Since nowadays mobile phone messages are flourishing, the
application of electronic coupon (e-coupon) will become a trend
for mobile users. E-coupon for mobile commerce can provide
mobility for users and distribution flexibility for issuers.
However, most of the existed e-coupon schemes usually apply
public-key cryptosystem to achieve the security, which will not
be implemented in mobile devices due to the complex
computations. In this paper, we propose a novel mobile e-coupon
system that just applies some simple cryptographic techniques,
such as one-way hash function and message authentication code.
In our system, the issuer can control the number of issued
e-coupons and prevent them from double-redeeming. The
merchant can verify the validity of the e-coupon and the
customers can securely transfer the e-coupon to others. The
customer does not need to perform any exponential computation
in redeeming and transferring the coupons.
