Each record (instance, example) is assumed to belong to a predefined class, as determined by one of the attributes. Abstract. Attribute-based encryption (ABE) is a public-key- based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes. A promising application of ABE is flexible access control of encrypted data stored in the cloud, using access polices and ascribed attributes associated with private keys and .
