The present disclosure provides a method and system for remote control of a smart card. The method comprises that: a smart card management platform receives a request of locking or unlocking a smart card from a subscriber; and the smart card management platform performs interactive processing with a terminal side according to the request via a mobile network platform, so as to enable the terminal side to perform the locking or unlocking of the smart card. The present disclosure enables the payment subscriber to avoid loss when the terminal is robbed, lost, stolen, or is illegally used seriously, and provide a higher flexibility to the payment system.

The present application discloses a method and system for remote control of a smart card. The method includes: a smart card management platform receives a request to destroy the smart card from a subscriber (S101); according to the request, the smart card management platform performs interactive processing with a terminal side via a mobile network platform to make the terminal side destroy the smart card (S103). The present application enables the subscriber to avoid loss when the terminal is robbed, lost, stolen, or is illegally used seriously, and provide a higher flexibility to the payment system.

The present invention provides a terminal supporting eNFC and its processing method, in which a card emulation mode is disabled when a user card does not support SWP, and NFC in non card emulation modes can further be supported. A mobile terminal disabling/enabling the NFC function is implemented by the interaction of the mobile terminal with a NFC emulation front end chip therein. When the terminal determines that the user card does not support the Single Wire Protocol (SWP) interface, it disables the Near Field Communication (NFC) function. If the terminal is required to work in a non card emulation mode, the terminal starts a NFC application in the non card emulation mode, and enables the NFC function when determining that the NFC function is in a disabled state; after the NFC ends, the terminal disables the NFC function when determining that the user card does not support the SWP interface. The terminal and its processing method provided in the present invention can reduce the power consumption of the terminal, extend the stand-by time of the terminal, and effectively save resources.

A method for generating a smart card secret key is provided. The method comprises the following steps: the management platform generates a random number for smart card security domain, and uses the random number to generate the dispersion parameter for smart card security domain; the dispersion parameter and the seed secret key of the management platform are taken as the parameters of the dispersion algorithm which is used to generate the secret key for the smart card security domain. When generating the secret key for the smart card security domain, the method generates a new random number for smart card security domain (issuer security domain or supplementary security domain), and uses the newly generated random number to generate a new dispersion parameter, and finally uses the new dispersion parameter to generate a new secret key for the smart card security domain.

The present invention discloses a key distribution method and system, the method includes: a card issuer management platform informing a supplementary security domain corresponding to an application provider of generating in a smart card a public/private key pair including a public key and a private key, receiving the public key returned from the supplementary security domain, importing a public key for trust point for external authentication into the supplementary security domain, and transmitting the information of the supplementary security domain and the public key to the application provider management platform; the application provider management platform receiving the information of the supplementary security domain and the public key from the card issuer management platform, and selecting the supplementary security domain of the smart card by a service terminal according to the information of the supplementary security domain and the public key; the application provider management platform informing the supplementary security domain of regenerating a public key and a private key, generating a supplementary security domain certificate according to the regenerated public key which is returned from the supplementary security domain, and achieving the supplementary security domain key distribution by transmitting the supplementary security domain certificate to the supplementary security domain. The present invention can improve the security of the supplementary security domain key distribution.

A key distribution method and system are provided, and the method includes that: a card issuer management platform generates an initial key of a secondary security domain corresponding to an application provider, imports the initial key and a trusted root public key used for external authentication to the secondary security domain, and sends the information of the secondary security domain and the initial key to an application provider management platform (202); the application provider management platform receives the information of the secondary security domain and the initial key, and selects the secondary security domain of a smart card by a service terminal according to the information of the secondary security domain and the initial key (204); the application provider management platform generates a public key and a private key of the secondary security domain as well as a certificate of the secondary security domain, and encrypts the public key and the private key as well as the certificate and then sends them to the secondary security domain (206). Through the above process, the security of the key distribution for the secondary security domain can be improved.

A method for downloading an application is disclosed by the present invention which is implemented based on an application downloading system including a smart card, a mobile terminal, an Over The Air (OTA) server and an outside-card entity management platform. The outside-card entity management platform establishes a connection with the smart card through the OTA server and mobile terminal, selects a security domain for application downloading in the smart card after receiving an application downloading request from the smart card, establishes a security channel with the smart card, and downloads the application to the smart card based on the security channel. By using the system and method for downloading an application of the present invention, the application may be downloaded to the smart card over a mobile communication network at a high speed, in real time, conveniently and safely, with user experience being improved.
