Abstract
The present invention provides a kind of low computing capability equipment storage encryption method, includes the following steps, S1: memory space is carried out piecemeal according to preset space size；S2: system generates at random identical with the block number of institute's piecemeal in step S1 offsets to scale；S3: the data of each piecemeal are written in memory one by one according to offseting to scale；S4: when decryption or reading, memory is read one by one according to scale is offset to；S5: storage encryption is completed, the application is suitable for simple device element, for example fingerprint head acquisition module, the various kinds of sensors in smart home, such equipment are usually all that single-chip microcontroller/low side MCU is formed plus sensor sensor, computing capability is weak, but some important data, such as finger print information can be saved, the data such as networking key, encrypt the data of deposit simply using simple cipher mode, it is not easy to be cracked.
Description
[technical field]
The present invention relates to equipment storage cipher mode method and technology field more particularly to a kind of degree of safety are high, it is not easy to quilt
The low computing capability equipment storage encryption method cracked.
[background technique]
Smart machine largely uses at present, in store some important information in these equipment, such as personal information, close
Code, biometrics password etc. bring loss to other people if these data, which are stolen, to be illegally used.
Meanwhile the memory of many such equipment is very small, operational capability is very weak, is not available complicated encryption side
Formula, such as AES, and height is required to CPU computing capability, complexity is calculated, time, space requirement are big, so, if there is a kind of simple
Encryption storage method, safety can be greatly improved.
Based on this, those skilled in the art has carried out a large amount of research and development and experiment, and achieves preferable achievement.
[summary of the invention]
To overcome the problems of prior art, it is high that the present invention provides a kind of degree of safety, it is not easy to the low meter being cracked
It calculates capacity device and stores encryption method.
The scheme that the present invention solves technical problem is to provide a kind of low computing capability equipment storage encryption method, including following
Step,
S1: memory space is subjected to piecemeal according to preset space size；
S2: system generates at random identical with the block number of institute's piecemeal in step S1 offsets to scale；
S3: the data of each piecemeal are written in memory one by one according to offseting to scale；
S4: when decryption or reading, memory is read one by one according to scale is offset to；
S5: storage encryption is completed.
Preferably, each piece of size is 4K in the step S1.
Preferably, the data for needing to be stored in the memory space of the step S1 are as follows: 0x00 0x01 0x02 0x03
0x04 0x05 0x06 0x07 0x08 0x09；And every piece of storage size is 1Byte；The offset that system generates at random
Vector table is 5164289370；Then storage order are as follows: block 5 stores 0x00；Block 1 stores 0x01；Block 6 is stored
0x02；Block 4 stores 0x03；Block 2 stores 0x04；Block 8 stores 0x05；Block 9 stores 0x06；block 3
Store 0x07；Block 7 stores 0x08；Block 0 stores 0x09.
Compared with prior art, a kind of low computing capability equipment storage encryption method of the present invention is suitable for simple equipment device
Part, such as fingerprint head acquisition module, the various kinds of sensors in smart home, such equipment is usually all that single-chip microcontroller/low side MCU adds
Upper sensor sensor composition, computing capability is weak, but can save some important data, such as finger print information, networking key
Etc. data, using simple cipher mode make deposit data simply encrypted, it is not easy to be cracked.
[Detailed description of the invention]
Fig. 1 is a kind of flow diagram of low computing capability equipment storage encryption method of the present invention.
[specific embodiment]
To make the purpose of the present invention, technical solution and advantage are more clearly understood, with reference to the accompanying drawings and embodiments, to this
Invention is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, not
