摘要： A method and storage device for using file system data to predict host device operations are disclosed. In one embodiment, a storage device is disclosed having a first memory storing data and file system metadata, a second memory, and a controller. In response to receiving a command from the host device to read a first address in the first memory, the controller reads data from the first address in the first memory and returns it to the host device. The controller predicts a second address in the first memory to be read by a subsequent read command from the host device, reads the data from the predicted second address, and stores it in the second memory.

摘要： A method for random number generation includes generating random number sequences using a Random Number 5 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 counting device includes a set of memory cells, including multiple groups of the memory cells configured to store count words of a count code, which include a less significant word and a more significant word. A controller assigns first and second groups of the memory cells to store the less significant word and the more significant word. The controller increments the less significant word from an initial value up to a first limit in each plurality of successive first iterations and increments the more significant word from an initial value up to a second limit in each of a plurality of successive second iterations in response to reaching the first limit. Upon reaching the second limit, the controller makes a new assignment of the groups of the memory cells that are to store the less significant word and the more significant word.

摘要： A first storage device provides a host device with access to a private memory area by communicating a password between the first storage device and a second storage device via the host device using a double-encryption scheme. In one embodiment, a host device receives a twice-encrypted password from a first storage device, sends the twice-encrypted password to a second storage device, receives a once-encrypted password from the second storage device, decrypts the once-encrypted password to obtain the password, and sends the password to the first storage device. In another embodiment, a first storage device sends a twice-encrypted password to a host device, receives the password from the host device after the twice-encrypted password is decrypted by a second storage device and the host device, and provides the host device with access to the private memory area only if the password matches one that is stored in the first storage device.

摘要： Side channel attacks against a computing device are prevented by combinations of scrambling data to be stored in memory and scrambling the memory addresses of the data using software routines to execute scrambling and descrambling functions. Encrypted versions of variables, data and lookup tables, commonly employed in cryptographic algorithms, are thus dispersed into pseudorandom locations. Data and cryptographic primitives that require data-dependent memory accesses are thus shielded from attacks that could reveal memory access patterns and compromise cryptographic keys.

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 signed multiplication method and a corresponding device for multiplying a first multiplicand with a second multiplicand. The device stores the first multiplicand in a first register as a first vector of at least one respective digit and storing the second multiplicand in a second register as a second vector of at least one respective digit, each digit having a pre-determined number of bits. The method further converts the digits of the first vector and the second vector to corresponding digits of one bit less each than the pre-determined number of bits. A processor effects signed multiplication of the multiplicands.
