WebIn the context of new threats to Public Key Cryptography arising from a growing computational power both in classic and in quantum worlds, we present a new group law defined on a subset of the projective plane F P 2 over an arbitrary field F , which lends itself to applications in Public Key Cryptography and turns out to be more efficient in terms of … Webord(2 37) = 11 8 = 88 = 89 1. Hence, 74 is a primitive root modulo 89. Question 6. Find a primitive root modulo 61. Solution: Let us check that 2 is a primitive root modulo 61. Thus, we need to check that the order of 2 is exactly 60. Notice that the order of 2 must be a divisor of 60 = 4 35, so the possible orders are: 1;2;3;4;5;6;10;12;15;20 ... how many nobel prizes marie curie won
