Title:
Mitigating the One-Use Restriction in Attribute-Based Encryption
Authors: Lucas Kowalczyk, Jiahui Liu, Kailash Meiyappan, Tal Malkin
Abstract:We present a key-policy attribute-based encryption scheme that is adaptively secure under a static assumption and is not directly affected by an attribute “one-use restriction.” Our construction improves upon the only other such scheme (Takashima '17) by mitigating its downside of a ciphertext size that is dependent on the maximum size of any supported attribute set.
