摘要： Systems and techniques of the present disclosure may provide remote debugging of an integrated circuit (IC) device while preventing unauthorized access of device intellectual property (IP). A system may include an IC device that generates an encrypted session key and an interface that enables communication between the IC device and a remote debugging site. The interface may enable the IC device to send the encrypted the encrypted session key to initiate a remote debug process, receive an acknowledgement from the remote debugging session, and authenticate the acknowledgement. Further, the interface may enable to the IC device to initiate a secure debug session between the IC device and the remote debugging site.

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 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： 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： 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.
