Secure and Fast Hashing Algorithm with Multiple Security Levels
Journal of Software, 2009 We propose a new secure and fast hashing algorithm with multiple security levels (SFHA-MSL). It is based on the generic 3C (3 compressions) construction and the 3C-X (3C XOR) hash function which is the simplest and efficient variant of the generic 3C hash function and it is the simplest modification to the Merkle-Damgard (M-D) iterated construction ...

A Perceptual Image Hashing Algorithm for Hybrid Document Security [PDF]
2017 14th IAPR International Conference on Document Analysis and Recognition (ICDAR), 2017 In order to create an automatic document security system one needs to secure the textual content but also the graphical content of the document. This paper proposes a hashing algorithm capable of securing the graphical parts of paper and digital documents with unprecedented performance and a very small digest.

On the Gold Standard for Security of Universal Steganography [PDF]
, 2018 While symmetric-key steganography is quite well understood both in the information-theoretic and in the computational setting, many fundamental questions about its public-key counterpart resist persistent attempts to solve them.
