摘要： Advanced Encryption Standard (AES) is an encryption algorithm for securing sensitive unclassified material by U.S. Government agencies and, as a consequence the de facto encryption standard for commercial applications worldwide. Performing concurrent error detection (CED) for protection of such a widely deployed algorithm is an issue of paramount importance. We present a low-cost CED method for AES. In this method, we make use of invariance properties of AES to detect errors. For the first time, the invariance properties of the AES, which are for the most part used to attack the algorithm, are being used to protect it from fault attacks. Our preliminary ASIC synthesis of this architecture resulted in an area overhead of 13.8% and a throughput degradation of 16.67%.

摘要： Generally described, embodiments of the present invention provide a system and method for determining what files of a consumer computer should have protection copies included in a backup and what files should be excluded from the backup. Additionally, embodiments of the present invention provide a method and system for recovering files and/or directories from multiple types of temporal versions, such as backup copies and total copies, and also provide the ability to recover from either local temporal versions or remote temporal versions. Still further, embodiments of the present invention provide the ability to only create a protection copy for a portion of a file that has changed since a previous protection copy of a file was created and stored.
