Yuan Bian-qin · Journal of Shandong University · 2014
With the popularity of mobile devices,issuing mobile coupons( mCoupons) has increasingly become important for the merchants to promote their business. Based on the idea of word of mouth marketing between acquaintances,an offline sharable mCoupons scheme was proposed firstly. Near field communication( NFC) technology and identitybased public key system were used to store and deliver mCoupons securely. By introduction of identity-based proxy authorization mechanism,a shared chain which can encourage mobile users to share their mCoupons offline was created and transferred securely. Analysis shows that the scheme satisfies many security properties such as correctness,unforgeability,verifiability and so on,which protects interests of the consumers and the merchants.
