| Summary: | The signature schemes based on RSA and ECC do not seem suitable for special application area such as wire-less sensor network, smart card and wireless RFID since they suffer from low computing efficiency. In order to design a scheme for small computing devices with limited computing capacity, Wang et al. proposed a novel lightweight digital signature scheme based on the hash authentication technology. A polynomial time algorithm, which found an equivalent signing secret key from the public key, was presented or this novel lightweight digital signature scheme. By using the equivalent secret key, adversary can forge signature for arbitrary messages. Hence, their digital signature scheme based on hash authentication is broken. |
