One of the important applications of inverse of a non-singular square matrix is in cryptography. Cryptography is an art of communication between two people by keeping the information not known to others. It is based upon two factors, namely encryption and decryption Encryption means the process of transformation of an information (plain form) into an unreadable form (coded form).

Transcribed Image Text:One of the important applications of inverse of a non-singular square matrix is in cryptography.
Cryptography is an art of communication between two people by keeping the information not
known to others. It is based upon two factors, namely encryption and
decryption Encryption means the process of transformation of an information (plain form)
into an unreadable form (coded form). On the other hand, Decryption means
the transformation of the coded message back into original form. Encryption and decryption
require a secret technique which is known only to the sender and the recerver.
