Abstract: In one example embodiment, an information processing apparatus determines whether a target ID is a unique ID or a partial randomization ID that includes a first part being replaced by a different number and a second part being generated based on the unique ID. In response to the target ID being the partial randomization ID, the information processing apparatus generates an access key based on the second part of the partial randomization ID and a key. The information processing apparatus executes a mutual authentication process using the generated access key.

Abstract: PROBLEM TO BE SOLVED: To accurately obtain waiting time up to command retransmission from a controller. SOLUTION: After card command transmission processing, a reader/writer calculates total waiting time and transmits the calculated total waiting time to a controller 11 as an accepted packet (step S13). Concretely, the reader/writer calculates card waiting time by adding card command transmission processing time to the maximum response waiting time of card response. Further, the reader/writer calculates total waiting time according to following formula: total wait time = card waiting time × (retrial frequency +1)+ card access response generation time. This invention can be applied to a non-contact communication system. COPYRIGHT: (C)2011,JPO&INPIT
Abstract translation: 要解决的问题：准确地获取从控制器发出命令的等待时间。 解决方案：在卡命令发送处理之后，读写器计算总等待时间，并将所计算的总等待时间作为接受的分组发送到控制器11（步骤S13）。 具体地，读写器通过将卡命令发送处理时间添加到卡响应的最大响应等待时间来计算卡等待时间。 此外，读写器根据以下公式计算总等待时间：总等待时间=卡等待时间×（重试频率+1）+卡访问响应生成时间。 本发明可以应用于非接触式通信系统。 版权所有（C）2011，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of a card-unique ID of an IC card. SOLUTION: In step S12, a state of a held target ID randomization flag is determined. When the target ID randomization flag is determined to be valid, a partial randomization ID is notified as a target ID to an R/W 10. In such a case, an access key is generated by making two bytes of a lower-order of a card number of the partial randomization ID act on a degeneration key. To the contrary, when the target ID randomization flag is determined to be invalid, the card-unique ID is notified as a target ID to the R/W. In such a case, the access key is generated by making six bytes of a card number of the card-unique ID act on the degeneration key. The invention is applicable to a contactless communication system.
