    • Between an IC card (1) and a electronic ticket server (2), upon purchasing an electronic ticket a public key cryptosystem is employed for a mutual authentication to keep a strict security, and a shared secret between the electronic ticket and a ticket collecting machine is sent on a secure channel as well as the electronic ticket. Upon usage of the electronic ticket, the IC card (1) and the ticket collecting machine (6) mutually judge whether they carry out the mutual authentication by using a public key cryptosystem or a symmetric key cryptosystem. When they determine to use the symmetric key cryptosystem, they carry out the mutual authentication by using the shared secret exchanged beforehand. When they determine to use the public key cryptosystem, they carry out the mutual authentication by using the same method as that used upon purchasing the electronic ticket. This method of mutual authentication can dynamically switch cryptosystems for cryptographic communication between the IC cards or between the IC card and a tamper resistant device having an equivalent function to an IC card installed in related servers or the ticket collecting machine, based on their judgment of the types of bearers, the required degree of security and the required processing speed.
    • 在IC卡(1)和电子票务服务器(2)之间,购买电子票时,使用公共密钥密码系统进行相互认证,以保证严格的安全性,并且在电子票和收票机之间共享秘密 发送在安全的频道以及电子票。 在使用电子票时,IC卡(1)和票收集机(6)相互判断是否通过使用公钥密码系统或对称密钥密码系统进行相互认证。 当他们确定使用对称密钥密码系统时,它们通过使用事先交换的共享密钥来执行相互认证。 当他们确定使用公共密钥密码系统时,它们使用与购买电子机票时相同的方法进行相互认证。 这种相互认证方法可以动态地切换用于IC卡之间或IC卡与具有与安装在相关服务器或收票机中的IC卡具有相同功能的防篡改设备之间的加密通信的密码系统, 承载类型,所需的安全程度和所需的处理速度。

    • An autonomous integrated circuit card includes a logic external communication interface which directly communicates with a communication device connected to an integrated circuit card terminal main body via a network, in addition to a host device interface connected to an integrated card reader/writer via a physical layer. A communication control unit includes a software module which directly communicates with the communication device via the external communication interface. A central processing unit performs authentication via the communication control unit and reads value information stored in a nonvolatile memory. Further, the central processing unit encrypts the read value information by use of an encryption processing unit and directly transmits the encrypted value information to the communication device via the communication control unit and the external communication interface.
    • 自主的集成电路卡除了通过物理层连接到集成读卡器/写入器的主机设备接口之外还包括一个逻辑外部通信接口,该逻辑外部通信接口通过网络直接与连接到集成电路卡终端主体的通信设备通信 。 通信控制单元包括经由外部通信接口与通信设备直接通信的软件模块。 中央处理单元经由通信控制单元执行认证,并读取存储在非易失性存储器中的值信息。 此外,中央处理单元通过使用加密处理单元对读取值信息进行加密,并且经由通信控制单元和外部通信接口将经加密的值信息直接发送到通信设备。
