Query: An Encoding-Decoding algorithm based on Padovan numbers   In this paper, we propose a new of coding/decoding algorithm using Padovan
Q-matrices. This method is based on blocked message matrices. an advantage of
this method is that the encryption of each message matrix will use a different
key and that will increase the security of the method.
