Abstract
A method supports secure input/output (I/O) communications between an I/O device and a data processing system via a keyboard, video, and mouse (KVM) switch. An example embodiment includes the operations of establishing a first secure communication channel between the KVM switch and the I/O device and establishing a second secure communication channel between the KVM switch and the data processing system. In addition, I/O data may be received at the KVM switch from the I/O device via the first secure communication channel. In response to receipt of the I/O data from the I/O device, the I/O data may be transmitted from the KVM switch to the data processing system via the second secure communication channel. Embodiments may also include support for non-secure channels between the KVM switch and nonsecured I/O devices, nonsecured data processing systems, or both.
