The Internet of Things (IoT) could also be a network of connected vehicles, physical devices, software, and electronic
things that facilitates data exchange. The aim of IoT is to provide the IT-infrastructure for the secure and reliable exchange of
“things.” safety of this knowledge could be a difficult task; but, security challenges will be lessened with cryptography and
Steganography techniques. These techniques square measure crucial once addressing user authentication and knowledge
privacy. Within the planned work, the elliptic Variety Galois cryptography protocol is introduced and mentioned. During this
protocol, a cryptography technique is employed to encode confidential knowledge that came from totally different medical
sources. Next, a Matrix XOR coding Steganography technique is employed to embed the encrypted knowledge into an occasional
complexes image. The planned work additionally uses associate optimization algorithmic rule is a known as adaptation Firefly to
optimize the option of canopy blocks
