Branch target computation in secure start-up using an integrity datum and an adjustment datum

摘要

Embodiments related to conducting and constructing a secure start-up process are disclosed. One embodiment provides, on a computing device, a method of conducting a secure start-up process. The method comprises recognizing the branch instruction, and, in response, calculating an integrity datum of a data segment. The method further comprises obtaining an adjustment datum, and computing a branch target address based on the integrity datum and the adjustment datum.
