    摘要: A random number generator comprises random number generation circuitry to generate and output random bits. The random number generator comprises interface circuitry to receive and store random bits output by the random number generation circuitry and to output random bits. The interface circuitry prevents outputting the same random bits more than once.

    摘要: A random number generator includes a random bit source to generate random bits and circuitry to process the generated random bits to accumulate entropy in the generated random bits. The random number generator also includes circuitry to output processed random bits selectively such that at least one processed random bit is not output.

    摘要: A method for updating the content of EEPROM memory used for controlling processes run on a microprocessor used to control the operations of a long term memory array which includes moving an update process stored in the EEPROM memory to a random access memory associated with the microprocessor; and then using the update process stored in random access memory for erasing the contents of the EEPROM memory, and furnishing data to the microprocessor on a sector by sector basis from a host computer through an interface used by the microprocessor to provide data to the long term memory array. The data furnished by the host is written sector by sector to the EEPROM memory until the EEPROM memory has been updated.

    摘要: A protocol provides authentication of peripheral devices by a computing device to which the peripheral device connects. Computing devices include a verifier with a public key that authenticates multiple associated private keys. Private keys are embedded on peripheral devices. When the verifier is able to authenticate a connected peripheral, particular functionality is enabled that may not be enabled for peripherals that do not authenticate.

    摘要: A method and apparatus for producing a corrected bit stream from a random bit stream output by a random bit source. Sequential pairs of bits in the random bit stream are compared. If both bits in a pair of bits are identical, the output bits are discarded. If both bits in a pair of bits are different, one bit of the pair of bits is taken as the output bit.

    摘要: A method for monitoring the operations of a flash memory array divided into individually erasable blocks of memory in order to assure the integrity of data stored in the array in which each read or write operation is verified to detect an error which may have occurred in the operation including the steps of attempting at least one retry operation whenever an error occurs to determine whether the error is repeatable, marking the block to indicate valid data should be removed from the block if the error is found to be repeatable, removing the valid information from the block if the error is found to be repeatable, and removing a block with a repeatable error from operation.
