1. Result of ECDLP by learning λ method on SSD device
Ellipse cryptanalysis PC uses 1 core in Intel Core i7 6700k(4Ghz).
Decryption time of ρ method is 10 hours. This decryption time is 1.0 second.
Reduce the number of iterations to 1/18000 by learning λ method on SSD device.
The multiple precision of ρ method used gmp. It of Learning λ method was self made.
The learning data is stored in the SSD device with 36 GB.
Learning data is possible on HDD but elapsed time is increased to several seconds.
Learning time of the learning λ method was spent 7 days using GPU (GTX 1080).
