  • SECURITY ANALYSIS SYSTEM AND METHOD BASED ON NEGATIVE TESTING FOR PROTOCOL IMPLEMENTATION OF LTE DEVICE
    Publication number: 20230114705
    Abstract: Disclosed are a negative testing-based security analysis system for protocol implementation of an LTE device, and a method thereof. According to an embodiment, a negative testing-based security analyzing method for protocol implementation of an LTE device performed by a computer device includes redefining a state of user equipment (UE) as a security abstraction state for a negative test and composing a test case generation rule by analyzing a specification document in redefining the state of the UE as the security abstraction state.

  • Reverse debugging of software failures
    Patent number: 10565511
    Abstract: Debugging systems are configured to resolve both memory aliasing conditions in which a write instruction is directed to an unknown destination address, and concurrency conditions in which control flow information is collected for multiple, concurrently executing threads. Recorded state values corresponding to an application's prior execution and control flow information are both obtained.
