Protecting persistent secondary platform storage against attack from malicious or unauthorized programs
A high integrity storage manager protects critical system files by maintaining a list of protected disk blocks in hardware, such as in a memory of a microcontroller.

During the suspension of the virtual machine on the active host server, dirty memory pages are copied to a ring buffer. A copy process copies the dirty pages to a first location in the buffer. At a predetermined benchmark or threshold, a transmission process can begin. The transmission process can read data out of the buffer at a second location to send to the standby host. Both the copy and transmission processes can operate substantially simultaneously on the ring buffer. As such, the ring buffer cannot overflow because the transmission process continues to empty the ring buffer as the copy process continues. This arrangement allows for smaller buffers and prevents buffer overflows.

The selection of the column or columns of the sub-matrix B which are to be shifted into the sub-matrix P is performed on the basis of the weight of the column which corresponds to the number of non-zero-entries in the column, and/or on the basis of the weight of the rows of the sub-matrix B connected to the column.

Value recycling facility for multithreaded computations
Solutions to a value recycling problem facilitate implementations of computer programs that may execute as multithreaded computations in multiprocessor computers, as well as implementations of related shared data structures.

Scalable and secure key management for cryptographic data processing
A method and system for secure and scalable key management for cryptographic processing of data is described herein. In the method, a General Purpose Cryptographic Engine (GPE) receives key material via a secure channel from a key server and stores the received Key encryption keys (KEKs) and/or plain text keys in a secure key cache. When a request is received from a host to cryptographically process a block of data, the requesting entity is authenticated using an authentication tag included in the request. The GPE retrieves a plaintext key or generate a plaintext using a KEK if the authentication is successful, cryptographically processes the data using the plaintext key and transmits the processed data. The system includes a key server that securely provides encrypted keys and/or key handles to a host and key encryption keys and/or plaintext keys to the GPE.
Method of modifying secrets included in a cryptographic module, notably in an unprotected environment
A method of modifying a set of secrets in a cryptographic module, to ensure that the modifying is either successful or invalid. The module includes readable version numbers for each secret and for the set of secrets. If the version number of the set of secrets is equal to a version number requiring the loading of a set of new secrets, the version number of the set of secrets of the cryptographic module is set to a distinctive number indicating that the cryptographic module is being reloaded. Next, for each secret, if the version number of the secret is different from the version number of the corresponding new secret to be loaded, the new secret and its version number are loaded. Next the version number of the set of secrets of the cryptographic module is set to the version number of the set of new secrets.
Full volume encryption in a clustered environment
Full volume encryption can be applied to volumes in a clustering environment. To simplify the maintenance of keys relevant to such encrypted volumes, a cluster key table construct can be utilized, where each entry of the cluster key table corresponds to an encrypted volume and comprises an identification of the encrypted volume and a key needed to access that volume. Keys can be protected by encrypting them with a key specific to each computing device storing the cluster key table. Updates can be propagated among the computing devices in the cluster by first decrypting the keys and then reencrypting them with a key specific to each computing device as they are stored on those computing devices. Access control requirements can also be added to the entries in the cluster key table. Alternative access control requirements can be accommodated by assigning multiple independent entries to a single encrypted volume.
