YCT14 KP-ABE scheme is broken #8

Closed adelapie closed 2 years ago

adelapie commented 2 years ago

Hello,

The YCT14 scheme was broken in [1] and a 'fixed' version was again broken in [2]. We have demonstrated how the attack can be implemented in practice in https://www.blackhat.com/eu-21/briefings/schedule/index.html#practical-attacks-against-attribute-based-encryption-25058.
