Review on DNA Cryptography
Cryptography is the science that secures data and communication over the
network by applying mathematics and logic to design strong encryption methods.
In the modern era of e-business and e-commerce the protection of
confidentiality, integrity and availability (CIA triad) of stored information
as well as of transmitted data is very crucial. DNA molecules, having the
capacity to store, process and transmit information, inspires the idea of DNA
cryptography. This combination of the chemical characteristics of biological
DNA sequences and classical cryptography ensures the non-vulnerable
transmission of data. In this paper we have reviewed the present state of art
of DNA cryptography.Comment: 31 pages, 12 figures, 6 table
EVALUATION OF CRYPTOGRAPHIC ALGORITHMS
This article represents a synthesis of the evaluation methods for cryptographic algorithms and of their efficiency within practical applications. It approaches also the main operations carried out in cryptanalysis and the main categories and methods of attack in order to clarify the differences between evaluation concept and crypto algorithm cracking.cryptology, cryptanalysis, evaluation and cracking cryptographic algorithms
Session Initiation Protocol Attacks and Challenges
In recent years, Session Initiation Protocol (SIP) has become widely used in
current internet protocols. It is a text-based protocol much like Hyper Text
Transport Protocol (HTTP) and Simple Mail Transport Protocol (SMTP). SIP is a
strong enough signaling protocol on the internet for establishing, maintaining,
and terminating session. In this paper the areas of security and attacks in SIP
are discussed. We consider attacks from diverse related perspectives. The
authentication schemes are compared, the representative existing solutions are
highlighted, and several remaining research challenges are identified. Finally,
the taxonomy of SIP threat will be presented
