ABSTRACT
With the rapid development of Internet and mobile communication, more and more people begin to buy electronic products through the Internet and mobile phone, usually, only small electronic cash payment is used in shopping, for example, when browsing certain webpage, the users only need to pay a few cents to businesses, if we still use the original macro payment mode in the transaction, it will not embody the characteristics of micropayment. If we use the RSA signature technology to guarantee the security of the transaction, according to reference [2], we can see that the Hash function is 100 times faster than the RSA signature, and about 1000 times faster than the RSA signature generation, so the transaction efficiency will be low in the use of RSA to ensure the security of transactions.
