Problem 10. You and Bob are setting up an elliptic curve Diffie-Hellman key exchange. You agree to use the curve y2 = r + 12.c + 19, the prime p=79383325070544946995240482785923708381947905804121, and the point P E E(F) given by P= (64754076003824597023219840569237094200675975619532, 73590601675094550988188459863671053770441890824788) You choose the secret integer nA = 67631687813648832315992907461512932902396663054983. You receive the following point from Bob: QB = (65691494785542945491518826567647404014545612422966, 68235886540588467328450345384577891970928526780936) Compute the shared secret. Problem 10.
