摘要:

提出一个新的适用于移动云计算环境的完整性检测模型,在PDP模型中引入了拥有较强计算能力的代理签名方,代替移动终端生成数据验证标签。基于该模型设计了一个IBPS-PDP协议,该协议利用基于身份的签名方法,减少了系统的公钥证书管理和移动终端的证书认证代价。最后,证明IBPS-PDP在随机预言机模型下是安全的。

关键词: 移动云计算, 数据完整性, 基于身份签名, 代理签名

Abstract:

Based on provable data possession(PDP)model,a more perfect data integrity checking model for mobile cloud computing was proposed,in which there was an additional proxy party with stronger computing power to help the mobile users to calculate the block tags.Furthermore,for the proposed model,an identity-based proxy signature PDP(IBPS-PDP)protocol was presented.By using identity-based signatures,the system did not need to manage public key certificates and further the users did not need to take the additional computations to verify the other’s certificates yet.Finally,the security of the proposed IBPS-PDP protocol is proved in the random oracle model.

Key words: mobile cloud computing, data integrity, identity-base signature, proxy signature
