Digital Signatures: DSA with Medium Fields

[lange-01] - 0 users already solved this challenge.
 
 
 

This challenge concerns the Discrete Logarithm Problem (DLP) in a "medium" field.
For powers of very small primes and for large prime fields the function-field sieve and the number-field sieve are highly optimized; for intermediate fields algorithms with the same asymptotic behavior exist but the actual running times are slower. Are you able to solve the DLP in such a field anyway?
