AI‐Based Immortality: The Ethical Advantage of the Aretai Approach
AI &Innovation, EarlyView.ABSTRACT The convergence of artificial intelligence, digital identity technologies, and biogerontological ambitions has produced a novel set of philosophical problems that have not yet been adequately addressed within mainstream bioethical discourse. Digital life extension—encompassing AI‐generated avatars, neural data preservation, mind uploading, and

Make Revocation Cheaper: Hardware-Based Revocable Attribute-Based Encryption
2024 IEEE Symposium on Security and Privacy (SP)As an advanced one-to-many public key encryption system, attribute-based encryption (ABE) is widely believed to be a promising technology for achieving flexible and fine-grained access control of encrypted data on untrusted storage servers (e.g., public cloud servers). However, user revocation in ABE is a critical but challenging problem, and designing

Server-Aided Revocable Attribute-Based Encryption
, 2016 As a one-to-many public key encryption system, attribute-based encryption (ABE) enables scalable access control over encrypted data in cloud storage services. However, efficient user revocation has been a very challenging problem in ABE. To address this issue, Boldyreva, Goyal and Kumar [5] introduced a revocation method by combining the binary tree ...

Time-based and privacy protection revocable and traceable data sharing scheme in cloud computing
Tongxin xuebao, 2021 General ciphertext-policy attribute-based encryption (CP-ABE) provides fine-grained access control for data sharing in cloud computing, but its plaintext formed access policy may cause leakage of private and sensitive data.And revoking a malicious user ...

Fast Revocation of Attribute-Based Credentials for Both Users and Verifiers [PDF]
Computers & Security, 2015 Attribute-based credentials allow a user to prove properties about herself anonymously. Revoking such credentials, which requires singling them out, is hard because it is at odds with anonymity. All revocation schemes proposed to date either sacrifice anonymity altogether, require the parties to be online, or put high load on the user or the verifier ...

Efficient revocable attribute-based encryption scheme
Tongxin xuebao, 2019 In the existing solutions,the time-based scheme is difficult to achieve immediate revocation,and the third-party-based scheme often requires re-encryption,which needs large amount of calculation and doesn’t apply to mas-sive data.To solve the problem,an ...
