摘要： Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and/or data structure to render the program more difficult to understand and/or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and/or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.

摘要： Selecting a segment boundary within block b is disclosed. A first anchor location j|j+1 is identified wherein a value of f(b[j−A+1 . . . j+B]) satisfies a constraint and wherein A and B are non-negative integers. A segment boundary location k|k+1 is determined wherein k is greater than minimum distance from j.

摘要翻译： 公开了在块b内选择段边界。 识别第一锚定位置j | j + 1，其中f（b [j-A + 1 ... j + B]）的值满足约束，并且其中A和B是非负整数。 确定分段边界位置k | k + 1，其中k大于距j的最小距离。

摘要： Systems and methods are disclosed for providing a trusted database system that leverages a small amount of trusted storage to secure a larger amount of untrusted storage. Data are encrypted and validated to prevent unauthorized modification or access. Encryption and hashing are integrated with a low-level data model in which data and meta-data are secured uniformly. Synergies between data validation and log-structured storage are exploited.
