    Dual stage text steganography using unicode homoglyphs
    (Springer Verlag service@springer.de, 2015) Hosmani, S.; Bhat, H.G.R.; Chandrasekaran, K.
    Text steganography is hiding text in text. A hidden text gets hidden in a cover text to produce a plain looking stego text. This plain looking stego text is posted as the message which no one suspects to contain anything concealed. Today, text messages are a common mode of communication over the internet and it is associated with a huge amount of traffic. Steganography is an added layer of protection that can be used for security and privacy. In this paper, we describe a text steganography approach that provides a good capacity and maintains a high difficulty of decryption. We make use of approaches of space manipulation, linguistic translation and Unicode homoglyphs in our algorithm. Our implementation is in Python. Also, we explain a parallel approach for hiding large hidden text messages in large cover text messages. © Springer International Publishing Switzerland 2015.

    DANE: An inbuilt security extension
    (Institute of Electrical and Electronics Engineers Inc., 2016) Aishwarya, C.; Raghuram, M.A.; Hosmani, S.; Sannidhan, M.S.; Rajendran, B.; Chandrasekaran, K.; Bindhumadhava, B.S.
    Use of TSL and certificates in secure applications in the internet is very common today. Certificate authorities are playing the important role of trust anchors. But this means that third party certificate authorities have to be trusted by both domain owners and their clients. Compromises of certificate authorities will put many users under a huge risk. To solve this problem, the DANE protocol was proposed that is used on top of DNSSEC. It allows using the chain of trust in DNS for authenticating certificates and makes clients impose many constraints on the certificates they receive. We analyze the performance of the DANE protocol at the client side and also present a tool for deploying and administrating DANE with BIND servers in a local network. © 2015 IEEE.
