Abstract

NON-REPUDIABLE LOG ENTRIES FOR FILE RETRIEVAL WITH SEMI-TRUSTED SERVER IS PROVIDED BY COERCING USER TO DIGITALLY SIGN THE LOG ENTRY ON THE EVENT THAT THE USER RETRIEVES A FILE FROM THE SERVER WHICH PREVENTS USER OR SERVER FROM INDEPENDENTLY FORGING OR MODIFYING A LOG ENTRY. THE SYSTEM (100) COMPRISING A USER INTERFACE MODULE (102A), A SERVER INTERFACE MODULE (104A), AN ASYMMETRIC ENCRYPTION MODULE (102C), A SYMMETRIC ENCRYPTION MODULE (102E), A DIGITAL SIGNATURE MODULE (102B), A COMBINER MODULE (102D), A REGISTRATION MODULE (104D) AND A LOG FILE (104G). THE ASYMMETRIC ENCRYPTION MODULE (102C) EXPLOITS KEY DUALITIES PROPERTIES BY ENCRYPTING MESSAGES USING PUBLIC KEY AND COMBINED PUBLIC KEY; AND DECRYPTING MESSAGES USING DECRYPTION KEY WHICH INCLUDES ONE SIGNATURE OR A COMBINATION OF SIGNATURES. THE METHOD OF FILE RETRIEVAL IS CONSTRUCTED SUCH THAT THE USER MUST SUBMIT THE FIRST SIGNATURE TO THE SERVER; THE USER MUST SIGN THE CORRECT LOG ENTRY RECORDING THE FILE RETRIEVAL. FURTHER, WHEN THE SERVER COMBINES THE FIRST SIGNATURE WITH ITS OWN SIGNATURE, THE COMBINATION FORMS ONLY PART OF THE DECRYPTION KEY. THE DECRYPTION KEY CAN BE COMPLETED ONLY BY USING THE USER’S SECOND SIGNING KEY WHEREBY THE SERVER CANNOT DECRYPT THE FILE AT ANY TIME. THE METHOD OF PROTECTION OF THE PRESENT INVENTION LIES IN THE COMBINATION OF SERVER’S AND USER’S DIGITAL SIGNATURES ON EVERY LOG ENTRY TO PROTECT AGAINST RECIPIENT OR USER WHO DENIES FROM RETRIEVING A FILE. THE MOST ILLUSTRATIVE DRAWING IS
