Example

[0023] See also Figure 1-Figure 3 As shown, this embodiment provides a one-way data secure transmission optical communication device, including a storage component 1, a processing component 2 and an external interface 3, the external interface 3 is electrically connected to an external device, the processing component 2 processes the data passing through the external interface 3, and the storage component 1 stores the data received by the processing component 2. The improvement of this case is that when the processing component 2 receives the data transmitted from the external interface 3, the data is encrypts and after the data is encrypted, the data is transmitted to the storage component 1, the storage component 1 marks the transmitted data and temporarily stores it, and when the external interface 3 is electrically connected to another device, the storage component 1 checks the temporarily stored data and formally stores the temporarily stored data after the check is completed.

[0024] By encrypting the data transmitted into the processing component 2 and temporarily storing the data after encryption, the situation of missing data area during data transmission is avoided. At the same time, when the external interface 3 and the external device are connected again, the storage component 1 reviews the temporarily stored data and stores it after the review is completed, so as to ensure the security of the stored data during the transmission process and ensure the normal use of the communication device.

[0025] The specific details of the communication device are detailed below. The processing component 2 includes a main control circuit 21, a decryptor 22 and a path controller 24. The decryptor 22 is electrically connected to the decryptor 22, the path controller 24 is electrically connected to the decryptor 22, and the path controller 24 is electrically connected to the external interface 3. The data in the storage component 1 is transmitted to the main control circuit 21, so that the processing component 2 obtains the information data stored in the storage component 1. The main control circuit 21 verifies the data transmitted by the storage component 1, determines the content of the transmitted data, and transmits it to the decryptor 22 after the verification is completed. The decryptor 22 decodes the data verified by the main control circuit 21, and the decoded data is transmitted from the decryptor 22 to the path controller 24. The path controller 24 determines the path of the transmitted data and transmits the data to the external interface 3 after determination. The data is transmitted to the external device through the external interface 3.

[0026] At the same time, the storage component 1 includes a memory 11 and a data transmitter 12, the memory 11 and the data transmitter 12 are electrically connected, and the data transmitter 12 and the main control circuit 21 are electrically connected, and the data in the memory 11 are transmitted to the decryptor 22 through the data transmitter 12 and the main control circuit 21, and the effect of data transmission in the communication device is completed.

[0027] In the process of a communication device receiving data from an external device, viruses may exist in the data. The viruses entering the communication device may damage the data stored in the communication device, causing the data stored in the communication device to be missing. In order to improve the security of data transmission by the communication device, the improvements in this case are as follows: the processing component 2 also includes an encryptor 23, which is electrically connected to the main control circuit 21 and the path controller 24 respectively. The path controller 24 receives data transmitted by the external interface 3, and the path controller 24 determines the transmission path according to the source of the data transmission. At this time, the data is transmitted from the external interface 3, and the path controller 24 transmits the data to the encryptor 23, which encrypts the data, and the encrypted data is transmitted to the main control circuit 21, and the main control circuit 21 transmits the compressed data to the storage component 1 for storage.

The data register 14 electrically connects the memory 11 and the data receiver 13 together, and the data receiver 13 and the main control circuit 21 are electrically connected together. The data encrypted by the encryptor 23 is transmitted to the data register 14 through the main control circuit 21 and the data receiver 13 for temporary storage. The data register 14 continues to mark the temporarily stored data. When the external interface 3 is connected to the external device again, the data register 14 detects the temporarily stored data. When the data is detected to be qualified, the detected data is transmitted to the memory 11.

[0029] The data transmitted into the communication device is compressed by the provided encryptor 23, and then the compressed data is transmitted to the data temporary register 14, and the data is temporarily stored by the data temporary register 14. When the external interface 3 on the communication device and the external device are connected again, the temporarily stored data is stored in the memory 11. By temporarily storing the data, the storage time of the data is extended, and it is avoided that the data transmitted into the communication device carries a virus and damages the data in the communication device, thereby improving the security of one-way data transmission.
