Identity-Based Encryption with Equality Test Supporting Accountable Authorization in Cloud Computing .

Figures of the Article

System model of IBEET in cloud computing. $d_{ID}$ : the private key of the authorizer $U_1$ with $ID$ . $td_{ID}$ : the trapdoor of the authorizer $U_1$ with $ID$ .
System model of IBEET-AA in cloud computing. $ID_t$ : the identity of the tester. $td_{ID, \ ID_t}$ : the trapdoor of the authorizer $U_1$ with $ID$ for the tester with $ID_t$ . $td_{ID, \ *}, td_{ID, \ *}'$ : the to-be-traced trapdoor related to the authorizer $U_1$ with $ID$ and an unknown tester with identity $*$ .
IND-ID-ATK game. $M_0^*,\, M_1^*$ : two messages chosen by the adversary $\mathcal{A}$ . $\delta$ : information known by the adversary $\mathcal{A}$ when it accesses the $\mathcal{O}_1$ oracle. $b$ : a random bit chosen from $\{0,\, 1\}$ . $b'$ : the bit output by the adversary $\mathcal{A}$ .
OW-ID-ATK game. $\delta$ : information known by the adversary $\mathcal{A}$ when it accesses the $\mathcal{O}$ oracle. $M^*$ : the challenge message chosen from the message space $\mathcal{M}$ . $M'$ : the message output by the adversary $\mathcal{A}$ .
