An asymptotic lower bound such as exponential-hardness is generally thought to imply that a problem is "inherently difficult". Encryption that is "inherently difficult" to break is thought to be secure. However, an asymptotic lower bound does not rule out the possibility that a huge but finite class of problem instances are easy (eg. all instances with size less than 101000). Is there any reason to think that cryptography being based on asymptotic lower bounds would confer any particular level of...
