密钥管理系统、密钥管理方法以及通信装置
摘要：
在密钥管理系统中，RFID标签(70)对作为根据主密钥被加密的第一密钥的加密第一密钥进行解密，并将解密的第一密钥存放在服务密钥存放区域(S302)，由第三者服务器(30)对根据第一密钥被加密的第二密钥进行解密(S304)，并根据主密钥对解密的第二密钥进行加密，将作为根据主密钥被加密的第二密钥的加密第二密钥发送到移动信息终端(40)的应用(S305)，对应用所答复的加密第二密钥进行解密，并将解密的第二密钥存放在服务密钥存放区域(S306)。
摘要（英）：

In this key management system, an RFID tag (70) decrypts an encrypted first key which is a first key which has been encrypted with a master key, stores the decrypted first key in a service key store area (S302), decrypts a second key which has been encrypted with the first key by way of a 3rd party server (30) (S304), encrypts the decrypted second key with the master key, transmits the encrypted second key which is the second key which has been encrypted with the master key to an application of a mobile information terminal (40) (S305), and decrypts the encrypted second key which has been returned from the application in order to store the decrypted second key in the service key store area (S306).
