On Novel Public-key Cryptosystem Using MDS Code

In this paper we will build a public-key cryptosystem using the MDS code. The advantages of this cryptosystem are that the size of the plaintext is the same as the size of ciphertext. We started with k-bit message m and ended with a k-bit ciphertext C. This may be considered economical and time saving, if compared by other systems, the length of the ciphertext is about 100 times longer than the length of the message itself
