An Outsourced Attribute-Based Encryption Scheme Supporting Attribute Revocation [PDF]
Traditional Ciphertext-Policy Attribute-Based Encryption(CP-ABE) schemes have large computational overhead in key generation,decryption and attribute revocation processes.Aiming at this problem,this paper proposes an outsourced CP-ABE scheme which ...

Attacking Pairing-Free Attribute-Based Encryption Schemes
Combining several results that have been published in the last years, it is known that it is impossible to design simple and secure attribute-based encryption schemes that work in (classical) settings like the RSA or the pairing-free discrete logarithm ...

Flexible Attribute-Based Encryption [PDF]
In this paper, we propose a notion of flexible attribute-based encryption. Flexible attribute-based encryption is a variant of ciphertext-policy ABE, which allows one to loosen a decryption policy underlying a given ciphertext, if one knows some system-wide trapdoor information, without knowing its underlying plaintext message.

ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Targeted Homomorphic Attribute-Based Encryption
In key-policy attribute-based encryption ABE, messages are encrypted respective to attributes x, and keys are generated respective to policy functions f. The ciphertext is decryptable by a key only if $$fx=0$$fx=0. Adding homomorphic capabilities to ABE is a long standing open problem, with current techniques only allowing compact homomorphic ...
