Comments on “Certificateless Short Aggregate Signature Scheme for Mobile Devices”
Je Hong Park, Bonwook Koo · IEEE Access · 2024
In the paper "Certificateless Short Aggregate Signature Scheme for Mobile Devices" a pairing-based certificateless aggregate signature (CLAS) scheme was proposed. Although the authors claim that their CLAS scheme is secure and provide a mathematical proof to support this, we show that anyone can create an aggregate signature on any set of messages without the participation of other users.
