Digital images that are personal and confidential are very vulnerable to wiretapping by irresponsible parties. Especially if distributed via the internet network such as on Facebook, WhatsApp and e-mail chat based applications. Images that are sent sometimes are often confidential images and must be maintained. In order to maintain the security of digital images can be done by utilizing cryptographic techniques. Cryptographic techniques can secure digital images by changing pixel values from digital images so as to produce different pixel values from the original image to be secured. This research will use AES 128 bit and Triple DES methods for encryption and decryption of digital images on client-server based applications. The results of the encryption AES algorithm will be re-encrypted with the Triple DES Algorithm so as to produce pixel values that are far different from the original pixel values. Keywords: cryptography, image, AES, Triple DES

Telemedicine is commonly used to check or diagnose patients from a long distance. Its application is often combined with sensors as needed, but for delivery, a cryptography algorithm is needed so the data sent safely, illegible, and can not be changed by unauthorized people. Besides that, the algorithm must be light, fast and use less power. In this study, a comparison of the Data Encryption Standard (DES) and Advanced Encryption Standard (AES) algorithms will be implemented in the encryption module. Data from the sensor encrypted and sent to the server. The time and power consumption by DES will be compared with AES. From this research, we can conclude that the encryption time of AES is faster than DES. The average difference speed is 33413 microseconds. Then the power consumption by AES and DES does not have any significant difference, and the addition of sensors causes additional power as well.

In recent days, increasing numbers of Internet and wireless network users have helped accelerate the need for encryption mechanisms and devices to protect user data sharing across an unsecured network. Data security, integrity, and verification may be used due to these features. In internet traffic encryption, symmetrical block chips play an essential role. Data Encryption Standard (DES) and Advanced Encryption Standard (AES) ensure privacy encryption underlying data protection standards. The DES and the AES provide information security. DES and AES have the distinction of being introduced in both hardware and applications. DES and AES hardware implementation has many advantages, such as increased performance and improved safety. This paper provides an exhaustive study of the implementation by DES and AES of field programming gate arrays (FPGAs) using both DES and AES. Since FPGAs can be defined as just one mission, computers are superior to them.

In this paper the Advanced Encryption Standard (AES) was endorsed by the National Institute of Standards and Technology in 2001. It was intended to supplant the maturing Data Encryption Standard (DES) and be valuable for a wide scope of utilizations with differing throughput, zone, control dissemination and vitality utilization necessities .Though they are very adaptable, FPGAs are regularly less effective than Application Specific Integrated Circuits (ASICs); There have been numerous AES executions that attention on acquiring high throughput or low region use, however almost no examination done in the territory of low power or vitality productive based AES; actually, it is uncommon for assessments on power dispersal to be made by any means. This postulation introduces new effective equipment usage to those propelled encryption standard (AES) calculation. Two primary commitments are introduced in this thesis, the initial you quit offering on that one will be a secondary speed 128 odds AES encrypted, and the second person is another 32 odds AES configuration. In 1st commitment An 128 odds circle unrolled sub-pipelined AES encrypted is exhibited. In this encrypted a effective blending to those encryption methodology sub-steps will be executed following relocating them. Those second commitment displays An 32 odds AES plan. In this design, the S-BOX is actualized for inward pipelining Furthermore it is imparted the middle of those principle round and the enter development units. Also, the way development unit is actualized will fill in on the fly What's more previously, parallel with the fundamental round unit. These outlines bring attained higher FPGA (Throughput/Area) effectiveness analyzing to past AES outlines.

There is a great research in the field of data security these days. Storing information digitally in the cloud and transferring it over the internet proposes risks of disclosure and unauthorized access; thus, users, organizations, and businesses are adapting new technology and methods to protect their data from breaches. In this paper, we introduce a method to provide higher security for data transferred over the internet, or information based in the cloud. The introduced method for the most part depends on the Advanced Encryption Standard (AES) algorithm, which is currently the standard for secret key encryption. A standardized version of the algorithm was used by The Federal Information Processing Standard 197 called Rijndael for the AES. The AES algorithm processes data through a combination of exclusive-OR operations (XOR), octet substitution with an S-box, row and column rotations, and MixColumn operations. The fact that the algorithm could be easily implemented and run on a regular computer in a reasonable amount of time made it highly favorable and successful. In this paper, the proposed method provides a new dimension of security to the AES algorithm by securing the key itself such that even when the key is disclosed; the text cannot be deciphered. This is done by enciphering the key using Output Feedback Block Mode Operation. This introduces a new level of security to the key in a way, in which deciphering the data requires prior knowledge of the key and the algorithm used to encipher the key for the purpose of deciphering the transferred text.

A new type of student information management system is designed to implement student information identification and management based on fingerprint identification. In order to ensure the security of data transmission, this paper proposes a data encryption method based on an improved AES algorithm. A new S-box is cleverly designed, which can significantly reduce the encryption time by improving ByteSub, ShiftRow, and MixColumn in the round transformation of the traditional AES algorithm with the process of look-up table. Experimental results show that the proposed algorithm can significantly improve the encryption time compared with the traditional AES algorithm.

In this chapter, we focus on symmetric encryption. We begin by identifying two different types of symmetric encryption algorithm, namely, stream and block ciphers. We discuss the basic idea behind a stream cipher and consider their properties and applications. We then introduce block ciphers. We focus on two extremely important and influential block cipher algorithms, the Data Encryption Standard and the Advanced Encryption Standard, discussing the history of their development as well as their basic design. We then introduce the modes of operation of a block cipher, explaining why different modes have been proposed. We examine in detail four of the most well-established modes of operation and their core properties, as well as classifying other modes of operation.

Seiring penggunaan website yang semakin luas dapat menimbulkan berbagai macam tindak kejahatan seperti pencurian, manipulasi data atau informasi penting dari suatu website oleh orang yang tidak bertanggung jawab. Dalam pemrograman web terdapat dua metode untuk mengirimkan data dari client ke server, parameter POST method dan parameter GET method. GET method request menempatkan data yang  dikirimkan  pada  URL  web  yang  dituju. hal  ini  menjadi  salah  satu kelemahan  dari  GET  method  karena  nilai variable yang dikirim menggunakan GET method dapat dilihat pada bagian URL sehingga rentan terhadap serangan SQL injection. Salah satu metode kriptografi yang dapat digunakan adalah Advanced Encryption Standard (AES). AES adalah pengganti algoritma DES (Data Encryption Standard). Hasil penelitian menunjukkan bahwa Algoritma AES dapat mengenkripsi dan mendekripsi data URL sebuah website  dengan panjang kunci yang bervariasi, yaitu 128 bit, 192 bit, dan 256 bit. sehingga  dapat  menyamarkan informasi yang terdapat pada URL, Enkripsi URL ini menghasilkan keluaran berupa URL yang tidak menampilkan variabel asli melainkan chipertext hasil enkripsi.
