Abstract:

Based on identity-based cryptography in cloud computing, we focus on the privacy protection of user identities in fuzzy identity-based encryption by considering the selection of threshold parameter δ as a problem of attribute relevance analysis. We also suggest a proposal to use random masking for keeping the privacy of user identities.

Key words: identity-based cryptography, public key infrastructure, cloud computing, attribute relevance analysis, random masking
