Özet

Rivest and Shamir presented two simple micropayment schemes, "PayWord" and "MicroMint," for making small purchases over the Internet [14]. Recently, Adachi et al. have pointed out that the PayWord scheme has two security problems, and proposed a new micropayment scheme to overcome these problems [1]. Nevertheless, we show that their protocol is still vulnerable to impersonation and replay attacks.
