| Design Experience of WIM Card for M-Commerce |
Abstract
We present our design experience of WAP Identity Module(WIM), which will be
a very versatile device for secure M-commerce. WIM cooperates with wireless
transport layer security(WTLS) to authenticate participating parties and to
provide confidentiality of network traffic. To achieve the purpose, various
standards including wireless public key infrastructure(WPKI), X.509, ISO 7816
and PKCS#15 are supported in the WIM card.
ETRI WIM implementation is designed in strict layering approach, which separates the transport layer protocol and the application protocol from the
overall structure. This layered approach helps developers upgrade easily the internal
software modules.
Besides the WIM card, we show how the mobile terminal interacts with the WIM card in the device driver level.
Though smard cards with publickey cryptography does not yet have many applications
in Korea, use of them is growing gradually with the increase of M-commerce.
