Abstract

A system, method, and computer-readable medium are disclosed for providing enhanced security to a wireless monitor, comprising: establishing a connection between the wireless monitor from a first device; generating a session identification for a human interface design (HID) input after the connection is established, the session identification enabling activities of an I/O device to be accepted by the wireless monitor; encrypting the activities of the I/O device to provide encrypted I/O device activities; providing the encrypted I/O device activities to the first device; and, decrypting the encrypted I/O device activities at the first device.

Claims (12)

1. A computer-implementable method for providing enhanced security to a wireless monitor, comprising: establishing a connection between the wireless monitor from a first device; generating a session identification for a human interface design (HID) input after the connection is established, the session identification enabling activities of an I/O device to be accepted by the wireless monitor; encrypting the activities of the I/O device to provide encrypted I/O device activities; providing the encrypted I/O device activities to the first device; decrypting the encrypted I/O device activities at the first device; and, establishing a Miracast session between the wireless monitor and the first device after establishing the connection between the wireless monitor and the first device; and wherein the encrypted I/O device activities comprise a unique monitor generated random encryption key for each Miracast session, are not shared by client devices nor is derived from a pre-shared key (PSK) of the first device, and are distributed to the first device during a predetermined time after the Miracast session is established.

2. The method of claim 1 , wherein: the connection between the wireless monitor and the first device comprise communications corresponding to a WIFI-direct communication standard.

3. The method of claim 1 , wherein: the I/O device comprises at least one of a keyboard and a pointing device.

4. The method of claim 1 , wherein: encryption of the I/O device activities prevents unauthorized access to passwords that are communicated between the I/O device and the wireless monitor.

5. A system comprising: a processor; a data bus coupled to the processor; and a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for: establishing a connection between a wireless monitor and the system; generating a session identification for a human interface design (HID) input after the connection is established, the session identification enabling activities of an I/O device to be accepted by the wireless monitor; encrypting the activities of the I/O device to provide encrypted I/O device activities; providing the encrypted I/O device activities to the system; decrypting the encrypted I/O device activities at the system; and, establishing a Miracast session between the wireless monitor and the system after establishing the connection between the wireless monitor and the first device; and wherein the encrypted I/O device activities comprise a unique monitor generated random encryption key for each Miracast session, are not shared by client devices nor is derived from a pre-shared key (PSK) of the system, and are distributed to the system during a predetermined time after the Miracast session is established.

6. The system of claim 5 , wherein: the connection between the wireless monitor and the system comprise communications corresponding to a WIFI-direct communication standard.

7. The system of claim 5 , wherein: the I/O device comprises at least one of a keyboard and a pointing device.

8. The system of claim 5 , wherein: encryption of the I/O device activities prevents unauthorized access to passwords that are communicated between the I/O device and the wireless monitor.

9. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for: establishing a connection between the wireless monitor from a first device; generating a session identification for a human interface design (HID) input after the connection is established, the session identification enabling activities of an I/O device to be accepted by the wireless monitor; encrypting the activities of the I/O device to provide encrypted I/O device activities; providing the encrypted I/O device activities to the first device; decrypting the encrypted I/O device activities at the first device; and, establishing a Miracast session between the wireless monitor and the first device after establishing the connection between the wireless monitor and the first device; and wherein the encrypted I/O device activities comprise a unique monitor generated random encryption key for each Miracast session, are not shared by client devices nor is derived from a pre-shared key (PSK) of the first device, and are distributed to the first device during a predetermined time after the Miracast session is established.

10. The non-transitory, computer-readable storage medium of claim 9 , wherein: the connection between the wireless monitor and the first device comprise communications corresponding to a WIFI-direct communication standard.

11. The non-transitory, computer-readable storage medium of claim 9 , wherein: the I/O device comprises at least one of a keyboard and a pointing device.

12. The non-transitory, computer-readable storage medium of claim 9 , wherein: encryption of the I/O device activities prevents unauthorized access to passwords that are communicated between the I/O device and the wireless monitor.
