Described is a system for training a neural network for estimating surface normals for use in operating an autonomous platform. The system uses a parallelizable k-nearest neighbor sorting algorithm to provide a patch of points, sampled from the point cloud data, as input to the neural network model. The points are transformed from Euclidean coordinates in a Euclidean space to spherical coordinates. A polar angle of a surface normal of the point cloud data is estimated in the spherical coordinates. The trained neural network model is utilized on the autonomous platform, and the estimate of the polar angle of the surface normal is used to guide operation of the autonomous platform within the environment.

Described is a system for enforcing software policies. The system transforms an original software by inserting additional instructions into the original software. The additional instructions have the effect of determining, at run-time, whether proceeding with execution of the original software is in accordance with a predefined policy. Transforming the original software relies on software analysis to determine whether any run-time checks normally inserted into the original software can be safely omitted. The transformed software prevents unauthorized information from passing to the network.

Described is a system for anonymous job allocation and majority voting in a cloud computing environment. The system broadcasts a job to physical nodes, each of the physical nodes having a control operations plane (COP) node and one or more service nodes associated with the COP node. A set of redundant job assignments is distributed to individual COP nodes pursuant to a private job assignment schedule, such that each individual COP node is only aware of its own assignment and corresponding job. The service nodes execute the job assigned to the COP nodes such that the service nodes each complete a task associated with the job and forward an individual result to their associated COP node. A privacy-preserving result checking protocol is performed amongst the COP nodes such that secret shares of a majority result are obtained and the majority result is provided to a client.

Anonymous allocation and majority voting in a compromised environment

The system is directed to a plurality of nodes in a network and a process by which the nodes reach a consensus ordering of broadcast messages. For example, one or more nodes proceed by agreeing on an order of two or more broadcast message derived events A and B. If a node sees event A longer than a time period (T6) before seeing event B, then the node outputs 'A consensus-before B' as a consensus broadcast ordering. If the node sees the event A and not the event B after waiting at least T6, then the node outputs 'A consensus-before B' as a consensus broadcast ordering. However, if the node sees both events A and event B within T6, then the node broadcasts a request for a vote on message ordering, executes a consensus broadcast reception protocol for the votes, and makes an ordering decision based on the votes received.

Described is a high-assurance network gateway generator that generates and encodes network gateway code on a computer readable medium. In operation, the network gateway generator receives input artifacts, which are translated into corresponding formats as translated data. The translated data is distributed to an OS code generator, a glue code generator, and a communications code generator. The OS code generator then generates OS code based on the translated data. The communications code generator proceeds to generate deserialization and filtering code based on the translated data. Further, a glue code generator generates glue code based on the OS code and translated data. An executable network gateway code is then generated by combining the glue code, deserialization code, and filtering code. Finally, the executable network gateway code is then encoded on a computer readable medium.

Described is a system for secure multiparty computation. The system uses a secret sharing protocol to share secrets among servers of a synchronous network. An Open-Semi-Robust protocol or an Open Robust protocol is used to allow the servers to open their shares of secret data. If a server is corrupt, the Open-Robust protocol is used, otherwise, the Open-Semi-Robust protocol is used. A Deal-Semi-Robust protocol or a Deal-Robust protocol is utilized by a server to distribute its shares of secret data among the other servers. If a server is corrupt, the Deal-Robust protocol is used, otherwise, the Deal-Semi-Robust protocol is used. A Recover-Semi-Robust protocol or a Recover-Robust protocol is used to allow servers that were previously corrupted to recover their shares of secret data, such that each uncorrupted server holds correct shares of secret data. If a server is corrupt, the Recover-Robust protocol is used, otherwise, the Recover-Semi-Robust protocol is used.

Described is a system and method for monitoring and enforcing information flow security in software systems. The system maintains security tags and reference counts for objects in computer memory. When an object or a portion of an object in the computer memory is being modified, the system arbitrarily performs operations of updating a security tag for the object being modified; updating reference counts for all objects that the portion of the object in the computer memory being modified pointed to immediately prior to modification; and updating reference counts for all objects that the portion of the object in the computer memory being modified points to immediately after the modification. Subsequently, the system examines the security tags and if the examination reveals a potential information flow security violation, a corrective action is performed.

Described is a system for synthesis of cryptographic software from specification. During operation, the system generates a first level formalization code of a cryptographic protocol based on a user input protocol specification and a library of transformation rules. A second level formalization code is then generated by implementing communication protocols to the first level formalization code. A third level formalization code subsequently generated by implementing cryptographic primitives to the second level formalization code. Finally, the third level formalization code is encoded on a computer readable medium as an executable code.

Described is a system for translating security objectives to properties of software code. The system receives a software code and a description of user security objectives written in a high-level language. Using a set of inference rules, the user security objective is translated into a formal security objective. The formal security objective is adapted into a low-level property to fit a target program having software code. Finally, it is determined whether the user objective has been satisfied by analyzing the software code with respect to the low-level property.

The present invention relates to a system for detecting source code security flaws through analysis of code history. First, the system obtains a previously inferred information flow policy, the previously inferred informational flow policy being based on a previous source code revision. The system then determines changes in source code between a previous source code revision and a current source code revision. Finally, a current inferred information flow policy is generated by modifying the previously inferred information flow policy to reflect the changes in source code. If the changes in the source code do not comply with the previously inferred information flow policy, then the changes are reported to a developer.

Described is a system for a cloud control operations plane. In operation, a job is broadcast to a plurality of physical hosts, one or more of the physical hosts having a control operations plane (COP) node and a service node associated with the COP node. The COP nodes jointly create a private job assignment. A set of job assignments is redundantly distributed to individual COP nodes pursuant to the private job assignments, such that each individual COP node is only aware of its own assignment and corresponding job. The service nodes then each complete a task associated with the job and generate an output. When a set of service nodes performing a redundant job complete their task, the corresponding COP nodes jointly perform a private result checking protocol to generate a final output. The final output is then sent to the user.

A synaptic time-multiplexed (STM) neuromorphic network includes a neural fabric that includes nodes and switches to define inter-nodal connections between selected nodes of the neural fabric. The STM neuromorphic network further includes a neuromorphic controller to form subsets of a set of the inter-nodal connections representing a fully connected neural network. Each subset is formed during a different time slot of a plurality of time slots of a time multiplexing cycle of the STM neuromorphic network. In combination, the inter-nodal connection subsets implement the fully connected neural network. A method of synaptic time multiplexing a neuromorphic network includes providing the neural fabric and forming the subsets of the set of inter-nodal connections.
