Some of the brightest minds in the field, gathered here for the RSA Conference, said that there are some worrying cracks showing in the cryptosystems that secure electronic communications. Whit Diffie, Ron Rivest and Adi Shamir all discussed the many problems that are facing users and implementers of cryptsystems. Diffie suggested a possible solution: publishing a hash of every public key as it s generated. Rivest suggested that instead of focusing all of our energy on new and different ways to keep those keys safe, researchers should be looking for ways to recover when those keys are stolen.
