Native language verification system and method
View Patent ↗The present invention includes a native language verification method for verifying native language information associated with an emulation class. Verification information associated with native language code is obtained. The native language code is referred to by an emulation language class. The legitimacy of the verification information is examined to confirm the native language is uncorrupted.
1. A computer usable storage medium having computer readable program code embodied therein for causing a computer system to implement an emulation virtual machine with native code verification comprising:
an emulation class loading module for verifying the legitimacy of emulation class information and associated native language information and loading said emulation class information if legitimate, wherein said emulation class loading module retrieves a first version of native language verification information from a particular emulation class and compares the first version to a second version that is a load time version of said native language verification information based upon information received from a native language shared library and wherein said native language verification information is a hash digest of native language code with embedded bytecode verification signature;
an emulation execution module for executing instructions and processing data included in bytecodes of loaded emulation classes; and
an emulation runtime data area module for tracking assignment of logical memory locations associated with said loaded emulation classes.
2. A computer usable storage medium of claim 1 wherein said emulation class loading module is Java compatible.
3. A computer usable storage medium of claim 1 wherein said emulation class loading module performs a native language verification method.
4. A computer usable storage medium of claim 1 wherein said hash digest is encrypted by a private key and decrypted by a corresponding public key.
