Forgery attacks on the ID-based multisignature scheme without reblocking and predetermined signing order
Recently, Chang et al. proposed an ID-based multisignature scheme based on RSA without reblocking and predetermined signing order. The scheme simplifies the public key certification process and overcomes the moduli clashes problem. In this paper, we show that the scheme is insecure against several forgery attacks.
