Steganography is the art and science of concealing a message within another message without drawing some suspicion to others so that the message can only be identified by its intended recipient.There are various techniques of text steganography which are as follows −Line-shift coding − Features are marked into the text ...

Text steganography is an approach of hiding secret text message within another text as a covering message or creating a cover message associated to the initial secret message.Text steganography can include anything from transforming the formatting of an existing text, to changing words within a text, to producing random character ...

Steganography is the art and science of connecting which hides the presence of the communication. The purpose of steganography is to convey a message to a receiver in such a method that the very presence of the message is indistinguishable by a third party.In the computer world, steganography means hiding ...

Steganography is an approach that facilitates concealing of a message that is to be kept secret inside other message. This result is the concealment of the secret message itself.Steganography approach can be used to images, a video file or an audio file. Generally, however, steganography is written in characters such ... Read More

Cryptanalysis is the decryption and inquiry of codes, ciphers or encrypted text. Cryptanalysis need numerical rule to search for algorithm susceptibility and divide into cryptography or information security systems.The main objective of cryptanalysis is to discover weaknesses in or otherwise defeat encryption algorithms. This research can be used by cryptographers ... Read More

There are various classification of security attack is as follows −Cryptanalytic attacks − These attacks are combination of statistical and algebraic techniques objective at make sure the secret key of a cipher. These technique inspect the numerical properties of the cryptographic algorithms and aims at discovering distinguishers of the output ... Read More

There are various types of security mechanism which are as follows −Physical Security − Physical security define limiting access to key network resources by maintaining the resources behind a locked door and secured from natural and human-made disasters.Physical security can secure a network from unintended exploitation of network equipment by ...

There are various security services which are as follows −Message Confidentiality − The principle of confidentiality defines that only the sender and the intended recipient should be capable to create the element of the message. It protects the transmitted data from passive attack.Confidentiality can be used at several levels on ... Read More

A true random number generator (TRNG) uses a nondeterministic source to make randomness. Most function by measuring unpredictable natural processes, including pulse detectors of ionizing radiation activities, gas discharge tubes, and leaky capacitors.Intel has developed a commercially accessible chip that samples thermal noise by developing the voltage measured across undriven ...

A Feistel cipher is a cryptographic approach used in the construction of block cipherbased algorithms and structure. A Feistel network implements a sequence of iterative ciphers on a block of information and is frequently designed for block ciphers that encrypt huge quantities of data.A Feistel network operates by splitting the ...
