Abstract
Official abstract text for this publication.
An encryption and decryption methods applied on an operating system kernel are disclosed, where a hash result is obtained from a computation between a booting program and the operating system kernel by using a definition table, the computation result is combined with the operating system kernel for encryption of the operating system kernel, and the operating system kernel may not be decrypted and thus booted whenever the booting program, the operating system kernel or the two combined are falsified or replaced, whereby the technical efficacy which the booting program and the operating system kernel are authenticated bilaterally for safety booting may be achieved.
First claim
Opening claim text (preview).
What is claimed is: 1. An encryption method applied on an operating system kernel, being suitable for use on a device having a booting program and the operating system kernel stored therein, comprising steps of: pre-establishing a definition table in the booting program, the definition table having codes stored therein; selecting randomly a plurality of codes from the definition table by the booting program and recording the plurality of codes having been selected by the booting…
