Abstract

A Novel Structure with Dynamic Operation Mode for Symmetric-Key Block Ciphers

“…In the recent research called multi-mode, one type multi-mode cascades operations with the same data block [10], and another type cascades operations in the same session [11]. The related works about multi-mode and multicipher, we explore Crypto-coprocessors and multi-cipher cryptosystem [12][13][14] [15]. NOPcycle-padding algorithm (NCPA) [15] is one of those re-configurable cryptosystems used for hardware acceleration.…”

The Unified Operation Structure for Symmetric-Key Algorithm

“…The related works about Multi-mode and Multi-cipher, we explore Cryptocoprocessors and Multi-cipher cryptosystem [8] [9][10] [11]. Multi-cipher and multi-mode cryptosystems are widely used for hardware acceleration in modern security protocols, such as SSL and IPsec.…”

“…Crypto-coprocessor like CryptoManiac (CM) [8] processor is a flexible crypto-coprocessor which supports multiple cipher algorithms and multi-mode operations. Research [7] introduces a multicipher cryptosystem (MCC) which enables a cryptosystem to use multiple cipher algorithms concurrently in a session of communication.…”

Validating Word-Oriented Processors for Bit and Multi-word Operations

“…For programmable solutions, new instructions were proposed to accelerate symmetric-key ciphers in general-purpose processors [3], and in cryptographic coprocessors like Cryptomaniac [4] for ciphers used in secure networking protocols. In contrast, we do not propose any specific new instructions in this paper, but rather new methodologies for bringing more data to the functional units.…”
