METHOD FOR VERIFYING AN APPLICATION PROGRAM BY USING DYNAMIC HASHING FOR RESETTING A START POSITION AND AN ENDING POSITION PER GENERATION OF HASH VALUE

摘要

PURPOSE: A method for verifying an application program by using dynamic hashing is provided to perform a dynamic hashing for generating different hash values, thereby accurately verifying the verification object application.;CONSTITUTION: A client sets a start position and an end position in an execution file for a verification object application (S100). The client generates a hash value by using the execution file with the start position and the end position (S200). The client encodes the hash value with a public key encoding method and transmits the hash value to a verification server (S300). The verification server decodes the hash value with the public key encoding method and verifies the verification object application (S400). The start position and the end position are reseted per generation of the hash value. The hash value is generated by using the start position and the end position.;COPYRIGHT KIPO 2013;[Reference numerals] (S10) Verification server and a client exchange a public key; (S100) Client sets a start position and an end position in an execution file for a verification object application; (S200) Client generates a hash value by using the execution file with the start position and the end position; (S300) Client encodes the hash value with the public key encoding method and transmits the hash value to a verification server; (S400) Verification server decodes the hash value with the public key encoding method and verifies the verification object application
