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 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.

摘要： A storage device and method for updating data stored in a partition of the storage device are provided. In one embodiment, a storage device is provided that contains a logical-to-physical address map and a memory with a first partition storing original data and a second partition. The storage device receives from a host device (i) a command to write updated data to a first logical address and (ii) a signature for verifying integrity of the updated data, wherein the first logical address is mapped to a physical address of the first partition. The storage device then stores the updated data in the second partition instead of the first partition and attempts to verify the signature of the updated data. If the attempt to verify the signature is successful, the storage device updates the logical-to-physical address map to map the first logical address to a physical address of the second partition.

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： A method and memory device for implementing long operations and supporting multiple streams are provided. In one embodiment, a memory device receives data and a command from a host to perform an operation on the data, wherein a time required for the memory device to complete the operation exceeds a maximum response time for the memory device to respond to the command. The memory device begins performing the operation on the data and, before exceeding the maximum response time and before completing the operation, sends the context of the operation to the host. At a later time, the memory device receives from the host: (i) a command to resume performing the operation and (ii) the context. The memory device then resumes performing the operation on the data based on the context received from the host.

摘要： A method for protecting information in a device includes providing a device with a non-secure hardware domain, a processor having a software-controlled mode of operation, and a secure hardware domain having a secure memory that is inaccessible by the processor when the processor is operating in the software-controlled mode of operation. Data from the non-secure hardware domain is established in the secure hardware domain. Computing operations are executed on the data in the secure hardware domain to produce a result. The secure hardware domain is purged, while retaining the result therein. The result is thereafter returned from the secure hardware domain into the non-secure hardware domain.
