Reducing the Ciphertext Size of Dolev-Dwork-Naor like Public Key Cryptosystems
Rafael Dowsley, Goichiro Hanaoka, Hideki Imai, Anderson C. A. Nascimento · 2010
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.
