This document presents Bastion, a new encryption scheme that aims to ensure data confidentiality even if the encryption key is exposed. Bastion uses block cipher encryption in counter mode to encrypt plaintext data into ciphertext blocks. It then applies an efficient linear transformation to the ciphertext blocks. This linear transformation distributes information across all ciphertext blocks such that any individual block provides no information about the plaintext, even with knowledge of the encryption key. The scheme is designed to preserve confidentiality as long as an adversary does not have access to more than one ciphertext block. The document analyzes the security and performance of Bastion and suggests it could be integrated into existing cloud storage systems with low overhead.

Improvement of Search Algorithm for Integral Distinguisher in Subblock-Based ...ijcisjournal
Integral distinguisher is the main factor of integral attack. Conventionally, higher order integral distinguisher is obtained as an extension of first order integral (conventional algorithm). The algorithm was applied to many subblock-based block ciphers, however, the conventional algorithm has some problems. We find other integral distinguisher of two sub block-based block ciphers, TWINE and LBlock, which are different from the conventional evaluations. As a solution, we propose a new algorithm to search for higher order integral distinguisher. The point of a proposal algorithm is exploitation of bijective and injective components of cipher functions. Applying the proposal algorithm to TWINE and LBlock, we confirm the results of the proposal algorithm are consistent with the results which are calculated from computer experiment. The results are the optimal distinguisher and the most advantageous one for the attackers. Our proposal algorithm contributes to development of stronger block ciphers by obtaining such integral distinguisher.

Symmetric cryptography will always produce the same ciphertext if the plaintext and the given key are the same repeatedly. This condition will make it easier for cryptanalysts to perform cryptanalysis. This research introduces a one-to-many cryptography scheme, which can produce different ciphertexts even if the input given is the same repeatedly. The one-to-many encryption scheme can produce several ciphertexts with differences of up to 50%. The avalanche effect test obtained an average of 52.20%, better than modern cryptography Blowfish by 25.46% and 6% better than advanced encryption standard (AES). One-to-many can produce different n-ciphertexts, which will certainly make it more difficult for cryptanalysts to perform cryptanalysis and require n-times longer to break than other symmetric cryptography.

FPGA Implementation of A New Chien Search Block for Reed-Solomon Codes RS (25...IJERA Editor
The Reed-Solomon codes RS are widely used in communication systems, in particular forming part of the specification for the ETSI digital terrestrial television standard. In this paper a simple algorithm for error detection in the Chien Search block is proposed. This algorithm is based on a simple factorization of the error locator polynomial, which allows reducing the number of components required to implement the proposed algorithm on FPGA board. Consequently, it reduces the power consumption with a percentage which can reach 50 % compared to the basic RS decoder. First, we developed the design of Chien Search Block Second, we generated and simulated the hardware description language source code using Quartus software tools,finally we implemented the proposed algorithm of Chien search block for Reed-Solomon codesRS (255, 239) on FPGA board to show both the reduced hardware resources and low complexity compared to the basic algorithm.
“Proposed Model for Network Security Issues Using Elliptical Curve Cryptography”IOSR Journals
Abstract: Elliptic Curve Cryptography (ECC) plays an important role in today’s public key based security
systems. . ECC is a faster and more secure method of encryption as compared to other Public Key
Cryptographic algorithms. This paper focuses on the performance advantages of using ECC in the wireless
network. So in this paper its algorithm has been implemented and analyzed for various bit length inputs. The
Private key is known only to sender and receiver and hence data transmission is secure.
Elliptic Curve Cryptography (ECC) provides a secure
means of key exchange between communicating nodes using the
Diffie-Hellman (DH) Key Exchange algorithm. This work
presents an ECC encryption implementation using of the DH
key exchange algorithm. Both encryption and decryption of text
messages using this algorithm, have been attempted. In ECC,
encoding is carried out by mapping a message character to an
affine point on an elliptic curve. It can be observed from the
comparison of the proposed algorithm and Koblitz’s encoding
method, that the proposed algorithm is as secure as Koblitz’s
encoding method and the proposed algorithm has less
computational complexity as the encoding phase is eliminated
altogether. Hence, energy efficiency of the crypto system is
improved and the same can be used in resource constrained
applications, such as Wireless sensor networks (WSNs). It is
almost infeasible to attempt a brute force attack. The security
strength of the algorithm is proportional to the key length.
However, any increase in the key length results in more
communication overhead due to encryption.
SECURED WIRELESS COMMUNICATION THROUGH SIMULATED ANNEALING GUIDED TRAINGULARI...cscpconf
In this paper, simulated annealing guided traingularized encryption using multilayer perceptron generated session key (SATMLP) has been proposed for secured wireless ommunication. Bothsender and receiver station uses identical multilayer perceptron and depending on the final output of the both side multilayer perceptron, weights vector of hidden layer get tuned in bothends. After this tunning step both perceptrons generates identical weight vectors which is consider as an one time session key. In the 1st level of encryption process traingularized sub key1 is use to encrypt the plain text. In 2nd level of encryption simulated annealing method helps to generates sub key 2 for further encryption of 1st level generated traingularized encrypted text. Finally multilayer perceptron generated one time session key is used to perform
3rd level of encryption of 2nd level generated encrypted text. Recipient will use same identical multilayer perceptron guided session key for performing deciphering process for getting the simulated annealing guided intermediate cipher text. Then using sub key 2 deciphering technique is performed to get traingularized encrypted text. Finally sub key 1 is used to generate the plain text. In this proposed technique session key is not transmitted over public channel apart from few data transfers are needed for weight simulation process. Because after synchronization process both multilayer perceptron generates identical weight vector which acts as a session key. Parametric tests are done and results are compared in terms of ChiSquare test, response time in transmission with some existing classical techniques, which shows comparable results for the proposed system.

Novel Algorithm For Encryption:Hybrid of Transposition and Substitution MethodIDES Editor
This paper presents an algorithm which is hybrib of
Transposition and Substitution method.The main advantage
of this approach is ,it doesn’t use any key from outside because
key is present within the original message.Due to this the
main problem of exchanging keys securely is solved.Both Transposition
and Substitution method have their own limitations.So
we use both these method so that the resultant cipher is more
secure and strong.
Multilayer Perceptron Guided Key Generation through Mutation with Recursive R...pijans
In this paper, a multilayer perceptron guided key generation for encryption/decryption (MLPKG) has been
proposed through recursive replacement using mutated character code generation for wireless
communication of data/information. Multilayer perceptron transmitting systems at both ends accept an
identical input vector, generate an output bit and the network are trained based on the output bit which is
used to form a protected variable length secret-key. For each session, different hidden layer of multilayer
neural network is selected randomly and weights or hidden units of this selected hidden layer help to form
a secret session key. The plain text is encrypted using mutated character code table. Intermediate cipher
text is yet again encrypted through recursive replacement technique to from next intermediate encrypted
text which is again encrypted to form the final cipher text through chaining , cascaded xoring of multilayer
perceptron generated session key. If size of the final block of intermediate cipher text is less than the size of
the key then this block is kept unaltered. Receiver will use identical multilayer perceptron generated
session key for performing deciphering process for getting the recursive replacement encrypted cipher text
and then mutated character code table is used for decoding. Parametric tests have been done and results
are compared in terms of Chi-Square test, response time in transmission with some existing classical
techniques, which shows comparable results for the proposed technique.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
