Streszczenie
In this paper, we present a cryptosystem based on the Fourier series coefficients of a modular form attached to an elliptic curve over the rational numbers. More precisely, we show how the techniques of encryption, decryption and digital signature can be integrated in a new authenticated encryption scheme based on the $L$-series of elliptic curves cryptosystem. Finally, we show that our integrated encryption scheme is secure against known plain-text attack, much less vulnerable against key reuse and represents a non-deniable encryption scheme.
