摘　　要：针对目前移动智能终端数据存储易泄露问题,提出一种移动端数据存储安全模型。考虑到移动终端计算能力局限性,提出一种改进的超轻量级加密算法,既能保证数据安全又可提高计算效率。将改进的基于时间戳的认证方案与透明加/解密技术相结合,使文件以密文形式上传到服务器,重新回到移动智能终端时才被解密成明文,实现对用户文件的全生命周期保护,保证数据传输安全性。以iOS客户端为例对方案进行了功能测试,实验表明,该系统能有效保障移动智能终端用户的数据安全性。Aiming at the problem of easy leakage of mobile intelligent terminal data storage,a security model of mobile data storage is proposed.Considering the limitation of computing capability of mobile terminal,we propose an improved ultra-lightweight encryption algorithm in the model both to ensure data security and improve computing efficiency.Since time the model involves the server,so we make use of improved timestamp-based authentication scheme and transparent encryption/decryption technology,so that when the file is uploaded in cipher text to the file server,only to be decrypted into a plaintext after returned to the mobile intelligent terminal,to achieve the user file life cycle protection and to ensure the security of data transmission.We take iOS client as an example for the model＇s functional test,which verifies its reliability in ensung data security of mobile terminal.
