It can be understood that, in step 201, it can be ensured that the transmission information is stolen during the connection process between the remote mobile phone and the local mobile phone, thereby preventing the service related to the secret information from being utilized by a lawbreaker.
In one embodiment, the local first terminal forwards only the keypad code sent by the remote terminal to the local second terminal; the remote terminal and the local first terminal are both smart phones, and the local second terminal is a computer.
The above technical features have been explained and exemplified in detail in the system for implementing a remote security keyboard, and will not be described herein again.
The embodiment of the present invention further provides a specific implementation manner of a method for implementing a remote security keyboard, where the method is applied to a local second terminal, and referring to fig. 3, the method specifically includes the following steps:
step 300: a keypad code sent by the remote terminal and forwarded by the local first terminal is received.
Step 400: and judging whether the keyboard code is correct or not, and forwarding a judgment result to the remote terminal from the local first terminal.
In one embodiment, the local first terminal is connected to the local second terminal through a USB data line, and monitors the keyboard code.
It should be noted that the local first terminal does not perform network communication or USB network sharing with the local second terminal, but only simulates the standard keyboard of the local second terminal, thereby achieving isolation of the mobile internet environment from the local second terminal stand-alone (or intranet).
In an embodiment, the storage mode of the local first terminal is random access.
A Random Access Memory (RAM), also called a main Memory, is an internal Memory that directly exchanges data with the CPU. It can be read and written at any time (except for refreshing), and has high speed, and is usually used as a temporary data storage medium of an operating system or other programs in operation. The RAM can write (store) or read (take out) information from any one of designated addresses at any time when it is operated. The biggest difference with the ROM is the volatility of data, i.e. the stored data will be lost as soon as power is turned off. The local mobile phone adopting the random access mode can bring the following beneficial effects: the program of the local mobile phone does not reserve any keyboard information transmitted by the remote mobile phone, so that the local mobile phone cannot acquire the keyboard input information after the operation is finished, and the security of the high-level authority confidential information is ensured.
In one embodiment, the monitoring the keypad code comprises:
and controlling the communication connection with the local first terminal in real time according to the sending speed of the keyboard code and/or the proportion of the control code in the character stream.
It can be understood that the input of the keyboard code is initiated by the user, if the input speed of the keyboard code is too fast (exceeds a preset value), the operation is determined to be illegal, the local second terminal immediately cuts off the communication connection with the local first terminal to ensure information security, and in addition, whether the keyboard code is illegal or not can be determined according to the occupation ratio of the control code in the character stream (in the transmission process, the most basic unit of transmission data is the character stream).
To further explain the scheme, the invention provides a specific application example of the method for implementing the remote secure keyboard by taking the bank large-amount storage service as an example, and the specific application example specifically includes the following contents, and refer to fig. 4.
In this specific application example, the local mobile phone corresponds to the local first terminal, the to-be-received password computer corresponds to the local second terminal, and the remote mobile phone corresponds to the remote terminal.
S0: and connecting the local mobile phone with the password computer to be received.
Specifically, local personnel access a local handset to the computer system via a USB cable. It should be noted that the local mobile phone does not perform network communication or USB network sharing with the to-be-received password computer, but only simulates the standard keyboard of the to-be-received password computer, thereby achieving isolation of the mobile phone internet environment from the single computer (or internal network) of the to-be-received password computer.
S1: and carrying out encrypted connection on the remote mobile phone and the local mobile phone.
In order to ensure reliability and safety, the encryption mode comprises an external U shield, a built-in U shield based on a TEE and SE chip security certificate, a soft certificate and the like. It can be understood that step S1 can ensure that the transmission information is stolen during the connection between the remote handset and the local handset, thereby avoiding the use of the service related to the password by the lawbreaker. It can be understood that the remote keyboard operator acquires the screen information of the to-be-received password computer by means of the camera of the local mobile phone, instead of acquiring the screen information by connecting the to-be-received password computer through a network, so that the local mobile phone is only one keyboard under the control of a program, and can also undertake the work of all local USB interface keyboards.
S2: and the supervisor inputs the required password of the password computer to be received through the remote mobile phone.
The remote mobile phone needs to be provided with a remote program, and the remote program needs to accept the keyboard input of the mobile phone and encrypt the keyboard code with an encryption medium. Meanwhile, the video conversation can be carried out with the other side, and the image of the computer screen of the other side can be seen. The local program uses the encryption medium to decrypt after receiving the data, and simulates a physical keyboard to send keyboard codes to the USB port. And simultaneously, starting a mobile phone camera to acquire a local computer screen image.
S3: the local mobile phone decrypts the password and transmits the password to the computer.
In step S2 and step S3, the keyboard (or the simulated keyboard of the mobile phone) code of the remote personnel is transmitted to the local mobile phone by way of encrypted communication of the mobile phone under the transmission of the encrypted network, the local mobile phone is connected to the USB interface of the computer by using the USB communication line, and the encrypted information transmitted from the remote mobile phone is decrypted, so as to transmit the encrypted information to the local computer in the original keyboard code form, thereby realizing the remote operation of the computer.
A supervisor acquires screen information by means of a camera of the local mobile phone and does not connect with a local computer through a network to acquire the screen information, so that the local mobile phone is only a keyboard under the control of a program and can bear the work of all local USB interface keyboards. In addition, the program of the local mobile phone does not reserve any keyboard information transmitted by the remote mobile phone, so that the local mobile phone cannot acquire the keyboard input information after the operation is finished, and the safety of the high-level authority password is ensured. Of course, the local personnel must also be reliable, otherwise he can disconnect the communication and take over the operation using the physical keyboard after entering the specific user remotely.
As can be seen from the above description, the method for implementing a remote security keyboard provided in the embodiments of the present invention uses a mobile phone to simulate a standard computer keyboard to remotely control a computer. The typical scene is that high-authority control personnel access a keyboard into a mobile phone through a USB port at other places and remotely work through the mobile phone; local personnel access the local mobile phone to the computer system through a USB line, and receive a keyboard coding instruction of the remote mobile phone by using the wireless network to drive the computer to work. Under the transmission of an encryption network, the keyboard (or the mobile phone simulation keyboard) code of a remote person is transmitted to a local mobile phone in a mobile phone encryption communication mode, the local mobile phone is connected to a computer USB interface by a USB communication line, and the encryption information transmitted by the remote mobile phone is decrypted, so that the original keyboard code form is transmitted to a local computer, and the remote operation of the computer is realized. On the premise of ensuring safety, the invention realizes the convenience and high efficiency of remote operation of password input in the fields of finance and communication, and saves time and cost.
