Non-malleable obfuscator for sparse functions

摘要

Described is a system for obfuscating a computer program. Sensitive data of an unprotected computer program is received as input. A random oracle is used to algebraically hide a set of polynomial-size point functions representing the sensitive data. The system outputs a set of obfuscated instructions internally hiding the sensitive data. The set of obfuscated instructions are used to transform the unprotected computer program into a protected, obfuscated computer program that is accepting of the set of polynomial-size point functions. The obfuscated computer program is written to a non-volatile computer-readable medium.
