Critical Analysis of New Protocols on Lightweight Authentication.

The paper critically analyzes three recently proposed lightweight authentication protocols from three categories (i.e. CAN, PUF and RFID), and points out a few delicate issues in the three protocols, particularly: 1) LeiA lightweight authentication protocol for CAN might be vulnerable to key-recovery-attacks; 2) The lockdown technique to prevent machine learning on PUFs for lightweight authentication cannot prevent from flooding attacks; and 3) SLAP succinct and lightweight authentication protocol for low-cost RFID system, but lacks scalability and retrieval capability for mass tags.
