摘要
非接触IC卡出现得较晚,但它具有一些接触式IC卡所不能替代的优点,因此它在某些应用领域发展很快,例如高速公路收费系统中的收费介质,城市公交中的电子车票等都采用的是非接触的IC卡,它具有比较强的安全机制,但又不是一种真正意义上的智能卡,本文研究了非接触卡的安全机制,加密算法,并对非接触IC卡的密钥分发进行了改进,从而提高了系统的安全性。
The contactless IC Card emerges in recent years, but for its unique merits, it was widely used in many fields. For example, the electronic toll collection of highway and the electronic ticket of public transportation were all based upon contactless IC card. Though the contactless IC card is not a kind of really CPU card, its security mechanism is strong. In this paper security mechanism of this kind of card was studied. The improvement of key distribution was presented to enhance the security in the toll collection system.
