Using a shared instance is surely faster. However, the API specified 
that the most preferred SecureRandom impl will be used. To ensure this 
for all scenarios, creating default SecureRandom obj will provide 
correct result but shared instance may not. Apps can call other init 
functions which takes SecureRandom objects to avoid this default 
SecureRandom obj creation if needed.
