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 method for protection of data includes maintaining a control parameter indicative of a current version of the data. The data is partitioned into multiple segments. Respective signatures of the segments are computed, responsively to the control parameter, the segments and respective signatures forming respective signed input segments, which are stored in a memory. After the signed input segments are stored, a signed output segment is fetched from the memory. The signature of the signed output segment is verified responsively to the control parameter, and the data in the signed output segment is processed responsively to verifying the signature.

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.

摘要： A method and apparatus for masking messages subject to exponentiation in a secure cryptographic device subject to a chosen-message attack for the purpose of discovering secret exponent information through non-invasive physical testing of the cryptographic device. Through the use of Montgomery arithmetic, a random multiplicative factor is applied to the input message, and can be easily removed without having to compute the inverse of the random factor, as is necessary with prior-art masking techniques. This masking complements and enhances the natural masking inherent in the use of Montgomery arithmetic. The method of the persent invention is ideally suited to Montgomery arithmetic processors, but is not limited thereto, and can be used in combination with other security techniques.

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 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 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. Blocks are stored in respective first locations in a storage medium. A modification to be made in the date 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 second locations in the 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.
