The invention relates to the field of information technology safety, and in particular provides a method for an information security device for binding network software. The method comprises the following steps that: a service end generates corresponding accounts and keys according to a hardware identification number of the information security device, writes the hardware identification number, the corresponding accounts and keys into a network software database, and writes the accounts and keys into the information security device; specific information is written into the information securitydevice, and the specific information is network software characteristic information and / or service end characteristic information; and a user acquires the information security device with the accounts, the keys and the specific information, installs the software, uses the software by using the specific information in the information security device, and uses the accounts and the keys in the information security device to carry out authentication. The binding method greatly improves the safety of the information security device.
