 which is used to secure Calypso transactions all over the world. Spirtech advises transport operators and Calypso-licensed companies when they wish to implement Calypso foster interoperability and multimodality in their teleticketing systems. Spirtech is also the technical assistant of Calypso Networks Association. Visit www.spirtech.com for more information.
