Parallel Key Encryption for CBC and Interleaved CBC

In current day scenario, the need to protect information has become very important and hence the need for cryptographic algorithms is high. Here, we extend the parallel key encryption algorithm and bring out its full potential by implementing the various cryptographic modes such as cipher block chaining and interleaved cipher block chaining where commendable increase in efficiency and reduction...

Cap-binding complex (CBC)

The 7mG (7-methylguanosine cap) formed on mRNA is fundamental to eukaryotic gene expression. Protein complexes recruited to 7mG mediate key processing events throughout the lifetime of the transcript. One of the most important mediators of 7mG functions is CBC (cap-binding complex). CBC has a key role in several gene expression mechanisms, including transcription, splicing, transcript export an...

Marcas d'Água Frágeis de Autenticação para Imagens em Tonalidade Contínua e Esteganografia para Imagens Binárias e Meio-Tom

Watermark is an information-carrying signal embedded into digital data that can be extracted later to make some assertion about the data. Digital watermarks are usually classified as robust or fragile. Robust watermarks are designed to resist most image manipulating procedures and are used normally to attest the image ownership. Fragile watermarks are easily corrupted by any image processing pr...

Structural Binary CBC Encryption Mode

A block cipher is a kind of symmetric encryption algorithm that operates on blocks of fixed length, often 64 or 128 bits. It transforms blocks of plaintext into blocks of ciphertext of the same length under the provided secret key. A common characteristic of currently widely used modes of operation such as CBC, CFB and OFB is the sequential procedure, i.e., the encryption/decryption algorithm c...
