METHOD AND APPARATUS FOR SECURE SOFTWARE UPDATE

摘要: There is provided methods and apparatuses for secure updating of firmware/software. The apparatus can be enabled by making use the Online Certificate Status Protocol (OCSP) to request revocation status certificates in certificate chain. In particular, a method called ‘OCSP stapling’ ensure validity or verify authenticity software/firmware. By virtue features OCSP stapling, user device does not need contact CAs directly purpose verifying that integrity delivered software/firmware thus required open an extra communication channel obtain certificates. This process also reduce burden on because are neither keep large volume CRLs nor maintain connection with devices which responsible.
