The paper investigates the vulnerability of the recently published first semiquantum identity authentication protocol (Quantum Information Processing 18: 197, 2019) to the introduced herein multisession attacks. The impersonation of the legitimate parties by a proper combination of phishing techniques is demonstrated. The improved version that closes the identified loophole is also introduced}, type={Article}, title={Semiquantum authentication of users resistant to multisession attacks}, URL={http://journals.pan.pl/Content/119991/PDF/28_02101_Bpast.No.69(4)_27.08.21_druk.pdf}, doi={10.24425/bpasts.2021.137729}, keywords={quantum cryptography, quantum identity authentication, semi-quantum communication}, }
