A METHOD OF CONTROLLING LICENSE KEY GENERATION

摘要

A method of generating software license connecting security token and making request to client system via communication module that security token contains first verification information pack, encrypted using secret key, including primary digital identity of software vendor generated based on hardware information of security token. First digital counter; extracting hardware information of security token to generate secondary digital identity; decrypting first verification information pack using secret key to gain access of primary digital identity and digital counter; verifying primary digital identity is similar to secondary digital identity; decrypting second verification information pack, containing tertiary digital identity and second digital counter; generating copy of license key upon verifying the primary and tertiary digital identities are same; generating third digital counter; encrypting third digital counter together with primary or tertiary digital identity using secret key to produce third verification information pack; replacing first and second verification information pack with third verification information pack.
