摘要： A processor-based method for verifying a secured file, directory, or meta-data, comprising: extracting a persistent, independent signature for a secured file, directory, or meta-data from a directory signature file, the signature identifying a certificate identifier, a hash algorithm identifier, and an encrypted hash value for that secured file, directory, or meta-data; retrieving a public key corresponding to the certificate identifier; decrypting the encrypted hash using the public key and a decryption tool, resulting in a clear text hash value; creating a new hash value for the secured file, directory, or meta-data, the hash creation corresponding to the hash algorithm identifier; and verifying the signature when the new hash value for the secured file, directory, or meta-data matches the unencrypted hash value from the persistent, independent signature for the secured file, directory, or meta-data,

摘要： A processor-based method for securing directories through a persistent signature, comprising: selecting a directory; selecting a private key, a certificate identifier and a hash algorithm identifier for each selected directory; creating an encrypted hash of the directory using the hash algorithm and private key; and creating a persistent, independent signature for the directory that identifies the directory, certificate identifier, hash algorithm identifier, and the encrypted hash value for that directory.

摘要： A processor-based method of creating a secondary index for a B-tree in a database includes creating an empty secondary index; traversing the B-tree to find the left most data page to begin processing; capturing the current system time; placing a read-lock on the data page; retrieving a first primary key value for the data page; writing the first primary key value to a control information for the B-tree; creating a secondary index entry and writing it into the secondary index; and releasing the read-lock.

摘要： The present disclosure relates generally to computer architecture and infrastructure for guest operating systems executing on a host operating system. A method of compiling and executing a new program in a secure sandbox. The method includes receiving, by a host operating system, a request from a guest operating system to invoke an execution environment in a secure sandbox on a host operating system; and execute the execution environment in the secure sandbox. The user can use the execution environment in the secure sand box from a guest operating system to compile and execute the new program on the host operating system.

摘要： Virtual machines in a network may be isolated by encrypting transmissions between the virtual machines with keys possessed only by an intended recipient. Within a network, the virtual machines may be logically organized into a number of community-of-interest (COI) groups. Each COI may use an encryption key to secure communications within the COI, such that only other virtual machines in the COI may decrypt the message. Remote devices may gain access to virtual machines in a network through a virtual device relay. The virtual device relay receives data from the remote device, such as a tablet or cellular phone, and forwards the data to one of the virtual machines, when the virtual device relay shares a COI with the destination virtual machine.

摘要： Systems and methods for obtaining access to database files m a computing system. A method may include receiving a first call from a database management system requesting access to a database file. The method may further include transmitting a second call to an operating system interface requesting that a memory-mapped data expanse file be created. The method may also include receiving a first address representing the database file in response to successful mapping of the database file to the memory-mapped data expanse file located at the operating system interface.

摘要： A method and system for providing a plurality of host systems shared access to data files from a file server. The method includes monitoring a control file for updates, the control file located within a corresponding host directory located within the file server; receiving a request for access to a data file stored on the file server, the access request being written to the control file, the access request including a requested data file operation; performing the requested data file operation in response to the control file being updated with the access request; creating a status file in the host directory in which the requested data file operation was performed upon completion of the requested data file operation; writing status data in the status file, the status data including a result of the performance of the requested data file operation; and allowing access to the host directory in which the requested data file operation was performed in response to the status data being written to the status file.
