Abstract: Security has become an increasingly important feature with the growth of electronic communication
which calls for more advanced ways to encrypt the raw data[1]AES-128 is going to be implemented as the
encryption algorithm as there are 3 types of AES (AES-128,AES-192,AES-256) but why AES? Because AES is
famous for its ciphering strength and its strong defense against any attack for example the brute force attack.
Using Brute force attack on AES-128 (smallest key length) is unlikely to be practical in the foreseeable future
[3]. According to NIST, "Assuming that one could build a machine that could recover a DES key (DES is an old
encryption algorithm which no one uses now in modern days) in a second (i.e.,try 2^55 keys per second), then it
would take that machine approximately 149 thousand-billion (149 trillion) years to crack a 128-bit AES key".
In this paper AES-128 will be implemented on a microcontroller circuit to give it further security and more
speed in both the encryption and decryption of the files.
Keywords: AES, Cryptography, DES, NIST, Rijndael, Serpent.

Internet Protocol Security (IP Security) is a security protocol that serves to secure information in the event of an exchange on the internet. It happens if there is a connection between private IP and public IP. This protocol will exchange packets on the IP layer safely. It provides two types of encryption options, transport, and tunnel. Transport mode will encrypt the data section without changing the packet header. The algorithm used to encrypt data is a symmetric cryptography algorithm. This protocol authenticates and encrypts every packet from a data transmission session. Also, it can generate keys between the sender and the recipient at the first time it is activated and can negotiate the cryptographic keys that will be used during the session. IP Security is an end-to-end cryptosystem that works at the internet layer of the Internet Protocol Suite. The protocol serves to protect the data flow in host-to-host, network-to-network, and network-to-host as well.

A novel approach to information security using safe exchange of encrypted dat...eSAT Journals
Abstract In this modern era, with the vast improvement in the field of internet, security is a major issue at hand. A lot of crimes, or to say, hacking is prevalent. This system "Safe Exchange of Encrypted Data (SEED)" handles sharing secret data between the sender and receiver in a cryptic manner by providing a new approach to symmetric encryption with ensured confidentiality, authenticity, integrity and availability of a secure communication, and protection against Man-in-the-Middle attacks even without a Public Key Infrastructure (PKI) or endpoint certificates, in the unprotected network space. This system makes use of an efficient concept called 'ephemeral shared session key', which being a combination of public and private keys can only be generated at both ends and negates the need of having to transmit a symmetric key between the users. The text data is encrypted using a new symmetric key algorithm known as “Xenacrypt” which is more secure than any other existing symmetric key algorithms. This system provides integrity through an efficient algorithm which we have implemented to indicate data thefts by any malicious attacks or threats. Application of this crypto-system will have a huge impact in the future of transmitting secure data especially in the field of business transaction and military operations.

A comparitive analysis of wireless security protocols (wep and wpa2)pijans
Wireless local area networks (WLANs) are become popular as they are fast, cost effective, flexible and easy
to use. There are some challenges of security and for IT administrators the choice of security protocol is a
critical issue. The main motive of this paper is to make the non-specialist reader knowledgeable about
threats in the wireless security and make them aware about the disadvantages of wireless security
protocols. WEP (Wired Equivalent privacy), WPA (Wi-Fi Protected Access) and RSN (Robust Security
Network) security protocols are defined and examined here. This security protocols are compared with the
common.
This paper is a comparative analysis of WEP, WPA and WPA2. We have tried to perform and check
authentication of all 3 protocols by implying the legendary attack vector scripts i.e. Air crack set of tools.
The test was conducted on Back Track operating system which is considered as dedicated pentesting
operating system. In the test result, we found out that WEP is the weakest, to which WPA was a temporary
solution and WPA2 is a very solid and long term solution.
This paper is a mixture of wireless security weaknesses and counter measures to the problems faced until
recently. After reading this paper the non specialist reader will have complete review and awareness about
the wireless security and vulnerabilities involved with it.
While computer systems today have some of the best security systems ever, they are more vulnerable than ever before.
This vulnerability stems from the world-wide access to computer systems via the Internet.
Computer and network security comes in many forms, including encryption algorithms, access to facilities, digital signatures, and using fingerprints and face scans as passwords.
DATA SECURITY IN MOBILE DEVICES BY GEO LOCKINGIJNSA Journal
In this paper we present a way of hiding the data in mobile devices from being compromised. We use two level data hiding technique, where in its first level data is encrypted and stored in special records and the second level being a typical password protection scheme. The second level is for secure access of information from the device. In the first level, encryption of the data is done using the location coordinates as key. Location Coordinates are rounded up figures of longitude and latitude information. In the second phase the password entry differs from conventional schemes. Here we have used the patterns of traditional Rangoli for specifying the password and gaining access, thus minimising the chances of data leak in hostile situations. The proposed structure would be a better trade off in comparison with the previous models which use Bio Metric authentication – a relatively costly way of
authentication.
Time Performance Analysis of RSA and Elgamal Public Key Cryptosystemsijtsrd
Computer and network security system are needed to protect data during their transmissions and to guarantee that data are authentic. Cryptography is useful not only for proving data to be secure but also for ensuring that data have not altered. So, it is needed to implement the public key cryptosystem in computer and network security system. In cryptography, symmetric key cryptosystems are faster than public key asymmetric cryptosystems. But public key cryptosystems are more secure than symmetric key cryptosystems and widely used in computer and network security system. This describes the comparison of RSA Rivest, Shame, Adelman public key cryptosystem and ElGamal public key cryptosystem. RSA public key cryptosystem is faster than ElGamal in encryption and decryption. This paper also describes the encryption decryption time comparison of RSA and ElGamal.

Cryptography technology is a security technique used to change plain text to another shape of data or to
symbols, which is known as the cipher text. Cryptography aims to keep the data secure during its journey
through public networks. Currently, there are many proposed algorithms that provide this service
especially for sensitive data or very important conversations either through mobile or video conferences. In
this paper, an inventive security symmetric algorithm is implemented and evaluated, and its performance is
compared to the AES. The algorithm has four different rounds for each quarter of the key container table,
and each of them serves to shift the table. The algorithm uses the XOR operation, which, being lightweight
and cheap, is very appropriate for use with Real Time Applications. The result shows that the suggested
algorithm spends less time than AES although it has 16 rounds and the numbers used to mix up the table
are big.

A dynamic data encryption method based on addressing the data importance on ...IJECEIAES
The rapid growth of internet of things (IoT) in multiple areas brings research challenges closely linked to the nature of IoT technology. Therefore, there has been a need to secure the collected data from IoT sensors in an efficient and dynamic way taking into consideration the nature of collected data due to its importance. So, in this paper, a dynamic algorithm has been developed to distinguish the importance of data collected and apply the suitable security approach for each type of data collected. This was done by using hybrid system that combines block cipher and stream cipher systems. After data classification using machine learning classifiers the less important data are encrypted using stream cipher (SC) that use rivest cipher 4 algorithm, and more important data encrypted using block cipher (BC) that use advanced encryption standard algorithm. By applying a performance evaluation using simulation, the proposed method guarantees that it encrypts the data with less central processing unit (CPU) time with improvement in the security over the data by using the proposed hybrid system.
Chaotic Rivest-Shamir-Adlerman Algorithm with Data Encryption Standard Schedu...journalBEEI
Cryptography, which involves the use of a cipher, describes a process of encrypting information so that its meaning is hidden and thus, secured from those who do not know how to decrypt the information. Cryptography algorithms come with the various types including the symmetric key algorithms and asymmetric key algorithms. In this paper, the authors applied the most commonly used algorithm, which is the RSA algorithm together with the Chaos system and the basic security device employed in the worldwide organizations which is the Data Encryption Standard (DES) with the objective to make a hybrid data encryption. The advantage of a chaos system which is its unpredictability through the use of multiple keys and the secrecy of the RSA which is based on integer factorization’s difficulty is combined for a more secure and reliable cryptography. The key generation was made more secure by applying the DES schedule to change the keys for encryption. The main strength of the proposed system is the chaotic variable key generator that chages the value of encrypted message whenever a different number of key is used. Using the provided examples the strength of security of the proposed system was tested and demonstrated.
Encryption Data Measurement and Data Security of Hybrid AES and RSA Algorithmijtsrd
Transferring the secure data becomes vital for the important data of every days life. The system is a secure data transferring, combining the two techniques, Advance Encryption Standard AES and RSA. The data file is encrypted by using AES with the randomly generated key. This key is also encrypted by RSA using the receivers public key. The encrypted data file and encrypted key file are combined to form an output file to send to the receiver. The file at the receivers side is separated into two files, the encrypted data file and encrypted key file. The encrypted key file is decrypted by RSA method using the receivers private key. The AES key is acquired, the encrypted data file is then decrypted by AES method using the acquired AES key. The system includes file transferring process based on the Java socket technology.

Securing sensitive and important information from intruders is a tedious task in the 21st century. In order to protect information different ciphering techniques has been used. Quantum Cryptography has taken a new path in the field of crypto systems where all the presently used crypto systems are classified as classical cryptography systems. Classical cryptography systems use mathematical formulas where quantum cryptography uses the principles of photon polarization and heisenberg uncertainty principle. As the south
asian region is developing rapidly in almost all the sectorsthe need of securing information has become a difficult task. Therefore, the need of starting extensive research on quantum cryptography for the south asian region to safeguard information from intruders has been the purpose of this study. Comparative study of the growth of the telecommunication sector in the south asian region and how quantum
cryptography could assist in securing information has been discussedas results.In the end, details of the need to research on quantum cryptography in the south asian region to overcome future predicted cyber threats are also discussed.
Improved Image Encryption for Real-Time Application over Wireless Communicati...ijeei-iaes
Advances in communication networks have enabled organization to send confidential data such as digital images over wireless networks. However, the broadcast nature of wireless communication channel has made it vulnerable to attack from eavesdroppers. We have developed a hybrid cryptography technique, and we present its application to digital images as a means of improving the security of digital image for transmission over wireless communication networks. The hybrid technique uses a combination of a symmetric (Data Encryption Standard) and asymmetric (Rivest Shamir Adleman) cryptographic algorithms to secure data to be transmitted between different nodes of a wireless network. Three different image samples of type jpeg, png and jpg were tested using this technique. The results obtained showed that the hybrid system encrypt the images with minimal simulation time, and high throughput. More importantly, there is no relation or information between the original images and their encrypted form, according to Shannon’s definition of perfect security, thereby making the system much more secure.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract: Security has become an increasingly important feature with the growth of electronic communication
which calls for more advanced ways to encrypt the raw data[1]AES-128 is going to be implemented as the
encryption algorithm as there are 3 types of AES (AES-128,AES-192,AES-256) but why AES? Because AES is
famous for its ciphering strength and its strong defense against any attack for example the brute force attack.
Using Brute force attack on AES-128 (smallest key length) is unlikely to be practical in the foreseeable future
[3]. According to NIST, "Assuming that one could build a machine that could recover a DES key (DES is an old
encryption algorithm which no one uses now in modern days) in a second (i.e.,try 2^55 keys per second), then it
would take that machine approximately 149 thousand-billion (149 trillion) years to crack a 128-bit AES key".
In this paper AES-128 will be implemented on a microcontroller circuit to give it further security and more
speed in both the encryption and decryption of the files.
Keywords: AES, Cryptography, DES, NIST, Rijndael, Serpent.
I. Introduction:
Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until
recent decades, it has been the story of what might be called classic cryptography — that is, of methods
of encryption that use pen and paper, or perhaps simple mechanical aids. In the early 20th century, the invention
of complex mechanical and electromechanical machines, such as the Enigma rotor machine, provided more
sophisticated and efficient means of encryption; and the subsequent introduction of electronics and computing
has allowed elaborate schemes of still greater complexity, most of which are entirely unsuited to pen and
paper[1].
The development of cryptography has been paralleled by the development of cryptanalysis — the
"breaking" of codes and ciphers. The discovery and application, early on, of frequency analysis to the reading of
encrypted communications has, on occasion, altered the course of history. Thus the Zimmermann
Telegram triggered the United States' entry into World War I; and Allied reading of Nazi Germany's ciphers
shortened World War II, in some evaluations by as much as two years [4].
Before the modern era, cryptography was concerned solely with message confidentiality (i.e.,
encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again
at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the
key needed for decryption of that message). Encryption was used to (attempt to)
ensure secrecy in communications, such as those of spies, military leaders, and diplomats [7]. In recent decades,
the field has expanded beyond confidentiality concerns to include techniques for message integrity checking,
sender/receiver identity authentication, digital signatures, interactive proofs and secure computation, among
others [5].
Towards the close of the 20th century, the National Institute for Standards and Testing (NIST)acted on
the need for a new encryption algorithm capable of protecting top secret information[2].
NIST is part of the Department of Commerce. It is a non-regulatory agency that, promotes "U.S. innovation and
industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance
economic security and improve quality of life.
"Early in the development process, NIST decided to draw on the world's finest cryptographic minds
and asked them to submit candidates for the new algorithm because the aging Data Encryption Standard (DES)
has many weaknesses. DES has a relatively small 56-bit key which was becoming vulnerable to brute force
attacks. In addition, the DES was designed primarily for hardware and is relatively slow when implemented in
software. While Triple-DES avoids the problem of a small key size, it is very slow even in hardware; it is
unsuitable for limited-resource platforms; and it may be affected by potential security issues connected with the
(today comparatively small) block size of 64 bits. In 1997 NIST published a formal call which read in part: It is
intended that the AES will specify an unclassified, publicly disclosed encryption algorithm available royalty-
free worldwide that is capable of protecting sensitive government information well into the next century.

The purpose of this notice is to solicit candidate algorithms from the public, academic/research communities,
manufacturers, voluntary standards organizations, and Federal, state, and local government organizations.
Following the close of the submission period, NIST intends to make all submissions publicly available for
review and comment.
The entire process spanned five years. Fifteen competing algorithms with colorful names such as
Rijndael (the eventual winner), Twofish and Serpent (the runners up) were scrutinized over a three year period
[8].
AES is now the industry standard for encryption. The NSA employs it for protecting secret information
and industry uses the algorithm for creating commercially available encryption products[3].
File encryption and email encryption are two common applications for AES. File encryption protects the
information on your hard disk or thumb drive. With encryption, your data will be secure even if your computer
is hacked or your USB drive stolen. Email encryption protects your messages as they journey through the cloud
and keeps them from being read by unintended recipients.
II. AES algorithm overview:
AES Algorithm consists of 2 Main Parts:
1- Encryption or Decryption Process:
Encryption process contains 4 main parts:
I-Add Round Key:Each byte of the state is combined with the round key using bitwise Xor.
II-Shift Row: transposition step
III-Sub Byte: non-linear substitution step using Sbox
IIII-Mix Column: mixing operation of each column using GF
Encryption process: It starts with AddRoundKey with RoundKey0.
Then go to loop and do SubByte, ShiftRow,MixColumn and AddRoundKey in that order for 9 Rounds each
round with different RoundKey(1-9).
Then go to the final round (Round10) and repeat the same previous functions in the loop except MixColumn.
Decryption process: it’s the reverse of encryption process in every step which means the decryption 1st
round is
the 10th
round of the encryption and it uses the inverse functions of MixColumn, SubByte and ShiftRow and as
u can assume the Keys arrangement are reversed too as it starts with Roundkey10 instead of Roundkey0 as it
was in the encryption process [8] [3].
2-Key Generation (Key Expansion):
It involves RotWord, SubByte And Xor bitwise operation to generate enough keys for each round in the
Encryption, Decryption process.
Summary of both encryption and decryption process are shown in the Fig. 2.

As each round works with different key generated from the key generation process.
III. Implementation of AES Software and Hardware
AES-128 has been implemented on PIC18f452 using MIKROC PRO FOR PIC and interfaced it with
Keypad, Alphanumeric LCD 4x20, leds, buttons and Xbee Module for wireless communication as shown in fig.
3.
PIC18F452 pin diagram [6] is shown in fig. 4.
Keypad is used as an input device to enter the Plaintext, LCD is used to display both encrypted and decrypted
text, Xbee Module is used to send or receive the encrypted file from or to another exact same device, Leds is
used to indicate that there is text being received or the text is done being transmitted. The device can either
receive or send the encrypted text to another same device.

Overview on the code
1-SubByte
2-ShiftRow
3-MixColumn
4-AddRoundKey
IV. Advantage of Implementation
You will need to have the device to be able to decrypt the encrypted file because it uses custom Sbox
instead of the standard one to ensure more security and the security fuses in the PIC can be enabled so the PIC
won't be readable to protect the code hence protect the algorithm so even if the encrypted message got hacked
by any means in order to break the encrypted file you will need to have the device first and then guess the key
which is practically impossible.
V. Conclusion
In this paper the implementation of AES-128 has given it more encryption power and enhanced its
security even more thus make it harder for anyone to hack the ciphered information and decrypted it.
The device components are simple and cheap in price so the cost isn't a problem at all.
