The architecture of coupon-based, semi-off-line, anonymous micropayment system for internet of things

Abstract

In the Internet of Things a lot of business opportunities may be identified. The devices in IoT may create ad-hoc temporary networks to provide services or share some resources. Such services are characterized by a great economical potential, especially while provided at mass-scale and for incidental users. However, the development of paid services or resources in IoT is hampered by relatively big transaction costs of payment operations. To deal with this problem, we propose a novel architecture of coupon-based, semi-off-line, anonymous micropayment system to enable transactions in the scope of Internet of Things. User anonymity and security is assured by the usage of standard cryptographic techniques together with novel architectural design of the payment processes. Utilization of a hash function allows generating and verifying electronic coins in computationally efficient way, so as to be executed even in hardware- and software-restricted environment such as Internet of Things.
