  • Publication number: 20240039714
    Abstract: Techniques are disclosed relating to relating to a public key infrastructure (PKI). In one embodiment, an integrated circuit is disclosed that includes at least one processor and a secure circuit isolated from access by the processor except through a mailbox mechanism. The secure circuit is configured to generate a key pair having a public key and a private key, and to issue, to a certificate authority (CA), a certificate signing request (CSR) for a certificate corresponding to the key pair. In some embodiments, the secure circuit may be configured to receive, via the mailbox mechanism, a first request from an application executing on the processor to issue a certificate to the application. The secure circuit may also be configured to perform, in response to a second request, a cryptographic operation using a public key circuit included in the secure circuit.

  • Publication number: 20200281686
    Abstract: A surgical site barrier which is smaller and provides for a sanitized area surrounding a surgical site or other wound, but which does not necessarily encompass the entire room or patient. Device is designed to site in close proximity to the patient and provide a frame with an opening where objects passing through the opening will first pass through an electromagnetic radiation (EMR) light wall and/or through an outward directed laminar airflow before being able to contact the wound.

  • Patent number: 8954740
    Abstract: A server receives identifying information of a user of a client device and data encrypted with a public key of a group, where the encrypted data includes an encrypted session key for secure content. The server determines whether the user is a member of the group using the identifying information of the user. If the user is a member of the group, the server decrypts the encrypted session key using a private key of the group, and causes the client device to obtain a session key to access the secure content.

  • Patent number: 7149020
    Abstract: A display system, apparatus and method for generating a visible pattern onto a display surface responsive to an audio frequency input signal by emitting a visible beam of light along a predetermined beam axis, interposing a reflector along the beam axis for reflecting the light beam to form a reflected beam directed generally towards the display surface, a pair of movable coils and a magnetizable element associated with each coil responsive to audio frequency input signals for movement of the reflector to generate a pattern on the display surface, supporting the reflector proximate to the pair of coils for movement of the reflector relative to the magnetizable elements, the predetermined beam axis having an angle of variation of the visible beam of light which is greater than zero degrees and less than ninety-degrees, and the visible beam of light is preferably a laser beam.
