摘要： Techniques are presented for versioning files. Base files are acquired for files on a primary volume. At configurable points in time changes to the files are noted on different volumes, these changes are represented as deltas. The deltas are stored on an archive volume and represent versions and a version history for the files.

摘要： Techniques for assuring a receiver's non repudiation of a communication are provided via cooperation with a secure device. A secure device operates within a local environment of a receiver and exchanges certificates with a sender via the receiver. The sender encrypts data in a communication with the receiver. Separately, the sender sends an encrypted version of a decryption key to the receiver. The receiver presents the encrypted version of the key to the secure device and the secure device supplies the decryption key for use by the receiver to decrypt the previously sent encrypted data.

摘要： Systems and methods for extending and controlling access to a Common Information Model (CIM) are presented. According to an embodiment, access requests for a CIM object manager (CIMOM) pass through a CIM file system (CIMFS) where each access requested is authenticated. The CIMFS maintains and manages a hidden file system representing CIM classes and a CIM class hierarchy on a volume of storage. The structure, metadata, and values for the CIM classes, CIM object, and CIM providers are maintained in a hidden directory on the volume. This information is accessible via the CIMFS to use existing file system management operations.

摘要： Techniques are presented for randomly generating bits. A seed is inverted and a non repeating portion of the resulting digits from the inversion are retained. The inverted seed is then raised to a power to acquire another non repeating portion or additional digits. This process is repeated for a desired number of iterations. The resulting digits are then selectively combined to generate a stream of randomly generated bits with an infinite period.

摘要： Apparatus, systems, and methods may operate to taking a snapshot of an origin volume in conjunction with a backup process in response to receiving a snapshot request by a snapshot service. A persistent time stamp associated with the creation time of the snapshot may be recorded on the origin volume. The persistent time stamp is accessible to the file system process associated with the origin volume in most embodiments. If access to a file is requested, the time the file was last modified may be compared with the persistent time stamp, and if the file modified time is earlier than the persistent time stamp, the file's archive bit can be reset. Otherwise, the archive bit is not reset. Additional apparatus, systems, and methods are disclosed.

摘要： Replication techniques are presented. According to an embodiment of a method, a node of a replicated storage network is assigned to be an owner of a data block to issue write memory block commands. The network includes at least two nodes including the node assigned to be the owner. If a read memory block command is received to read the data block, a read_lock is issued for the data block, the data block is read, and the read_lock for the data block is released. If a write memory block command is received to write new data to the data block, a write_lock is issued for the data block, the data block is written and a version associated with the data block is incremented, and the write_lock for the data block is released.

摘要： Apparatus, systems, and methods may operate to assert a first semi-exclusive write lock with respect to a storage medium area by storing lock information when assertion of another semi-exclusive write lock with respect to the area is not detected. Additional activities may include writing data to the area by a writing entity that has asserted the first semi-exclusive write lock after determining the lock information has not changed, while substantially simultaneously de-asserting the first semi-exclusive write lock. Reading from the area may be determined as successful by determining that the semi-exclusive write lock was not asserted prior to or during the reading by checking the status of the lock information. Additional apparatus, systems, and methods are disclosed.

摘要： Apparatus, systems, and methods may operate to allocating encrypted memory locations to store encrypted information, the information to be encrypted and decrypted using a single hypervisor. Further activity may include permitting access to a designated number of the encrypted memory locations to a single application executed by an associated virtual machine (VM) subject to the hypervisor, and denying access to the designated number of the encrypted memory locations to any other application executed by the associated VM, or any other VM. In some embodiments, the operational state of the associated VM may be restored using the encrypted information. Additional apparatus, systems, and methods are disclosed.

摘要： Techniques are presented for secure broadcasting and multicasting. Communications for multicasting and broadcasting are encrypted and decrypted using a secure communication key. The secure communication key is represented in a broadcast value that is sent to selected parties. The broadcast value represents the product of unique prime numbers and an additional number plus the secure communication key. Each party is represented by one of the unique prime numbers. Each party can acquire the secure communication key by dividing the broadcast value by its particular prime number to obtain a remainder, which is the secure communication key.
