    • The security of an IC card is improved by managing success and failure in authentication individually for each terminal program. An IC card includes a random number generation section, a source authentication section, and a process execution section. Upon receipt of a message of type “1”, the random number generation section generates a random number n, and stores it in a random number storage section by associating the random number n with a source included in the message. Upon receipt of a message of type “2” from the source and in a case where the random number n corresponding to the source is stored, the source authentication section collates a value m calculated from an authentication key held by the IC card and the random number n with a value m included in the message of type “2”. When both values agree, upon receipt of a message of type “3” from the source, the process execution section executes a process in accordance with a type of the message.
    • 通过管理每个终端程序的认证成功和失败来提高IC卡的安全性。 IC卡包括随机数生成部,源认证部和处理执行部。 在接收到类型“1”的消息时,随机数生成部分生成随机数n,并通过将随机数n与消息中包含的源相关联将其存储在随机数存储部中。 在从源接收到类型“2”的消息时,并且在存储与源相对应的随机数n的情况下,源认证部分将从由IC卡保存的认证密钥计算出的值m和随机数 数字n具有包含在类型“2”的消息中的值m。 当两个值同意时,在从源接收到类型“3”的消息时,处理执行部分根据消息的类型执行处理。
