Revocation of Direct Anonymous Attestation
2011Direct Anonymous Attestation (DAA) is a special type of anonymous digital signatures, used by the Trusted Computing Group (TCG) for the purpose of computer platform attestation whilst preserving platform anonymity. Like any other anonymous cryptographic primitives, how to efficiently revoke an existing member who is no longer legitimate, is an ...

Attribute-Based Encryption Supporting Direct/Indirect Revocation Modes
2009Attribute-based encryption (ABE) enables an access control mechanism over encrypted data by specifying access policies among private keys and ciphertexts. In this paper, we focus on ABE that supports revocation. Currently, there are two available revocable ABE schemes in the literature.

Enhanced Privacy ID: A Direct Anonymous Attestation Scheme with Enhanced Revocation Capabilities
IEEE Transactions on Dependable and Secure Computing, 2007Direct Anonymous Attestation (DAA) is a scheme that enables the remote authentication of a Trusted Platform Module (TPM) while preserving the user's privacy. A TPM can prove to a remote party that it is a valid TPM without revealing its identity and without linkability. In the DAA scheme, a TPM can be revoked only if the DAA private key in the hardware

Revocation of Advance Directives
2013The freedom to revoke advance directives is an integral part of any legal regulation or ethical theory of such documents, just as informed consent for treatment or research also entails the possibility of withdrawing consent at any time. While advance directives are legally regulated in most developed countries, the conditions for revocation are ...

Competency for creation, use, and revocation of psychiatric advance directives.
The journal of the American Academy of Psychiatry and the Law, 2007Psychiatric advance directives help promote patient involvement in treatment and expedite psychiatric care. However, clinicians are unsure of how to use directives, partly due to poor clarity regarding standards for capacity to create, use, and revoke them. This article recommends possible capacity standards.

An Access Control Scheme with Direct Cloud-Aided Attribute Revocation Using Version Key
2014Cloud storage allows owners to host their data in the cloud, and provides users with online access anywhere and anytime. With CP-ABE, data owners are allowed to specify policy autonomously, which can realize fine-grained access control. However, some important problems have not been yet effectively solved: 1) Low efficiency for attribute revocation. 2)

Leakage-resilient ciphertext-policy attribute-based encryption (LR-CP-ABE) is an important tool to achieve fine-grained access control of data and resist side-channel attacks. Privacy protection and user revocation are two practical problems it faces. However, most of the existing schemes fail to achieve user revocation while protecting user’s privacy ...
