摘　　要：本文提出了一种基于GSM移动环境的微支付方案,它通过将计算、存储和通信量转移到静态的网络主机上使得移动电话的负荷最小化。在整个支付过程中,移动电话发送和接收的信息非常简单,且避开了复杂的公钥运算,减少了系统延时并消除了因通信失败而造成不完全支付的可能性。同时,本方案使用会话密钥对交易信息进行加密,保护了移动用户隐私和支付信息的安全。与其它移动微支付方案相比,由于本方案完全没有使用公开密钥算法,因而效率大大提高。此外,方案还为移动用户提供了有限的匿名性。In this paper,we propose a micropayment scheme designed for use in a GSM mobile environment,where the overload of computation,storage and communication for mobile phone is reduced by directing operations normally per- formed by the mobile user to the static portion of the network. Messages received and sent during the payment are very simple and public key infrastructure is not needed,which reduces delay and removes the possibility of incomplete payment protocols due to communications failures. Furthermore,all the information with regard to payment is en- crypted by a shared symmetric key in our scheme,where the privacy of the mobile user is protected and the security of information is guaranteed. Compared with other mobile micropayment schemes in existence,no public-key operation is required, which minimizes the computation and storage overhead dramatically. In addition, restricted anonymous is provided in our scheme.
