Wireless communication techniques provide convenience for users to get desired information. Construction and management costs of information provision systems with low computational-ability devices, such as RFID devices, are low so lightweight authentication protocols are required for information security. In this paper, two lightweight authentication protocols are proposed for reliable information provision systems with low computational-ability devices. The first protocol is for public information, and the other ensures that only authorized users can get information.

Electronic commerce (e-commerce) is a relatively new, emerging and constantly changing area of business management and information technology. One of the technological innovations in banking, finance and e-commerce is the electronic cash (e-cash) transfer system. E-cash transfer systems refers to the technological breakthrough that enables us to perform financial transactions electronically. In this paper we propose a secure e-cash transfer system based on the elliptic curve cryptography. In order to protect the honest participants of the e-cash system we use an elliptic curve blind signature scheme and also we need a trusted third party to trace the criminals.
