This course is an introduction to elliptic curves over finite fields and their arithmetic properties that relevant in their cryptographic applications. The aspects of computational complexity are analyzed in some details as they are the main choice criterion of encryption schemes.
The presentation is set in the historical perspective of the development of elliptic functions which were discovered by an Italian mathematician and brilliantly extended by Euler.
