Bitcoin price retests key $22.8K as metric points to 'BTC buying spree'

BTC price bulls fail to take the market higher as the week continues, but buyer interest is giving hope.

RSA algorithm with define range of d

My question is: Alice signs messages using RSA with a public key (e,N) and a private key d. Alice chooses d in the range N power 0.25 < d < N power 0.5 What is the time needed for Alice to calculate the signature S = m power d mod N? My answer is: Alice::Listen

My question is:
Alice signs messages using RSA with a public key (e,N) and a private key d. Alice chooses d in the range N power 0.25 < d < N power 0.5 What is the time needed for Alice to calculate the signature S = m power d mod N?

My answer is: Alice chooses e so that d is in the range N power 0.25 < d < N power 0.5. Since d is in the range N power 0.25 < d < N power 0.5, we have d = O(N power 0.5). Therefore, the time needed for Alice to calculate the signature S = m power d mod N is O(log d) = O(log (N power 0.5)).

But I am not sure.. can anybudy help??
