In this paper we analyze the cryptanalysis of the simplified data encryption standard algorithm using metaheuristics
and in particular genetic algorithms. The classic fitness function when using such an algorithm
is to compare n-gram statistics of a the decrypted message with those of the target message. We show that
using such a function is irrelevant in case of Genetic Algorithm, simply because there is no correlation
between the distance to the real key (the optimum) and the value of the fitness, in other words, there is no
hidden gradient. In order to emphasize this assumption we experimentally show that a genetic algorithm
perform worse than a random search on the cryptanalysis of the simplified data encryption standard
algorithm.

The Two-Sided Job Interview: Expanding the Job Seeker's Role in the Hiring Pr...Erica Starr
In light of the not-so-great job market, this post is all about how important it is to ask questions at a job interview. Interviewers want to know you've done your research, and they expect you ask questions about the company and/or the specific position you are interviewing for.
Secure routing path using trust values forijcisjournal
Traditional cryptography-based security mechanisms such as authentication and authorization are not
effective against insider attacks like wormhole, sinkhole, selective forwarding attacks, etc., Trust based
approaches have been widely used to counter insider attacks in wireless sensor networks. It provides a
quantitative way to evaluate the trustworthiness of sensor nodes. An untrustworthy node can wreak
considerable damage and adversely affect the quality and reliability of data. Therefore, analyzing the trust
level of a node is important. In this paper we focused about indirect trust mechanism, in which each node
monitors the forwarding behavior of its neighbors in order to detect any node that behaves selfishly and
does not forward the packets it receives. For this, we used a link state routing protocol based indirect
trusts which forms the shortest route and finds the best trustworthy route among them by comparing the
values of all the calculated route trusts as for each route present in the network. And finally, we compare
our work with similar routing protocols and show its advantages over them.
Secure Image Transfer in The Domain Transform DFTijcisjournal
This paper presents a new approach for secure image transmission. It consists of three treatments including: a compression based on Discrete Fourier Transform (DFT), a use of symmetric encryption Advanced Encryption Standard (AES) and a Data Hidden Insertion technique for the transport of sensitive information.
With the web becoming more and more influential in people’s buying decisions, you can can no longer afford to get your website wrong – it could literally be the difference between a flourishing practice and struggle street.
The good news is that it is pretty easy to ensure your website becomes your hardest working salesperson.
In this session we will break through the technical mumbo jumbo and help you understand how to maximise the potential of your website. You will learn:
How Smartphones and Tablets are changing the way your visitors see your site – are people seeing you in your best light?
How omitting this one crucial part of your site can mean your visitors won’t ever return to your site – AGAIN! Resulting in loss of revenue & reputation.
Why these 5 things will make visitors leave your site as quickly as they arrived – as well as how to change them to keep visitors for longer and start building loyal fans.
A PAIRING-FREE IDENTITY BASED TRIPARTITE SIGNCRYPTION SCHEMEijcisjournal
The certificate-based cryptosystems is traditional way in providing the system parameters. Identity-based
cryptography is more efficient than certificate-based cryptosystems. Each user in identity-based
cryptography uses any arbitrary string that uniquely identifies him as his public key. This paper proposes
a new identity-based tripartite signcryption scheme based on the elliptic curve discrete logarithm problem.
The proposed id-based tripartite signcryption scheme does not use the bilinear pairings in both the
Signcryption and unsigncryption phases. The proposed scheme used to reduce the communication over
head when three entities wants to communicate securely as in authentication protocol in GSM and in ecommerce.
The proposed scheme satisfies various desirable security properties. Also, the performance of
the proposed scheme is tested.
Email Marketing - The Secret Weapon To Grow Your BusinessWarren Denley
Getting the right people to your site is hard enough. And making a sale to first time visitors is nearly impossible. So you need a way to build a relationship with your visitors and keep them coming back to your site until they are ready to buy from you.
