摘要:

针对没有第三方参与认证智能卡存储的访问密钥随注册云的个数增加而线性增长的问题,提出一种多云环境下基于智能卡的认证方案。该方案在无第三方参与认证下,智能卡只需存储2个访问密钥就能实现用户与多个云服务器之间的身份认证,有效地减少了智能卡的存储费用。由于没有使用公钥密码技术,而是利用 XOR 同态函数和散列函数生成认证信息,从而有效降低了智能卡和云服务器的计算费用。此外,所提方案也不需要在多云端存储任何用户的信息,降低了云服务器的存储和管理费用。安全性分析和性能分析表明,所提方案能抵御多种攻击,是一个安全、高效的方案。

关键词: 多云环境, 身份认证, 智能卡, XOR同态函数

Abstract:

To solve the problem of the access keys stored in a smart card increasing linearly with the number of registered clouds without third party participated in authentication,an authentication scheme was proposed for multi-cloud environment based on smart card.In the proposed scheme,the authentication was realized between user and multiple clouds without third party participation when the smart card only stored two access key.Thus the storage cost of smart card was reduced effectively.Because there was no public key cryptography,the authentication messages was generated by using XOR homomorphic function and Hash function,thus the computational cost of the smart card and the cloud servers was reduced effectively.Moreover,the proposed scheme also didn’t need to store any user’s information on the cloud servers,thereby reducing the storage and management costs of the cloud servers.The security analysis and the performance analysis show that the proposed scheme is able to resist multiple attacks,which is secure and efficient.

Key words: multi-cloud environment, identity authentication, smart card, XOR homomorphic function
