hmm:

p 313
g 10
x 15

h = 10^15 mod 313 = 231

but i can't continue it further as i don't know where i can get the actual message content etc.

probably because, on the wall, it says "el gamal 15"

Where did you get 313?

By the way, I believe that p = 317, not 313. But we still have to find the message....

This is a continuation of the previous clue.
10 and 304 are from the dashboard. 15 is from Elgamal. The rest is from the colours on the wall.

Good luck!

Also not sure why you meant 313 and not 307. And where on earth do the colours come into it.

The clue says that p > 304, but the algorithm says that p must be a prime number, so we take the first prime number greater than 304. But p must also satisfy the formula p = 2^k * q + 1, where q is also a prime.

My guess is that p = 317, because then you would have

317 = 2^k * q + 1 => 2^k * q = 316 an remember that q must be a prime, so you have 2^2 * 79 => q=79 and 79 is a prime number...
