algorithm) is been made into a synthesizable using Verilog code which can be easily implemented on to FPGA. The algorithm is composed of three main parts: cipher‚ inverse cipher and Key Expansion. Cipher converts data to an unintelligible form called plaintext. Key Expansion generates a Key schedule that is used in cipher and inverse cipher procedure. Cipher and inverse cipher are composed of special number of rounds. For the AES algorithm‚ the number of rounds to be performed during the execution of the

Data Encryption Standard In 1972‚ the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security‚ a subject then in its infancy. One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data during transmission and in storage. Prior to this NBS initiative‚ encryption had been largely the concern of military and intelligence organizations. The encryption algorithms‚ i.e.‚ the

A Novel efficient Block Based Segmentation Algorithm for Compound Image Compression ABSTRACT Compound image comprises of the combination of text‚ graphics and natural images. Compression and transmission of these compound images are the essential processes in the real time applications where segmentation plays a crucial role. Compound image transmission for real-time applications require that the compression technique should not only attains high compression ratio‚ moreover has low complexity

It was determined that based on current security guidelines and current controls in place‚ the university was still severely vulnerable from an internal aspect and all identified gaps need to be addressed and resolved.

the internet. 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 ciphertext and thus potentially has access to the original information‚ provided he is able to decipher

trustworthiness would remain the same. * Data Encryption Definition: -This is the encryption (encoding) of data for security purposes. How does it assist in securing data and maintaining its integrity? By encrypting‚ we change the original plaintext version of data into ciphertext‚ which is an unreadable format that will protect against unauthorized parties. Only those who possess the key to trigger the algorithm that will decrypt the data‚ hence making it readable‚ can access it. A higher bit
