# Example of Attack

## Decryption input data

• The first 6 are in the order of coefficients p, r, a, b, Qx, Qy.
• Base point: Q=(Qx.Qy), Solve points : R=(Rx,Ry)
• Line 7: Number of factors in r (8 in the example).
• Line 8: Factor of r (blank between factors).
• Line 9: Number of decoding points (100 in the example).
• After: Arrange Rx and Ry in units of two lines.

## Decrypt in 90 seconds

• Each 100 ECC-256 decryption results.
• Rho-x is the decryption result for the in-x input (x=1,2,3,4,5).
• 100 cracks take about 9000 seconds, one break takes 90 seconds on average.
• Show details of decryption (decryption information for the factor of r).
• The program is C. The python program is about 20 times slower.

## Decrypt in 0.01 seconds

• Each 100 ECC-256 decryption results.
• Learn-x is the decryption result for the in-x input (x=1,2,3,4,5).
• 100 cracks take 1.0 seconds, one break takes 0.01 seconds on average.
• Details of decryption are omitted.
• table=x is the conversion time of each factor.
• total=x is the total decoding time.
