A circuit chip and a method of operating it |
| abstract |
Secure patching of an operating system of the integrated circuit chip. A patch server encrypts a patch to the operating system of the integrated circuit chip and transmits the encrypted patch to an issuing-authority server. The issuing- authority server appends the encrypted patch into a digital certificate in an extension to the digital certificate and transmits the digital certificate including the encrypted patch to a terminal. The terminal transmits the digital certificate the integrated circuit chip. The integrated circuit chip recovers the extension to the second digital certificate and decrypts the extension using a decryption key of the manufacturer of the integrated circuit chip thereby recovering the patch to the operating system of the integrated circuit chip and installs the patch into the operating system of the integrated circuit chip. |
