  • Garbled Circuit Generation in a Leakage-Resilient Manner
    Publication number: 20120079602
    Abstract: Methods and apparatus are provided for generating a garbled circuit for a client in a leakage-resilient manner, for use in secure function evaluation between the client and a server. The garbled circuit is generated by obtaining a token from the server, wherein said token comprises a leakage-protected area; querying the token gate-by-gate, wherein for each gate of said garbled circuit, the token interacts with the leakage-protected area to generate a garbled table for the gate; and receiving the garbled circuit from the token. The client can interact with the server to obtain garbled inputs; and then evaluate the garbled circuit on the garbled inputs to obtain a garbled output. A final output can be obtained by matching the garbled output with an output table in the garbled circuit.

  • Handling caught exceptions
    Patent number: 7877740
    Abstract: Embodiments of the invention relate to exceptions. In a Java embodiment, if the count of a program statement that causes the exception reaches a threshold, then the Java Virtual Machine (JVM) searches for the throw statement corresponding to that program statement. The JVM then identifies the catch clause corresponding to the throw statement, and depending on implementations, the JVM may replace the throw statement with the catch block or replace the throw statement with a jump to the catch block. As a result, in both situations, program execution, when being supposed to execute the throw statement, executes instructions of the catch block, and avoids execution of the throw statement that would invoke the exception handler, which improves system performance.
