Abstract
Techniques for secure sharing of data in computing systems are disclosed herein. In one embodiment, a method includes when exchanging data between the host operating system and the guest operating system, encrypting, at a trusted platform module (TPM) of the host, data to be exchanged with a first key to generate encrypted data. The method also includes transmitting the encrypted data from the host operating system to the guest operating system and decrypting, at the guest operating system, the transmitted encrypted data using a second key previously exchanged between the TPM of the host and a virtual TPM of the guest operating system.
