We propose a REinforced modified Dual-Ouroboros based on Gabidulin codes, shortly called REDOG. This is a code-based cryptosystem based on the well-known rank metric codes, Gabidulin codes. The public key sizes of REDOG are 14KB, 33KB, 63KB at the security levels of 128, 192, 256 bits respectively. There is no decoding failure in decryption. REDOG is IND-CPA. As a new result, we give the performance results of implementing REDOG including the time for Key generation, encryption, and decryption for each security level.
