  • Detecting physical penetration of secure device
    Patent number: 10963594
    Abstract: 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.
    Type: Grant

  • Separate cryptographic keys for multiple modes
    Patent number: 10742412
    Abstract: 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.
