In a DHKE scheme with the a prime p = 467. an element g = 4. The element 4 has order 233 and generates thus a subgroup with 233 elements. after Computing the common key for A. a=400, b=134 B. a=167, b=134 the session keys are identical = 161
Can someone tell me the answer as to why the key is the same for both schemes given different values for a ?
