Response by MEC Clause Samples

Response by MEC. The MEC node can now easily derive the session key by SK = cm ⊕ cm ⊕ cm ⊕ d1 and verify d3 = H2(SK R1). If it is correct, the MEC node can now forward d2, d3 to the device and update its key material DIDm = cm, DKm = cm. 4 Similar as the MEC node, the device can compute SK = ci ⊕ci ⊕ci ⊕d2 and verify d3 = H2(SK R1). If correct, the device updates its identity and key material to DIDi = ci , DKi = ci .
