Below by drawings and the specific embodiments, technical scheme of the present invention is described in further detail.
Embodiment one
The embodiment of the present invention provides a kind of method of protection information safety, and as shown in Figure 1, described method mainly comprises the following steps:
Step 101, the device port of devices encrypt self;
In this step, equipment before activation, the password of device port can be pre-set, the password of described device port is the character string generated according to cryptographic algorithm, and by device port instruction write device, as in the encrypted file system (EFS, EncryptingFileSystem) of write device.
Equipment is when starting, and can be encrypted the device port of self, described device port can comprise: diag port, AT port and modulation modem port etc.; Described equipment can comprise: data card, focus product etc.The device port of described devices encrypt self, comprising:
Equipment, when starting, is preset the encryption identification flag of described device port, the state of described encryption identification flag is set to effective status.
Wherein, the effective status of described encryption identification flag can be: the value of encryption identification flag is set to 1; Correspondingly, the disarmed state of described encryption identification flag can be: the value of encryption identification flag is set to 0.
Particularly, such as, when described device port is diag port, the password of described diag port can be pre-set, the password of described diag port is the character string generated according to cryptographic algorithm, and by diag instruction write device, as in the encrypted file system EFS of write device.
Described devices encrypt diag port comprises:
Equipment, when starting, is preset the encryption identification flag of described diag port, the state of described encryption identification flag is set to effective status.
Here, the encryption flow of described equipment to AT port and modem port is identical with to the encryption flow of described diag port, is not repeating at this.Wherein,
When equipment operation goes wrong, user is by the running log of described diag port capture apparatus, thus analyze and solve problem; Or when user wants to check or revise device interior parameter, also realize by described diag port.
Described user can send the control of the aspects such as AT instruction is carried out calling out, note, phone directory, data service, fax by AT port.
Described user can also carry out dialing by modem port and set up Microsoft Loopback Adapter.
Step 102, equipment determines that the instruction received is decryption instructions, and when determining that the password in described decryption instructions is consistent with the password of setting, carries out port operation to described device port;
In this step, after device start, when receiving the instruction that user inputted by man-machine interface, judge whether described instruction is decryption instructions, when determining that described instruction is decryption instructions, extract the password in described decryption instructions, password in described decryption instructions is mated with the password of setting, judge that whether the password in described decryption instructions is consistent with the password of setting, when determining that the password in described decryption instructions is consistent with the password of setting, the state of described encryption identification flag is set to disarmed state, port operation is carried out to described device port; Wherein, describedly port operation carried out to described device port comprise: checked by described diag port or information in amendment equipment, capture apparatus running log; Or undertaken calling out by described AT port, the control of note, the aspect such as data transmission; Or set up Microsoft Loopback Adapter by described modem port dialing.The password of described setting can be: the password prestored in the encrypted file system EFS of equipment.
In addition, when described equipment determines that the password of password in described decryption instructions and setting is inconsistent, then by man-machine interface to user's prompt cipher mistake, described device port still keeps encrypted state, to prevent from being modified information.
Here, when the instruction that equipment determines reception is not decryption instructions, whether judgment device port is in encrypted state;
Particularly, when determining that described instruction is not decryption instructions, whether judgment device port is in encrypted state comprises: whether the state judging described encryption identification flag is effective status, when the state determining described encryption identification flag is effective status, namely representing now device port is encrypted state.
