ECC is advanced Cryptography scheme which is advanced and take less size of keys to implement security and also provide methods to implement customer authentication very well. ATM is Automated Teller Machine with which ECC is combined to make it much secure and reliable. ECDSA algorithm is used to generate signatures for authentication. Elliptic Curves provide much secure keys which is the strongest part of this simulation work.
