New Technique for Key Exchange Protocol
proposed scheme
A New Technique for Diffie-Hillman Key Exchange Protocol Security using Random Image Generation
to improve the security of the Diffie–Hellman protocol
4 Stage
Random image generation
Random key generation from step1
Key Exchange method
Apply the RSA algorithm
Experimental Result
The keys generated from an image is more secure from Pseudo-Random numbers
The structure of this method is more straightforward
It provides the ability to exchange the keys without much time needed
Image size increased.
the security was increased with image size.
type of cryptographic algorithms
symmetric algorithms
asymmetric algorithms
Diffie-Hellman protocol
utilizes 2 public-key cryptosystem
the first key is a public key to encrypt data
the second key is the private key to decrypt data
vulnerabilities
Man-in-the-Middle
discrete logarithm
RSA algorithm
algorithm for implementing the Diffie-hillman key exchange protocol
Public-key encryption
Digital Signature
Encryption
B Obtains the public key (n, e)
Acts the message (plaintext) as a positive integer M.
Calculates the cypher-text by applying 〖C=M〗^e mod n
Sends the message (cypher-text) from A to B.
Decryption
After receiving the encrypted message by recipient “B”.
After the recipient "B” receives the encrypted message sent from the sender "A", B must take some steps to read this message
Computing M=C^d mod n, on cipher text to extract the plain text
Extracting the plaintext by converting the result M from the integers to letters M
