Algorithm 1. Symmetric key generation at RSUx.

Input : Initial Key K_{m}

, random seed for other RSU

1. K_{a u t h}^{j}

K_{m}

2. r_{x}

= GenerateRandomSeed()
3. for all RSU in the network
4.

r_{i}

= RecievingRandomSeed from RSU i
5. StoreRandomSeed(

r_{i}

i

)
6. end

7. K_{s}^{j} = [K_{a u t h}^{j}, r_{x}]

8. for all RSU in the network
9.

K_{s}^{i} = [K_{a u t h}^{j}, r_{i}];

10. StoreSymmetricKey(

K_{s}^{i}

i

);
11. end
12.

K_{a u t h}^{j + 1} = Hash [K_{a u t h}^{j}]

;
13. if (timeout)
14. Go to step 7
