Abstract: In order to resolve the problem of limited resources of mobile terminal devices in mobile computing services environment, an improved privacy-preserving authentication scheme with hierarchical access control is proposed based on signcryption technology and multi-server authentication technology. Users can access multiple mobile cloud service providers by only registering arbitrary one of them, and the authentication process does not require the participation of a trusted third party. Besides, mobile terminals do not use the bilinear pairing operation to avoid high computational complexity. Performance analysis results show that the computing efficiency of the proposed scheme in mobile terminals can be improved by about 34% compared with the existing related schemes, providing practical value in improving the access efficiency of cloud services.
