It is integrated with a mechanism to revoke the anonymity of credentials for resolving access disputes and making users accountable for their actions. The proposed scheme has a lower end-user computational complexity in comparison to existing credential schemes with delegatability and has a comparable level of performance with the credential standards of U-Prove and Idemix. Furthermore, we demonstrate how the proposed scheme can be applied to a collaborative e-health environment to provide its users with the necessary anonymous access with delegation capabilities.<\/jats:p>","DOI":"10.1145\/3338854","type":"journal-article","created":{"date-parts":[[2019,9,6]],"date-time":"2019-09-06T13:04:41Z","timestamp":1567775081000},"page":"1-22","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["An Anonymous Delegatable Attribute-based Credential Scheme for a Collaborative E-health Environment"],"prefix":"10.1145","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3623-3362","authenticated-orcid":false,"given":"Harsha S.
