Attribute-based encryption enables fine-grained control of encrypted data [SW05]. In a ciphertext-policy ABE (CP-ABE) scheme [GPSW06], for instance, ciphertexts are attached to access policies and keys are asso
In a sense, attribute based encryption generalizes asymmetric cryptography: the communication is no more 1:1 and the sender (encrypting) could ignore the users allowed to receive (decrypt) her messages. An example: document sharing Assume a company wants to manage the access to certain documents ...
Attribute-Based Encryption (ABE) is a known cryptographic primitive that enables fine-grained access control over encrypted data. However, currently the existing ABE schemes do not meet NIST’s ABAC requirements or are not computationally efficient enough for IoT applications. In this paper, we ...
