Existing Data

<span lang="EN-US">Advanced Encryption Standard (AES) adopted by the National Institute of Standards and Technology (NIST) to replace existing Data Encryption Standard (DES), as the most widely used encryption algorithm in many security applications. Up to today, AES standard has key size variants of 128, 192, and 256-bit, where longer bit keys provide more secure ciphered text output. In the hardware perspective, bigger key size also means bigger area and small throughput. Some companies that employ ultra-high security in their systems may look for a key size bigger than 128-bit AES. In this paper, 128, 192 and 256-bit AES hardware are implemented and compared in terms of throughput and area. The target hardware used in this paper is Virtex XC5VLX50 FPGA from Xilinx. Total area and Throughput results are presented and graphically compared.</span>

At Home

AES (Advanced Encryption Standard) in May 26, 2002 became effective standard. AES algorithm research has become a hot topic at home and abroad, and the algorithm has been widely applied in the field of information security. Since the algorithm of AES key expansion part is open, so the key is between the wheel can be derived from each other, the AES algorithm designed for this security risk by generating pseudo-random number. Logistic mapping a certain length, after quantization is used as a key to improve the security of the AES algorithm.

Algorithm Parallelization

Currently, standard encryption algorithms, such as AES, are used for encryption of data in cloud. As AES algorithm is a low-speed for serial, in addition to solving its low-speed, a Parallel Algorithms is introduced. Regarding the extent of cloud network, the most important feature of the proposed algorithm is its High speed and resistivity against the attacks. The algorithm is designed and implemented in java script in cloudsim environment. The results obtained from implementation of this algorithm in cloud simulating environment, are compared and evaluated relative to the other algorithms. Similar input was fed to the proposed and other algorithms. The proposed algorithm processed the data in 82 ms which is faster than the other algorithm.

Secure Authentication

To send data over the network, devices need to authenticate themselves within the network. After authentication, the device will be able to send the data in-network. After authentication, secure communication of devices is an important task that is done with an encryption method. IoT network devices have a very small circuit with low resources and low computation power. By considering low power, less memory, low computation, and all the aspect of IoT devices, an encryption technique is needed that is suitable for this type of device. As IoT networks are heterogeneous, each device has different hardware properties, and all the devices are not on one scale. To make IoT networks secure, this paper starts with the secure authentication mechanism to verify the device that wants to be a part of the network. After that, an encryption algorithm is presented that will make the communication secure. This encryption algorithm is designed by considering all the important aspects of IoT devices (low computation, low memory, and cost).
