Abstract
Methods and systems may include a computing system having a display, a display controller with a decryption module, and a security element with security logic. The security logic can be configured to establish a secure path between the secure element and the display in response to a secure output mode request, wherein the secure path includes the display controller. In addition, the security logic may be configured to prevent the decryption module from being bypassed, and transmit encrypted data from the secure element to the display via the secure path.
