    • Systems, methods, and computer program products for supporting multiple contactless applications using different security keys on a wireless smart device are disclosed. According to one aspect, the subject matter described herein includes a method for supporting multiple contactless applications using different security keys on a wireless smart device. The method includes, at a wireless smart device configured to communicate with a wireless smart device reader, the wireless device including a plurality of contactless applications and a contactless application memory for use by the plurality of contactless applications, initializing a portion of the memory such that access to the portion of memory requires the use of a shared secret key known to the plurality of contactless applications. The method includes reserving the portion of memory for use by one of the plurality of contactless applications by using the shared secret key to set access privileges for the portion of memory such that access to the portion of memory requires the use of a application-specific secret key associated with the one application and not known to the other applications.
    • 公开了用于在无线智能设备上使用不同安全密钥来支持多个非接触式应用的系统,方法和计算机程序产品。 根据一个方面,本文描述的主题包括一种在无线智能设备上支持使用不同安全密钥的多个非接触式应用的方法。 该方法包括在被配置为与无线智能设备读取器进行通信的无线智能设备中,该无线设备包括多个非接触式应用和非接触式应用存储器,供多个非接触式应用使用,初始化存储器的一部分,使得 对存储器部分的访问需要使用多个非接触应用已知的共享秘密密钥。 该方法包括通过使用共享秘密密钥来为存储器的该部分设置访问特权来保留存储器的一部分供多个非接触式应用中的一个使用,使得对该部分存储器的访问需要使用特定应用程序的秘密 密钥与一个应用程序相关联,并且不被其他应用程序所知。
