In the same manner, the AuC executes the following functions to authenticate the NFC POS: (4) using all values of IDPnew or IDPold, the AuC performs the H (IDPnew/IDPold [parallel] R1) function to compute the hash value (HIDP
) that is equal to the hash value (HIDP
) received from NFC POS; if HIDP
is satisfied based on the IDPnew, the corresponding KPnew is retrieved and the flag value F2=1, else if the IDP = IDPold then KPold is retrieved and F2=0, else the authentication session is terminated by the AuC; (5) computes R3 value where R3 = IDP [symmetry] M4; (6) executes the XM3 = (KMnew/KMnew [parallel] R1 [parallel] R3) function to compute expected hash value XM3; if XM3 = M3, the NFC POS is verified, else the AuC terminates the session.
PPE cases with HIDP serotypes were older than those with LIDP serotypes (median ages 56 and 24 months, respectively; p = 0.0001) (Table 5).
