| 20100304061 | FABRICATION OF HIGH ASPECT RATIO FEATURES IN A GLASS LAYER BY ETCHING - Methods, apparatuses, systems, and devices relating to the fabrication of features for semiconductor devices are disclosed. The features may include vias and pillars. In some implementations, the vias may define light pipes for semiconductor image sensor devices that serve to guide electromagnetic radiation directly down to photodiodes or other radiation detecting elements formed on an underlying silicon substrate. These structures significantly improve the light collection efficiency and reduce the scattering and crosstalk losses in the dielectric layer. An etch mask may be used to produce features through a subsequent etching process. More specifically, the etch mask defines sidewalls in the glass layer, provides excellent dry etch resistance, and enables easy lift-off of the etch mask from the glass layer. Two embodiments are disclosed herein: the first using amorphous silicon as the etch mask; and the second employing a photoresist as the etch mask. Both embodiments produce high aspect ratio features having generally vertical and smooth sidewalls. | 12-02-2010 |

| 20080270791 | Method and Apparatus for Remote Administration of Cryptographic Devices - Techniques are disclosed for performing operations in an authentication token or other cryptographic device in a system comprising an authentication server. In one aspect, a code generated by the authentication server is received in the cryptographic device. The code may have associated therewith information specifying at least one operation to be performed by the cryptographic device. The cryptographic device authenticates the code, and responsive to authentication of the code, performs the specified operation. If the code is not authenticated, the operation is not performed. The code may be determined as a function of a one-time password generated by the authentication server. The function may also take as an input an identifier of the operation to be performed. | 10-30-2008 |
| 20080320555 | RESET-TOLERANT AUTHENTICATION DEVICE - An authentication device comprises a processor having a reset input, a trigger source coupled to the reset input of the processor, and interface circuitry for outputting codes generated by the processor. The trigger source may comprise, for example, a trigger button having an associated switch that when actuated supplies a reset to the reset input. The processor is configured to analyze a given reset applied to the reset input to determine if the reset is an inadvertent reset or a reset generated by the trigger source. The processor generates a code responsive to the reset if the reset is determined to be a reset generated by the trigger source. The code may be supplied to a host device which communicates the code to an authentication server for authentication. | 12-25-2008 |
| 20090006858 | Secure seed provisioning - A method is used for secure seed provisioning. Data is derived from inherent randomness in an authentication device. Based on the data, the authentication device is provisioned with a seed. | 01-01-2009 |
| 20110246778 | PROVIDING SECURITY MECHANISMS FOR VIRTUAL MACHINE IMAGES - A method for providing a security mechanism for validating and executing a virtual machine image where the virtual machine image is obtained from an external source to run on an endpoint or host system. An electronic device storing validation data is connected to the host system, and the virtual machine image is validated with the validation data. The virtual machine image run on the host system if validated and/or decrypted. The electronic device can be a USB flash drive, and the electronic device can include a security processor with memory in addition to having a display, keypad, token, or any combination thereof. The validation data utilized may comprise a keyed hash or digital signature when validating the virtual machine image. | 10-06-2011 |
