摘　　要：随着移动手持设备的普及,发行移动优惠券日益成为商家进行商业推广的一种重要举措。基于熟人口碑营销理念,首次提出一个离线可分享移动优惠券方案。采用近场通信(near field communication,NFC)技术和基于身份的公钥体制,方案能安全存储和传递优惠券。引入基于身份的代理授权机制实现安全创建并传递分享链,激励移动用户离线分享优惠券。结果分析表明,该方案具有正确性、不可伪造性、可验证性等安全属性,能有效地保护消费者和商家的利益。With the popularity of mobile devices,issuing mobile coupons （mCoupons）has increasingly become impor-tant 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 identity-based public key system were used to store and deliver mCoupons securely.By introduction of identity-based proxy au-thorization 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,unforge-ability,verifiability and so on,which protects interests of the consumers and the merchants.
