This study focuses on semi-quantum private comparison (SQPC) protocols, where participants with limited quantum capabilities compare information the help of a third party (TP). Yan et al. introduced an SQPC protocol in 2021, but Li later found it vulnerable to double controlled NOT (CNOT) operation attacks and proposed improvements. However, this identifies different vulnerability al.’s — reflecting attack that allows leakage. Bob can intercept reflect states, avoiding detection then use Alice’s measurement outcomes pre-shared key access her confidential information. The also proposes enhanced method secure protocol.
