Rafael Dowsley and Goichiro Hanaoka and Hideki Imai and Anderson C. A. Nascimento

Abstract: We show a method for compressing the ciphertext and reducing the computational cost of the Dolev-Dwork-Naor cryptosystem and related schemes without changing their other parameters nor reducing the original security levels.
