A device includes one or more registers and circuitry. The circuitry subjects a key having a number of bits to a first function which takes a selection value into account, generating a result having a number of bits which is twice the number of bits of the key, and stores the result in the one or more registers. In response to a call for the key, the circuitry subjects the result stored in the one or more registers to a second function which takes the selection value into account to generate a response having a same value as the key.

Protection of registers against unilateral disturbances

A secure Universal Serial Bus (USB) storage device includes a memory controller capable of storing data in and retrieving data from a memory. The secure USB storage device also includes a USB secure microcontroller capable of authorizing access to the memory through the memory controller to thereby secure the memory. The USB secure microcontroller is also capable of protecting the data stored in the memory to thereby secure contents of the memory. The USB secure microcontroller could include an SPI interface and/or a GPIO interface emulating one or more of an SPI interface and an MMC interface to the memory controller. The memory controller could include an SPI interface and/or an MMC interface to the USB secure microcontroller. The secure USB storage device may be enumerated by a USB host controller under one or more device classes.

Secure universal serial bus (USB) storage device and method

The present invention is a smart card device that can be debugged and software developed using at least one interrupt endpoint without adding an additional port. At least one memory stores a debug monitor program and instructions for completing smart card transactions. An interface is defined by a plurality of communication pipes and respective endpoints, including at least one interrupt endpoint. A microprocessor is operatively connected to the interface and memory and configures the interrupt endpoint as a debug port for debugging and software development using the debug monitor program.

Smart card device and method for debug and software development

A system and method for transmitting and receiving secure e-mails is disclosed. A smart card device stores both private and public keys for an encryption algorithm. The smart card device is preferably a USB smart card device and interfaces a host having a client e-mail program. E-mails are transferred to and/or from the client e-mail program and e-mail server via the smart card while decrypting and encrypting any transmitted and/or received e-mails within the smart card device. The smart card device stores an IP address for an e-mail server. A Simple Mail Transfer Protocol outgoing parameter is set from the client e-mail program to an IP address for the smart card device.

Smart card device and method used for transmitting and receiving secure e-mails

An integrated circuit is used in a smart card device and includes at least one memory for storing mass storage data. The smart card device communicates through a chip/smart card interface (CCID) in accordance with the International Standards Organization 7816 (ISO 7816) protocol and a mass storage interface. A microprocessor is connected to the at least one memory and operative for initiating communications with the host using a CCID interface and transferring mass storage data using a mass storage interface.

Smart card device used as mass storage device

An integrated circuit for use with smart card and method are operative in both an ISO mode in accordance with the International Standards Organization 7816 (ISO 7816) protocol, and a non-ISO mode in accordance with a non-ISO protocol. The dual-mode integrated circuit includes a microprocessor and switching block. An external interface is connected to the switching block and includes an ISO port operative for communicating in an ISO mode when the ISO mode is detected and a non-ISO port operative for communicating in a non-ISO mode when a non-ISO mode is detected. The ISO port is configured to allow debugging and/or software development through a serial interface in a non-ISO mode and the non-ISO port is configured to allow debugging and/or software development through the non-ISO port in an ISO mode.
