AB - In October, 2003, Duc. et al. proposed the new concept of a forward-secure blind signature scheme which preserves the validity of past signatures and which prevents a forger from forging past signatures even if the current secret key has been compromised. Today, to guarantee the quality of the growing and popular communication services on the Internet, it is necessary to reduce the computation load and communication costs for both parties of the signer and the requesters. This study proposes a new efficient method to implement the forward-secure blind signature. Because of its simple algorithm and fewer parameter requirements, our scheme is more efficient than Duc. et al.`s scheme. Moreover, only five modular multiplications are required for our key update procedure. The fast key update algorithm is very useful in some electronic applications.
