Embodiment Construction

[0046] The method for implementing one-time programmable storage and the technical solution of the storage device will be described in detail below in conjunction with specific embodiments and accompanying drawings, so as to make it more clear.

[0047] Such as figure 1 As shown, in one embodiment, a method for realizing one-time programmable storage includes the following steps:

[0048] Step S110, when the logical address contained in the write command received by the storage device is within the logical address range of the preset storage area in the storage device, determine whether data has been written to the logical address contained in the write command, and if so, perform step S110. S120, if not, go to step S130.

[0049]Specifically, a preset storage area is divided in advance on the storage device, and a logical address range of the preset storage area is recorded. When the logical address contained in the received write command is within the logical address range...

Abstract

The invention relates to a one-time programmable storage implementation method and storage equipment. The method comprises the following steps of: when a logic address in a writing command which is received by the storage equipment is positioned in a logic address range of a storage area preset in the storage equipment, judging whether data are written at the logic address which is comprised by the writing command; if the data are written at the logic address which is comprised by the writing command, virtually executing the writing command; and if the data are not written at the logic address which is comprised by the writing command, executing the writing command, writing data, and recording the writing state of the logic address. By the method and the storage equipment, one-time programming storage of a boot program can be realized and other data can be stored in the same storage equipment, so that two kinds of storage devices are not required to store data respectively, hardware and hardware design cost can be saved, and the storage equipment has a simple structure.

Description

technical field [0001] The invention relates to the storage field, in particular to a method and a storage device for realizing one-time programmable storage. Background technique [0002] Most of the traditional system boot process is not directly completed by hardware, but needs to be completed on the basis of hardware through the cooperation of a boot program (also called a software program or a firmware program). If the boot program and the corresponding boot environment are themselves insecure, the system booted by the boot program may also be insecure. Such as Windows, Android and other systems, if their boot programs and related environments are maliciously modified, the booted system may run malicious programs. [0003] In order to avoid this situation, a method and device are needed to ensure that the boot program and the corresponding boot environment are authenticated and trusted. Booting achieved in this way is called trusted booting. [0004] In a trusted boo...
