A digital signature method based on CSK establishes a digital signature checking center on the website for checking the signature file. A client computer is established with a ciphering system and a digital signature protocol. Each subscriber is distributed with a hardware device of the cipher key. A signature subscriber uses the cipher key for executing digital signature to the file. The digital signature protocol adopts a combined symmetrical cipher technique for executing digital signature to the file and realizes that the signature cipher is different each time. A signature checking subscriber also uses a cipher key for checking the signature file. The digital signature checking center firstly checks the identity of the signature checking subscriber, and subsequently executes the checking to the signature file. The identity checking protocol and the digital signature checking protocol are all completed with a combined symmetrical key technique thereby realizing the digital signature of the file and the checking to the signature file.
