چکیده

We propose a new block cipher LEA, which has 128-bit block size and 128, 192, or 256-bit key size. It provides a high-speed software encryption on general-purpose processors. Our experiments show that LEA is faster than AES on Intel, AMD, ARM, and ColdFire platforms. LEA can be also implemented to have tiny code size. Its hardware implementation has a competitive throughput per area. It is secure against all the existing attacks on block ciphers.

First Experimental Result of Power Analysis Attacks on a FPGA Implementation of LEA

The lightweight encryption algorithm (LEA) is a 128-bit block cipher introduced in 2013. It is based on Addition, rotation, XOR operations for 32-bit words. Because of its structure, it is useful for several devices to achieve a high speed of encryption and low-power consumption. However, side-channel attacks on LEA implementations have not been examined. In this study, we perform a power analy...

Compact Implementations of LEA Block Cipher for Low-End Microprocessors

In WISA’13, a novel lightweight block cipher named LEA was released. This algorithm has certain useful features for hardware and software implementations, i.e., simple ARX operations, non-S-box architecture, and 32-bit word size. These features are realized in several platforms for practical usage with high performance and low overheads. In this paper, we further improve 128-, 192and 256-bit LE...

How to Maximize Software Performance of Symmetric Primitives on Pentium III and 4

This paper studies the state-of-the-art software optimization methodology for symmetric cryptographic primitives on Pentium III and 4 processors. We aim at maximizing speed by considering the internal pipeline architecture of these processors. This is the first paper studying an optimization of ciphers on Prescott, a new core of Pentium 4. Our AES program with 128-bit key achieves 251 cycles/bl...

ICEBERG : An Involutional Cipher Efficient for Block Encryption in Reconfigurable Hardware

We present a fast involutional block cipher optimized for reconfigurable hardware implementations. ICEBERG uses 64-bit text blocks and 128-bit keys. All components are involutional and allow very efficient combinations of encryption/decryption. Hardware implementations of ICEBERG allow to change the key at every clock cycle without any performance loss and its round keys are derived “on-the-fly...
