    • A system is configured for authenticating a chip card interface device (CCID) during a transaction with the CCID. The system has a communication device configured for communicating with the CCID over a network and a processing device coupled with the communication device. The processing device is configured for receiving a transaction initiation communication from the CCID and instructing the communication device to communicate a request for authentication information including a random number to the CCID. The CCID encrypts the random number with a unique chip key (UCK) previously created with a master chip key (MCK). Then, the CCID communicates the encrypted random number to the system along with a serial number. The system recalculates the UCK using the serial number, encrypts a copy of the random number using the recalculated UCK and compares the encrypted copy with the encrypted random number received from the CCID to authenticate the CCID.
    • 系统被配置为在与CCID的交易期间认证芯片卡接口设备(CCID)。 该系统具有配置用于通过网络与CCID进行通信的通信设备和与通信设备耦合的处理设备。 处理装置被配置为从CCID接收事务发起通信,并且指示通信设备向CCID传送包括随机数的认证信息的请求。 CCID使用先前使用主芯片密钥(MCK)创建的唯一芯片密钥(UCK)对随机数进行加密。 然后,CCID将加密的随机数与序列号一起传送到系统。 系统使用序列号重新计算UCK,使用重新计算的UCK加密随机数的副本,并将加密的副本与从CCID接收的加密随机数进行比较,以验证CCID。
