20100223403INTEGRATED CIRCUIT CARD INTERFACE DEVICE WITH MULTIPLE MODES OF OPERATION - An integrated circuit (IC) card interface device with multiple modes of operation allows communications with numerous IC cards, including smart cards. An interface device according to the present invention can be used several different ways, including: connected to a host device (such as a person computer); in a standalone configuration; and as a flexible platform upon which future applications can be based, since it can be easily reprogrammed and upgraded. The interface device can contain an application engine and an I/O module, providing a flexible architecture and allowing several different operating modes. In connected mode, the interface device can, for example, be connected to a PC to enable the use of smart cards in secure applications. In standalone mode, the interface device can provide information about smart cards with which it interfaces. Programming mode enables the host device or the smart card itself to update or upgrade the programs available within the interface device. When being updated or upgraded, the source of the programming can be from a host device or from the smart card, adding further flexibility to the use of such an interface device.09-02-2010
20080263371PROTECTED VOLUME ON A DATA STORAGE DEVICE WITH DUAL OPERATING SYSTEMS AND CONFIGURABLE ACCESS AND ENCRYPTION CONTROLS - A method provides a protected region of a data storage device associated with a computational device, where data in the protected region is primarily protected by preventing access without proper access authorization. The method comprises the steps of providing, in an unprotected region of the data storage device, a first operating system and associated operating system data; monitoring operating system data accessed by the computational device until a predetermined functionality becomes available; storing, in the protected region, the monitored operating system data; providing, in the protected region, a second operating system; transferring control of the computational device from the first operating system to the second operating system; storing data in the protected region; and preventing access to the stored data in the protected region without access authorization. In a further embodiment of the method, the second operating system optionally provides a second level of security by preventing decryption of data stored in the protected region without decryption authorization.10-23-2008
20080263363Portable Data Encryption Device with Configurable Security Functionality and Method for File Encryption - A portable encryption device with logon access controlled by an encryption key, with an on board cryptographic processor for reconstituting the encryption key from a plurality of secrets generated by a secret sharing algorithm, optionally shrouded with external secrets using an invertible transform resistant to quantum computing attacks. Another embodiment provides file decryption controlled by a file encryption key, with the on board cryptographic processor reconstituting the file encryption key from a version of the file encryption key which has been shrouded with a network authorization code. A method for encryption of a plaintext file by hashing, compressing, and encrypting the plaintext file, hashing the ciphertext, hashing the plaintext hash and the ciphertext hash, and sealing the ciphertext together with the resulting hash. A portable encryption device for performing the method is also disclosed.10-23-2008
