Note on Robust and Simple Authentication Protocol
Hung‐Yu Chien · The Computer Journal · 2005
Robust and simple authentication protocol (ROSI) is a highly efficient authentication protocol. However, its state-synchronization property makes it vulnerable to the denial of service (DOS) attack. This paper shows the DOS attack on the ROSI protocol, and proposes an improved scheme that conquers the weakness and extends its key agreement function, and improves the server's performance.
