Arjen Lenstra, vice president at Citibank's Corporate Technology Office in New York and a participant in the project, noted "The amount of computation we did is more than what is needed to crack a secret-key system like DES and enough to crack a public-key system like RSA of at least 600 bits".

François Morain

Job Titles:
  • Professor of Computer Science at École Polytechnique
François Morain, Professor of Computer Science at École Polytechnique, explained: "To use a curve for ECC one first has to calculate the number of points on it, which is quite a difficult task. To improve security one should use arbitrary curves picked at random and change them frequently, but currently most cryptosystems use fixed curves chosen to have particular properties which make it easy to compute the cardinality. These very properties could one day endanger them, as happened with super-singular curves. There have been dramatic improvements in point-counting algorithms and good implementations are now becoming available. Recent progress should soon undermine any remaining argument in favour of special curves".
