20140372769 | Automatic Protocol Selection in Mixed-Protocol Secure Computation - Secure multi-party computation may be performed utilizing mixed protocols in order to improve performance. In particular, embodiments implementing mixed protocols can reduce run time and thereby lower the cost of performing secure computation. Algorithms for optimizing selection from mixed protocols are disclosed, including an algorithm based on integer programming or an efficient heuristic algorithm for the selection problem. According to certain embodiments a selection engine is configured to receive as inputs, a function description and cost parameter(s). Based upon execution of the integer programming algorithm and the application of heuristics, the selection engine is configured to generate an output comprising a single cryptographic protocol (e.g. garbled circuit or homomorphic encryption). By employing mixed protocol selection according to embodiments, a compiler responsible for implementing secure computations can identify and select the fastest underlying mixed cryptographic protocols. | 12-18-2014 |

20150019879 | Optimal Re-Encryption Strategy for Joins in Encrypted Databases - Methods, systems, and computer-readable storage media for selecting columns for re-encryption in join operations. In some implementations, actions include determining a first column and a second column to be joined, receiving a first key corresponding to the first column and a second key corresponding to the second column, receiving a first rank associated with the first key and a second rank associated with the second key, selecting the second column for re-encryption based on the first rank and the second rank, and providing the first column, the second column, and the first key for performing a join operation, the second column being re-encrypted based on the first key. | 01-15-2015 |
20150039586 | Local Versus Remote Optimization in Encrypted Query Processing - Methods, systems, and computer-readable storage media for optimizing query processing in encrypted databases. In some implementations, actions include receiving a query that is to be used to query an encrypted database, generating a plurality of query plans based on the query, each query plan including a local query and one or more remote queries, the local query being executable at a client-side and the one or more remote queries being executable at a server-side, selecting an optimal query plan from the plurality of query plans, providing one or more remote queries of the optimal query plan to the server-side for execution, receiving one or more remote results, and processing a local query of the optimal query plan and the one or more remote results to provide a final query result. | 02-05-2015 |

20110131545 | Stepwise template integration method and system - A method, apparatus and computer program product is provided to create an integration process between a source system and target system. The integration method and system includes creating a mapping between one or more source objects and one or more target objects as part of an integration process between a respective source system and target system. The complete workflow has a sequence of activities that specifies operations on the one or more source objects and one or more target objects as between the respective source system and target system, including the mapping between one or more source objects and one or more target objects. Next, one implementation selectively includes a limited subset of operations from the sequence of activities in the complete workflow that interact with the one or more source objects and one or more target objects. These selective objects, operations and activities are identified as generally needing modification when performing an integration process. Once identified, method and systems of the present invention sequence the limited subset of operations selected from the complete workflow in a stepwise template that streamlines the integration process between the source system and target system. The subset of operations focus on mappings between and operations performed upon source objects and target objects associated with the limited subset of operations selected from the operations in the complete workflow. | 06-02-2011 |
