Statistical Analysis of ReRAM-PUF based Keyless Encryption Protocol Against Frequency Analysis Attack
This addresses security for cryptographic systems by testing a new keyless encryption concept, though it appears incremental as it focuses on analysis rather than introducing a new method.
The paper tackles the security of a keyless encryption protocol using ReRAM-PUF by analyzing its randomness and resistance to frequency attacks, finding that it provides full security against memory attacks without storing keys.
There has been a growing interest in fully integrating Physical Unclonable Function (PUF) for cryptographic primitives, or keyless encryption. Keyless primitives do not store key information during the entire encryption and decryption phase, providing full security against volatile and non-volatile memory attacks. The concept of keyless encryption using ReRAM PUF is a relatively new concept, and the security aspect of the protocol has not been tested yet. In this paper, we use statistical models to analyze the randomness of the protocol and its resistance against frequency attacks.
