Abstract: Systems, apparatuses and methods may provide for verifying, from outside a trusted computing base of a computing system, an identity an enclave instance prior to the enclave instance being launched in the trusted computing base, determining a memory location of the enclave instance and confirming that the memory location is local to the computing system. In one example, the enclave instance is a proxy enclave instance, wherein communications are conducted with one or more additional enclave instances in the trusted computing base via the proxy enclave instance and an unencrypted channel.

Abstract: One embodiment provides an apparatus. The apparatus includes an input output memory management unit (I/O MMU), a non-secure operating system (OS) driver, a secure OS driver and a virtual machine monitor (VMM). The I/OMMU is to couple an I/O Controller to a memory. The I/O Controller is coupled to a secure device and a non-secure device and has one I/O Controller identifier. The non-secure OS driver is associated with the non-secure device. The secure OS driver is associated with the secure device. The VMM is to allocate a secure address space to a secure OS and a non-secure address space to a non-secure OS. The secure address space is non-overlapping with the non-secure address space.

Abstract: Disclosed in some examples are devices, methods, and machine-readable mediums for reliable control of IR LEDs. In some examples, a microcontroller running firmware controls whether the LED is activated or not by use of a disable signal. The microcontroller enables or disables the operation of the LED based upon a user's proximity to the LED, a watchdog timer, and a confirmation that only trusted software is executing.

Abstract: Technologies for end-to-end biometric-based authentication and locality assertion include a computing device with one or more biometric devices. The computing device may securely exchange a key between a driver and a secure enclave. The driver may receive biometric data from the biometric sensor in a virtualization-protected memory buffer and encrypt the biometric data with the shared key. The secure enclave may decrypt the biometric data and perform a biometric authentication operation. The computing device may measure a virtual machine monitor (VMM) to generate attestation information for the VMM. A secure enclave may execute a virtualization report instruction to request the attestation information. The processor may copy the attestation information into the secure enclave memory. The secure enclave may verify the attestation information with a remote attestation server. If verified, the secure enclave may provide a shared secret to the VMM. Other embodiments are described and claimed.

Abstract: Systems and techniques for privacy protected input-output port control are described herein. In an example, an indication may be obtained that a protected port is disabled. A set of application attributes stored in a secure memory location may be compared to a set of attested application attributes to create a verification flag. At least one port attribute of the protected port may be obtained based on the verification flag. The protected port may be enabled using the at least one port attribute. Other examples, for controlling an input-output port using computer firmware and trusted execution techniques are further disclosed.

Abstract: This disclosure pertains to iris recognition including liveness testing. A device may perform iris recognition with testing to check liveness. Sensing circuitry in the device may comprise an IR sensor and IR emitter to generate a uniform IR emission and a pulsed IR emission. Sensor data based on the uniform IR emission may be used for iris recognition, which may be confirmed by at least one test confirming that real eyes are being analyzed and not spoof data. For example, a determination may be made as to whether a light reflection is visible in images captured by the IR sensor, whether the light reflection is aligned and/or synchronized with an eye center and/or iris center, whether a portion of the iris visible in the captured images changes from image to image, whether the images show that a pupil of the eye is reactive to the pulsed IR emissions, etc.

Abstract: A hardware platform includes a nonvolatile storage device that can store system firmware as well as code for the primary operating system for the hardware platform. The hardware platform includes a controller that determines the hardware platform lacks functional firmware to boot the primary operating system from the storage device. The controller accesses a firmware image from an external interface that interfaces a device external to the hardware platform, where the external device is a firmware image source. The controller provisions the firmware from the external device to the storage device and initiates a boot sequence from the provisioned firmware.
