摘要
针对当前Android移动终端数据加密保护方案中存在的密钥安全存储及使用问题,提出了一种基于RFID智能卡的机卡分离数据保护方案。方案使用具有密码计算功能的RFID智能卡作为密钥保护的重要组件,移动终端通过Android系统具备的NFC功能,实现对RFID智能卡的密码操作,和RFID智能卡共同配合实现对移动终端数据的双重加密保护。该方案对移动终端无特殊硬件要求,具有更好的易用性。对系统方案进行了分析、实现以及性能测试,分析及测试结果表明该方案具有较好的安全性与可行性。
In view of the problem of insecure key protection and usage that currently exists in the data protection scheme for Android mobile terminal, this paper proposes a RFID smartcard-based data protection scheme, which introduces the RFID smartcard as an important factor to secure the key. The NFC function enables the terminal to do cryptographic operations on RFID smartcard and cooperate with the RFID smartcard to realize double encryption protection. The scheme has no special hardware requirements for the mobile terminal and acquires better ease of use. The scheme has been analyzed,realized and tested. The analysis and experimental results show the scheme is possessed with better security and feasibility.
