A Review on Biological Inspired Computation in Cryptology
Cryptology is a field that concerned with cryptography and cryptanalysis. Cryptography, which is a key technology in providing a secure transmission of information, is a study of designing strong cryptographic algorithms, while cryptanalysis is a study of breaking the cipher. Recently biological approaches provide inspiration in solving problems from various fields. This paper reviews major works in the application of biological inspired computational (BIC) paradigm in cryptology. The paper focuses on three BIC approaches, namely, genetic algorithm (GA), artificial neural network (ANN) and artificial immune system (AIS). The findings show that the research on applications of biological approaches in cryptology is minimal as compared to other fields. To date only ANN and GA have been used in cryptanalysis and design of cryptographic primitives and protocols. Based on similarities that AIS has with ANN and GA, this paper provides insights for potential application of AIS in cryptology for further research
Grayscale Image Authentication using Neural Hashing
Many different approaches for neural network based hash functions have been
proposed. Statistical analysis must correlate security of them. This paper
proposes novel neural hashing approach for gray scale image authentication. The
suggested system is rapid, robust, useful and secure. Proposed hash function
generates hash values using neural network one-way property and non-linear
techniques. As a result security and performance analysis are performed and
satisfying results are achieved. These features are dominant reasons for
preferring against traditional ones.Comment: international journal of Natural and Engineering Sciences

Risks and remedies in e-learning system
One of the most effective applications of Information and Communication
Technology (ICT) is the emergence of E-Learning. Considering the importance and
need of E-Learning, recent years have seen a drastic change of learning
methodologies in Higher Education. Undoubtedly, the three main entities of
E-Learning system can be considered as Student, Teacher & Controlling Authority
and there will be different level, but a good E-Learning system needs total
integrity among all entities in every level. Apart from integrity enforcement,
security enforcement in the whole system is the other crucial way to organize
the it. As internet is the backbone of the entire system which is inherently
insecure, during transaction of message in E-Learning system, hackers attack by
utilising different loopholes of technology. So different security measures are
required to be imposed on the system. In this paper, emphasis is given on
different risks called e-risks and their remedies called e-remedies to build
trust in the minds of all participants of E-Learning system
