摘要： An encoding technique of the invention protects software programs and hardware designs from being copied, tampered with, and its functions from being exposed. The software programs and hardware designs (collectively called programs) thus encoded still remain executable. The encoding technique employs the concept of complexity of programs and produces proximity inversion in terms of functions contained in the programs, while preserving the behaviors. Various embodiments are possible to achieve this encoding which includes, for example, cascading and intertwining of blocks of the programs.

摘要： Methods and devices for thwarting code and control flow based attacks on software. The source code of a subject piece of software is automatically divided into basic blocks of logic. Selected basic blocks are amended so that their outputs are extended. Similarly, other basic blocks are amended such that their inputs are correspondingly extended. The amendments increase or create dependencies between basic blocks such that tampering with one basic block's code causes other basic blocks to malfunction when executed.

摘要： A method for rendering software resistant to reverse engineering. Replace at least one first constant (mathematical expression, etc.) in a computational expression with a second mixed mathematical and bitwise-Boolean expression, the first constant being simpler than the second expression and the second expression being based on the value or the variables found in the first constant (or expression). Evaluation of the second mixed mathematical and bitwise-Boolean expression produces a value preserving the value of the first constant, either: with the original value of the first constant or the original value of the result of the first expression, in which case the second mixed mathematical and bitwise-Boolean expression is obtained from the first constant by converting the first constant by mathematical identities; or, in an encoded form, as a new value, which can be converted back to the original value of the first constant by applying an information-preserving decoding function, in which case the second mixed mathematical and bitwise-Boolean expression is obtained from the first constant by modifying the first constant by a combination of conversion according to mathematical identities and transformation according to an information preserving encoding function.

摘要： A method and system for renewing software at the component-level is provided. A client program includes a base component for loading a software component into at least one loadable region of the program to update the program. Code in the software component is for writing state data associating the state of the update in storage, upon execution of the software component, and testing the state data to verify condition of the updated program and disallowing rollback and roll-forward attacks, the state data comprising hash chain values. The state data for verifying the correctness of the updated program is entangled with application data used for the program functionality. A server includes: an update pool having a plurality of software updates deployed in each client, and a policy control for monitoring and controlling at least one of: the length of time the client runs until the software update is invoked, a chain of the updates; and the granularity of the update.

摘要： Systems and methods for unattended authentication of software applications to provide these applications with access to shared resources. A server password manager (SPM) module resident on a node also occupied by a requester software application requesting access to resources receives the requestor's request. The SPM module creates a request package containing the requestor's information as well as the node's identifying information. The request package is then transmitted to a credentials manager (CM) module in a CM node. The request package, encrypted by the SPM module with encryption keys previously generated by the CM module, is decrypted by the CM module. The contents are checked against data stored by the CM module regarding the SPM module and the requestor application when these were registered with the CM. If the data matches, then the CM provides credentials which are used to give the requestor application access to the requested resources.

摘要： A method to secure a non-native application. The non-native application is processed to obtain an application stub to be triggered within a virtual machine. The processing of the non-native application also provide a native code function upon which the application stub depends. The non-native function is part of a trusted module that extends security services from the trusted module to the virtual machine. The trusted module is a native code application that creates a trusted zone as a root of trustiness extending to the virtual machine by an execution-enabling mechanism between the application tab and the non-native function.
