Steganography from weak cryptography

We introduce a problem setting which we call ``the freedom fighters' problem''. It subtly differs from the prisoners' problem. We propose a steganographic method that allows Alice and Bob to fool Wendy the warden in this setting. Their messages are hidden in encryption keys. The recipient has no prior knowledge of these keys, and has to cryptanalyze ciphertexts in order to recover them. We show an example of the protocol and give a partial security analysis

Steganographically Encoded Data

Steganography is the art of hiding information in ways that prevent its detection. Though steganography is an ancient craft, the onset of computer technology has given it new life. Computer-based steganographic techniques introduce changes to digital covers to embed information foreign to the native covers. Such information may be communicated in the form of text, binary files, or provide additional information about the cover and its owner such as digital watermarks or fingerprints. This paper explains steganography, provides a brief history and describes how steganography is applied in hiding information in images.Steganography, information hiding, digital image, digital watermarking

Security in Wireless Sensor Networks: Issues and Challenges

Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various futuristic applications both for mass public and military. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats. The intent of this paper is to investigate the security related issues and challenges in wireless sensor networks. We identify the security threats, review proposed security mechanisms for wireless sensor networks. We also discuss the holistic view of security for ensuring layered and robust security in wireless sensor networks.Comment: 6 page

Transaction Document Security Protection in the Form of Image File, Jpg or Tif Interbank Transfer Using Steganography and Cryptography

 Information security process can be done by hiding the information on other media or by certain methods, so that other people do not realize there is some information in the media. Technique known as Steganography and Cryptography. Steganography is a technique to hide or disguise the existence of secret messages in the media reservoirs. While Cryptography disguise the meaning of a message, but do not hide that there is a message. In a bank cannot be separated in the presence of inter-bank transactions which transfer if the transfer interbank transactions done in branch offices and nominal transaction exceeds the transaction limit branch offices will require official approval in the upper branch. How do I prove the authenticity of the document transfer transaction? Therefore, a company in the banking sector needs to be a medium to prove the validity of the document sent by the branch transaction. In this case the author has designed an application with a blend of steganography and cryptography techniques that can be used in testing the validity of the transaction document. By using steganographic techniques undercover in a media that has brought and cryptographic key assignment as random, then the document that is sent in the branch office can be proved

Security during Transmission of Data Using Web Steganography

The project entitled Steganography is to give security to a content record. Since the security of the data over the internet has raised a concern to the people. There are many methods to protect the data from going into the access of unauthorized people. Steganography can be used along with the encryption technique to secure the data. Steganography is used to hide the data or a secret message whereas cryptography is used to encrypt the message and make it difficult the people to read. So, the proposed system is to combine both steganography and cryptography for the secret data transmission. The transmission can be done by using an image as a carrier of data. This paper uses high-performance BMP steganography along with a substitution encryption methodology. The approach that is used here is IDEA (International Data Encryption Algorithm) algorithm which is used for encryption. The IDEA algorithm works as follows, it will take the TEXT document and mystery key as the input and gives the encrypted and BMP picture as the output for the sender side. There can additionally be “Voice Recognition System” framework so that it can use voice to decrypt the message. This is the future expansion or scope of this paper
