US Patent 11514170 Secure boot of kernel modules

A computer-implemented method for providing a secured updated kernel module of an electronic device, wherein the method comprises the following steps: inserting by a computer a chameleon hash of a kernel module, a kernel module private key of the kernel module and an updated kernel module of the kernel module in a chameleon hash collision function thereby obtaining a collision data, combining by the computer, the updated kernel module with the collision data obtaining thereby a secured updated kernel module. Additionally, it is further described a computer-implemented method for secure updating at least one kernel module of an electronic device, a system comprising a server and an electronic device, computer programs and a computer-readable medium.
