The Low-Density Parity Check Convolutional Codes (LDPC-CC)
are considered of forward error correction codes, which combine
the power of LDPC block codes and Convolutional codes. LDPCCC
have several features such as they can be encoded with arbitrary
length by simple shift registers and can be decode by only one
decoder.
This paper presents a new type of encryption, using a matrix
asymmetric and symmetric matrix inverse matrix clear text, which
is an internal encryption.
As well as asymmetric encryption, where the ciphertext is inversely
symmetric matrix.
Decryp
tion matrix related to any asymmetric encryption keys
depends on public and private, and is applied to the coded messages
used in the current system ASCII our computers.
