“…For comparison with AES, we will use one of the more recent results from [UMHA16] where an area-speed optimized AES-128 (10 rounds) on NanGate 15nm technology runs with the speed 71.19 Gbps and has the area 17232 GE. This means that having the same design, AES-256 (14 rounds) would run with the speed of 50.85 Gbps.…”

In this paper we are proposing a new member in the SNOW family of stream ciphers, called SNOW-V. The motivation is to meet an industry demand of very high speed encryption in a virtualized environment, something that can be expected to be relevant in a future 5G mobile communication system. We are revising the SNOW 3G architecture to be competitive in such a pure software environment, making use of both existing acceleration instructions for the AES encryption round function as well as the ability of modern CPUs to handle large vectors of integers (e.g. SIMD instructions). We have kept the general design from SNOW 3G, in terms of linear feedback shift register (LFSR) and Finite State Machine (FSM), but both entities are updated to better align with vectorized implementations. The LFSR part is new and operates 8 times the speed of the FSM. We have furthermore increased the total state size by using 128-bit registers in the FSM, we use the full AES encryption round function in the FSM update, and, finally, the initialization phase includes a masking with key bits at its end. The result is an algorithm generally much faster than AES-256 and with expected security not worse than AES-256.

“…Willing to consider a realistic AES implementation for exhaustive key search purposes, we refer to [38], where the authors survey the state of the art of Application-Specific Integrated Circuit (ASIC) AES implementations, employing the throughput per Gate Equivalent (GE) as their figure of merit. The most performing AES implementations are the ones proposed in [38], and require around 16ki GEs. We thus deem reasonable to estimate the computational complexity of an execution of AES as 16ki binary operations.…”

We consider the QC-LDPC code-based cryptosystems named LEDAcrypt, which are under consideration by NIST for the second round of the post-quantum cryptography standardization initiative. LEDAcrypt is the result of the merger of the key encapsulation mechanism LEDAkem and the public-key cryptosystem LEDApkc, which were submitted to the first round of the same competition. We provide a detailed quantification of the quantum and classical computational efforts needed to foil the cryptographic guarantees of these systems. To this end, we take into account the best known attacks that can be mounted against them employing both classical and quantum computers, and compare their computational complexities with the ones required to break AES, coherently with the NIST requirements. Assuming the original LEDAkem and LEDApkc parameters as a reference, we introduce an algorithmic optimization procedure to design new sets of parameters for LEDAcrypt. These novel sets match the security levels in the NIST call and make the C99 reference implementation of the systems exhibit significantly improved figures of merit, in terms of both running times and key sizes. As a further contribution, we develop a theoretical characterization of the decryption failure rate (DFR) of LEDAcrypt cryptosystems, which allows new instances of the systems with guaranteed low DFR to be designed. Such a characterization is crucial to withstand recent attacks exploiting the reactions of the legitimate recipient upon decrypting multiple ciphertexts with the same private key, and consequentially it is able to ensure a lifecycle of the corresponding key pairs which can be sufficient for the wide majority of practical purposes.

“…The system that created is based on AES, which is it very best performing algorithm in ciphering and deciphering since it doesn't need complex mathematical formula [3,10]. And it has flexibility in use because of it can used in ciphering message or images [10,11]. Also, the AES is chosen based on preforming of the algorithm.…”

The increase number of eavesdropping or cracker to attack the information and hack the privacy of people. So, the essential issue is making system capable of ciphering information with rapid speed. Due to the advance in computer eavesdropping and cracker that made them to analysis the way of ciphering in rapid speed way. The development in the computer especially in the rapid processer in the last decade create the breaching of any system is a matter of time. Owing to most of breaching ways are based on analysis of system that requireы to be breached and to try brute force on that system to crack it. However, the lacking of influential processers that are capable of breaching system since earlier processors are limit to number of instructions. It can be done in second, which was not sufficient trying to break the system using brute force. In addition, the time required is far away from getting valuable messages in the time that needed. So, the research gives the focus on performing rapid system for ciphering the information rapidly and changing the ciphering every few milliseconds. The changing of ciphering in every millisecond helps system form preventing the eavesdropping and cracker from imposing brute force on the system and hacking the messages and images. The system that created is based on Advanced Encryption Standard (AES), which is it very best performing algorithm in ciphering and deciphering since it doesn’t need complex mathematical formula. The research is about designing system that capable of performing AES by using high processer designed on Field programmable gate Area (FPGA). The ciphering of AES using FPGA helps minimize the time required to cipher the information. Also, the research will focus on ciphering and deciphering of images by AES using FPGA
