Considering digital image features with high volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the

com Abstract—The embedded based applications need sensitive data transfer between different nodes. In order to increase the speed and to reduce the hardware complexity‚ this proposed system focuses on the light weight security algorithm Tiny Encryption Algorithm TEA which can be implemented in microcontroller to adapt with many real time constraints such as memory‚ data loss and low cost. The additive feature of this proposed system is that it uses Key Generation Unit (KGU) to produce the

Technology‚ when they decided to create the RSA cryptosystem together. This algorithm was created in 1977. In later years‚ the three students started the company “RSA Security LLC” in 1982. RSA Cryptosystem’s main aim was to encrypt‚ hide‚ private messages between the sender and recipient‚ so that only them could unlock and discover the message while it’s being sent through an unsecure channel. The process of encryption and decryption was and still is successful. Due to the fact that it utilizes

There are three steps involved in transferring information securely from person A to person B over an insecure network. These are encryption of the original information‚ called the plaintext‚ transfer of the encrypted message‚ or ciphertext‚ and decryption of the ciphertext back into plaintext. Since the transfer of the ciphertext is over an insecure network‚ any spy has access to the
