An approach for designing fast public key encryption systems using white-box cryptography techniques

I present an approach for designing fast public key encryption cryptosystems using random primitives, white-box cryptography techniques and obfuscated error permutation. An encryption speed of such systems allows to use them for “on-the-fly” public key encryption and makes them useful for real-time communications. A small error size allows to use this approach for designing digital signature schemes and systems of Digital Rights Management (DRM). An underlying hard problem is the problem of finding low weight codewords which is known to be NP-hard.
