Efficient Data Integrity Verification Using Attribute Based Multi-signature Scheme in Wireless Network

摘要

Attribute based signature scheme is an important cryptographic primitive providing a powerful way for user to control their privacy. In wireless environment, the capacity of wireless channel is valuable resources which is limited. More information can be transmitted through the wireless channel when the cost of using signature to verify the message become less. In order to reduce the bandwidth needed to transmit attribute based signatures and keep signer's privacy, attribute based multi-signature scheme(ABMS) was proposed in this paper. Moveover, We formalized and constructed the ABMS. Our scheme is existentially unforgeable against chosen message attack and on Computational Diffie-Hellman(CDH) problem in the standard model. Analysis shows that our ABMS is more appropriate for wireless network to guarantee integrity of the data.
