Privacy-preserving authentication of trees and graphs

  title={Privacy-preserving authentication of trees and graphs},
  author={Ashish Kundu and Elisa Bertino},
  journal={International Journal of Information Security},
Secure data sharing in third-party environments such as the cloud requires that both authenticity and confidentiality of the data be assured, especially when such structures encode sensitive information (such as in XML documents). Existing authentication schemes for trees and directed acyclic graphs (DAGs) are authenticity-preserving, but not confidentiality-preserving, and lead to leakage of sensitive information during authentication. In this paper, we propose a family of three leakage-free… CONTINUE READING
