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 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 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 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.

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 for storing data includes providing a memory package including an integrated circuit containing a non-volatile memory and counter circuitry. The data is written to the non-volatile memory. The counter circuitry is operated to maintain a count of write operations performed on the non-volatile memory. The data and the count from the memory package are received at a controller, separate from the memory package, and the data is authenticated in response to the count.

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.
摘要翻译：通过将要存储在存储器中的加扰数据的组合和使用软件例程对数据的存储器地址进行加扰来执行加扰和解扰功能来防止针对计算设备的侧向信道攻击。通常在加密算法中使用的变量，数据和查找表的加密版本因此分散到伪随机位置。因此，需要依赖数据的内存访问的数据和加密原语可以防止可能暴露内存访问模式和危及加密密钥的攻击。
