Weighted Attribute-based Encryption with Parallelized Decryption

Abstract

Unlike conventional ABE systems, which support Boolean attributes (with only 2 states: 1 and 0, or "Present" and "Absent"), Weighted Attribute-based Encryption schemes also support numerical values attached to attributes, and each terminal node of the access structure contains a threshold for a minimum weight. We propose a Weighted ABE system, with access policy of logarithmic expansion, by dividing each weighted attribute in sub-attributes. On top of that, we show that the decryption can be parallelized, leading to a notable improvement in running time, compared to the serial version.
