User authentication technologies based on mobile platforms

射频识别(RFID)卡和读卡器广泛用于身份验证用户的多种应用，如建筑物的物理访问、公共交通和信用卡交易。不幸的是，正如之前的研究表明的那样，目前的商业解决方案是不安全的。一个根本的问题是，RFID卡没有使用强加密所需的计算能力。另一个问题是，RFID读取器不能现场升级，这使得它们在部署的整个生命周期中都面临漏洞。

Radio Frequency Identification (RFID) cards and readers are widely to authentication users in multiple applications such as physical access to buildings, public transportation and credit card transactions. Unfortunately, current commercial solutions are insecure as previous research has demonstrated. One fundamental problem is that RFID cards do not have the computing power required to use strong cryptography. Another issue is that RFID readers are not field upgradable, which leaves them exposed to vulnerabilities for the full life cycle of their deployment.
