- 1. DESIGN AND IMPLEMENTATION OF DATA SECURITY USING ADVANCED ENCRYPTION STANDARD(AES)
- 2. ABSTRACT The daily demands of 60 percent of the world's population include the internet, which is a need in modern living. Data security and privacy are issues when using the internet because hackers can use this data. Therefore, taking this into consideration, we proposed the advance custom configurable algorithm for AES in this article. This is accomplished by adding an additional layer of protection to each letter of a message so that hackers cannot encrypt it. We are adding a new layer of encryption that is already specified by the algorithm, changing the keys for each letter and removing the vulnerability to frequent attacks. The already more secure AES algorithm is protected by this new layer. Digital encryption plays a crucial role in today's digital environment in protecting electronic data transfers. This information consists of documents related to finances and the law, to health, to automatic and online banking etc. The Advanced Encryption Standard (AES) for electrical data encryption can be utilized to meet these requirements. Although no significant AES attacks have been identified to far, Keywords:- AES(Advanced Encryption Standard
- 3. INTRODUCTION Advanced Encryption Standard, also known as AES, is widely used symmetric encryption technique. It is mostly utilized to encrypt and safeguard electronic data. Because it is faster and more effective than DES (Data encryption standard), it was used to replace DES. AES is a block cipher, and it comprises of three different block ciphers that are used to provide data encryption. Key sizes range from 128 to 256 bits. Data is encrypted in chunks of 128 bits. Thus, from 128 bits of input, it produces 128 bits of encrypted cipher text as output. The substitution-permutation network principle, which underlies AES's functioning, involves a series of connected processes that replace and shuffle the incoming data. How the cipher works : Instead than operating on bits of data, AES operates on data in bytes. The encryption examines 128 bits (or 16 bytes) of the incoming data at a time since each block is 128 bits in size. According to the key length, the number of rounds will vary as follows: • 10 rounds with a 128-bit key • 12 cycles for a 192-bit key • 14 cycles for a 256-bit key
- 4. PROPOSED SYSTEM ENCRYPTION :The sender, who wishes to send a text message to another user known as the recipient, initiates the application. The Caesar cypher is used to encrypt the plaintext, which is entered into a textbox and then converted to an intermediate ciphertext when the "encrypt" button is pressed. The last letter of the plaintext is used as the key in this encryption, and depending on whether the string is odd or even in length, it is inserted at a specific index in the ciphertext. Decryption: Using a customised Caesar Cipher decryption configuration and the AES approach in reverse, the user will be able to transform the ciphertext into plaintext in this case. On the receiver's end, this is done in the application. This is accomplished by using the JAVA programming language and creating the AES algorithm's code. The plaintext is converted to ciphertext and then stored in the database. The same process is used for decryption as well, but in reverse. The ciphertext is taken out of the database and made plaintext again. The military and several top-secret government intelligence agencies will be the main users of this application. Basically, this concept can be used by any company that wants to exchange messages with high security.
- 6. PIPELINED ARCHITECTURE • Three architectural optimization approaches can be used to speed up the AES algorithm in non-feedback modes by duplicating hardware for implementing each round, which is also called round unit. • These architectures are based on pipelining, subpipelining and loop- unrolling. The pipelined architecture is realized by inserting rows of registers between each round unit. • Similar to the pipelining, subpipelining also inserts rows of registers among combinational logic, but registers are inserted both between and inside each round unit. • In pipelining and subpipelining, multiple blocks of data are processed simultaneously. Comparatively, loop unrolled or unfolded architectures can process only one block of data at a time, but multiple rounds are processed in each clock cycle. • Among these architectural optimization approaches, subpipelining can achieve maximum speedup and optimum speed/area ratio in non- feedback modes.

- 10. LITERATURE SURVEY • NIST (National Institute of Standards and Technology) created AES in 1997. It was created to take the place of DES, which was slow and open to many attacks. In order to fix DES's flaws, a new encryption algorithm was developed. AES was subsequently released on November 26, 2001. • N Sivasankari et al. (2017) report that both encryption and decryption have been actualized into a single chip (FPGA-XC5VLX50T), and that they perform with minimal resource utilisation and a high throughput of 38.65Gbps in their paper "Implementation of Area Efficient 128-bit Based AES Algorithm in FPGA."
