| Abstract: | A family of binary sequences were constructed by using an elliptic curve and its twisted curves over finite fields. It was
shown that these sequences possess “good” cryptographic properties of 0–1 distribution, long period and large linear complexity.
The results indicate that such sequences provide strong potential applications in cryptography.
