Anonymous Authentication Scheme for Smart Cloud Based Healthcare Applications

摘要: Many smart healthcare applications are adopting cloud to provide services patients. However, the sensitive data can be disclosed authentication server/service provider. Therefore, security and privacy crucial its success deployment at large scale. Patients don’t want disclose their identities server. One way protect from server is anonymous authentication. The process normally involves disclosing users’ private information, such as username password If patient linked or tracked by malicious adversaries requests, breached. Most of existing preserving health care provides anonymity adversaries. very few them In this paper, we have proposed a system which complete users our scheme, utilized rotating group signature scheme based on Elliptic curve cryptography To add an extra layer protection, used Onion Router network layer. performance evaluated theoretical analysis demonstrates that it resists various attacks several attractive features.
