摘要： A method for random number generation includes generating random number sequences using a Random Number Generator (RNG) circuit having an externally-modifiable configuration. The RNG circuit generates a first random number sequence having a first measure of randomness, and modifies the configuration of the RNG circuit, causing the RNG circuit to generate a second random number sequence having a second measure of the randomness, indicating a degree of the randomness that is no less than the first measure.

摘要： A method for data integrity protection includes arranging in an integrity hierarchy a plurality of data blocks, which contain data. The integrity hierarchy includes multiple levels of signature blocks containing signatures computed respectively over lower levels in the hierarchy, wherein the levels culminate in a top-level block containing a top-level signature computed over the hierarchy. A modification to be made in the data stored in a given data block is received. One or more of the signatures is recomputed in response to the modification, including the top-level signature. Copies of the given data block, and of the signature blocks, including a copy of the top-level block, are stored in respective locations in a storage medium. An indication that the copy is a valid version of the top-level block is recorded in the copy of the top-level block.

摘要： A storage device and method for updating a shadow master boot record (MBR) are provided. In one embodiment, a storage device is provided having a memory with a first storage area and a second storage area. The storage device receives updated sectors of the shadow MBR from a host device and writes the updated sectors in the second storage area. The storage device determines a highest written sector in the first storage area that is occupied by the shadow MBR. The storage device copies the non-updated sectors of the shadow MBR from the first storage area to the second storage area, wherein only the non-updated sectors up to the highest written sector are copied. Accordingly, any non-updated sectors above the highest written sector are not copied from the first storage area to the second storage area. The storage device then designates the second storage area as storing a current version of the shadow MBR.

摘要： A method for data cryptography includes accepting input data, which contains a section that is to undergo a cryptographic operation and starts at an offset with respect to a beginning of the input data, by a Direct Memory Access (DMA) module. The input data is aligned by the DMA module to cancel out the offset. The aligned input data is read out of the DMA module, and the cryptographic operation is performed on the section.
