An apparatus that includes a substrate and a first plurality of circuit components mounted on the substrate, which is associated with a protected area. The apparatus includes a connector formed on the substrate to at least partially circumscribe the protected area and a second plurality of circuit components mounted on the substrate to at least partially circumscribe the connector to form a security barrier to physically inhibit a penetration attack into the protected area.

Physical barrier to inhibit a penetration attack

A technique includes providing a security monitor to at least detect a penetration attack on a circuit assembly that contains the security monitor. The technique includes inhibiting success of the penetration attack, including flexibly mounting the security monitor to the circuit assembly to allow the security monitor to move in response to the security monitor being contacted during the penetration attack.

Inhibiting a penetration attack

An example device in accordance with an aspect of the present disclosure includes an interleaved connector including a plurality of layers of conducting material interspersed with insulating material. A plurality of electrodes are to identify a change in capacitance of the interleaved connector to indicate a penetration of the device.

Detecting physical penetration of secure device

According to examples, an apparatus may include a security enclosure, a main processor housed in the security enclosure, and a physical security monitoring control unit (PSMCU) processor housed in the security enclosure. The PSMCU processor may cause the apparatus to switchably operate between a first mode and a second mode. In the first mode, the PSMCU processor may allow access by the main processor to a first cryptographic key while preventing access by the main processor to a second cryptographic key. In addition, in the second mode, the PSMCU processor may allow access by the main processor to the second cryptographic key while preventing access by the main processor to the first cryptographic key.

Separate cryptographic keys for multiple modes

A technique includes performing a plurality of instances of retrieving components of a security key from a plurality of locations of an electronic device and constructing the security key from the components. The technique includes inhibiting electromagnetic field-based eavesdropping from being used to reveal the security key, where the inhibiting includes varying a protocol that is used to retrieve the components among the instances.

Inhibiting electromagnetic field-based eavesdropping

Example embodiments relate to a shield for an electronic device. The shield may be shaped to enclose the electronic device. The shield may include a number of traces. Each trace may include an electrically conductive inner portion and an electrically non-conductive outer portion.

Shield for an electronic device

Lightweight wind deflectors having Mounting Sleeves attachable to Eyeglass Temple Stems. The Mounting Sleeves are flexible with rectangular cutouts running their lengths giving them the ability to attach or slide onto the Eyeglass Temple Stems. The Ear Flaps which deflect wind around the ears attach to Pressure Plate Hinge's, which establish and maintain pressure between the Ear Flaps and the wearer's cheekbones, they also allow lateral movement of the Ear Flap's for removal and placement on the head. Sleeve Shims can be installed into the rectangular cutouts of the Mounting Sleeves to compensate for different size eyeglass frames.
