Abstract
A method and apparatus for securely updating and booting a code image is provided, where a code image is updated in a storage medium storing an operating system having a first region, on which a boot code is loaded, a second region, in which a first code image is stored, and a third region, in which the boot code and first check data for verifying the first code image are stored. Updating a code image includes storing a second code image in the second region, extracting information about a secure one-way function from the first check data, and generating second check data for verifying the second code image using the extracted information of the secure one-way function and storing the generated second check data in the third region. When the second check data is set as a parameter of the secure one-way function, the first check data is generated.
