  • Patent number: 11924964
    Abstract: Devices and methods are described for reducing etching due to Galvanic Effect within a printed circuit board (PCB) that may be used in an electronic device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trace. The contact finger is configured to couple the electronic device to a host device. The contact trace is electrically isolated from the rest of the PCB circuitry during a fabrication process by a separation distance between an exposed portion of the contact trace and an impedance trace. The contact finger and the exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to the impedance trace using a solder joint.

  • Patent number: 8135132
    Abstract: A system and method are described supporting secure implementations of 3DES and other strong cryptographic algorithms. A secure key block having control, key, and hash fields safely stores or transmits keys in insecure or hostile environments. The control field provides attribute information such as the manner of using a key, the algorithm to be implemented, the mode of use, and the exportability of the key. A hash algorithm is applied across the key and control for generating a hash field that cryptographically ties the control and key fields together. Improved security is provided because tampering with any portion of the key block results in an invalid key block. The work factor associated with any manner of attack is sufficient to maintain a high level of security consistent with the large keys and strong cryptographic algorithms supported.
