Improved Design Of Des Algorithm Based On Symmetric Encryption In this paper, a cryptographic algorithm design called tiny encryption algorithm (tea) is proposed in order to minimize the memory footprint and maximize the speed. In this paper, architecture and the fpga implementation of the tiny encryption algorithm (tea) and a key generation using linear feedback are proposed. the system works for the both encryption and decryption processes and has been optimized for low hardware resources and for high– speed operation.

Tiny Encryption Algorithm Codeproject The tiny encryption algorithm (tea) was designed by wheeler and needham to be indeed “tiny” (small and simple), yet fast and cryptographically strong. in my research and experiments, i sought to gain first hand experience to assess its relative simplicity, performance, and effectiveness. The tiny encryption algorithm is one of the fastest and most efficient cryptographic algorithms in existence. it was developed by david wheeler and roger needham at the computer laboratory of cambridge university. The first paper shows design of a short encryption algorithm which gives security with simplicity using a large number of rounds based upon feistel iterations. this algorithm is called tiny encryption algorithm or tea. The tiny encryption algorithm (tea) is a suitable lightweight cryptographic algorithm used in medium security systems such as rfid systems. the tea is a fiestel structure used to satisfy the confusion and the diffusion properties to hide the statistical characteristics of the plaintext.

Called advanced encryption standard (aes). in this paper, the tiny advanced encryption standard (taes) algorithm has been proposed with two scenarios to improve the aes algorithm's encryption sp. This paper describes vlsi implementation of idea encryption algorithm using verilog hdl. in this implementation, modulus multiplier is optimized and the temporal parallelism available. In this paper, a cryptographic algorithm design called tiny encryption algorithm (tea) is proposed in order to minimize the memory footprint and maximize the speed. the design was targeted for embedded and mobile systems which concern more on speed and space. The main objective of this paper is to propose a lightweight and fast encryption algorithm based on the aes algorithm called tiny aes (taes) algorithm. as opposed to the original aes, this proposed algorithm tries to implement text and image encryption rapidly.
