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...
متن کاملCap-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...
متن کاملStructural 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...
متن کاملOMAC: One-Key CBC MAC
In this paper, we present One-key CBC MAC (OMAC) and prove its security for arbitrary length messages. OMAC takes only one key, K (k bits) of a block cipher E. Previously, XCBC requires three keys, (k + 2n) bits in total, and TMAC requires two keys, (k + n) bits in total, where n denotes the block length of E. The saving of the key length makes the security proof of OMAC substantially harder th...
