Algorithm 3: SSO login.

Input:

S I D_{i}

S P W_{i}

.
Output:

T r u e o r F a l s e

1:
$U_{i}$ enters $S I D_{i}$ and $S P W_{i}$ .
2:
SSO server computes $A_{i}^{'} = H (S P W_{i}) \oplus H (r_{i} ∥ S I D_{i})$ .
3:
SSO server compares $A_{i}^{'}$ and $A_{i}$ .
4:
if above check holds, then output $T r u e$ , and confirm legitimacy of $U_{i}$ .
5:
otherwise, output $F a l s e$ , and terminate the login.
