Key Concepts

Block Matrix Multiplication

Block matrix multiplication refers to the method of partitioning the message into fixed-size blocks that correspond to the dimensions of the encoding matrix. Each block is then processed via matrix multiplication, ensuring that the encoding and subsequent decoding operations are consistent and accurately recover the message.

Inverse Matrix

The inverse matrix is a key concept in decoding encoded messages. For a square matrix used in the encoding process, its inverse—if it exists—provides a method to reverse the encoding operation. Multiplying the encoded vector by the inverse matrix retrieves the original message vector.

Matrix Encoding

Matrix encoding involves representing message elements as vectors and then transforming these vectors using a matrix. This process maps the original message into an encoded form through matrix multiplication, which is a fundamental technique in linear algebra used to manipulate data mathematically.

Matrix Decoding

Matrix decoding is the process of recovering the original message from its encoded form. This is achieved by applying the inverse transformation of the encoding process, which typically involves computing the inverse of the encoding matrix and then using it to multiply the encoded vectors.
