Unfortunately, efficiency and security are opposing requirements in terms of key size, ‘small’ being good for efficiency and ‘large’ being good for security. So a suitable balance must be found. Usually, the developers of a cryptosystem recommended an appropriate key size at the time the new system was publicized; but computing environments change and attackers implement new attacks, and so key sizes must be adjusted over time. By the late 1990s work had begun on comparing cryptosystems based on current and future key sizes as functions of what were then thought to be the major contributing factors.
