Abstract:
The present application discloses a data interaction method and a data interaction device for a composite smart card device, in which, the composite smart card device includes a smart card and a U-shield in a communication connection with the smart card. The data interaction method includes: establishing a communication connection between the smart card and the terminal via the U-shield; and establishing a data security channel between the composite smart card device and a background server via the terminal to enable data interaction between the composite smart card device and the background server through the data security channel, in which, the data transmitted by the data security channel are all encrypted. Technical solutions provided by the present application can effectively improve the security of the data interaction in smart card applications.

Claim (Index 8):
The device of  claim 7 , wherein the data-security-channel establishing unit comprises:\n a negotiation unit configured to negotiate a symmetric key with the background server via the terminal; and a determination unit configured to determine the symmetric key as an encrypted key applicable to the data security channel.
