Another technique is to use low data path width vompact AES design in order to reduce the power consumption [ 21 a-box. Architectural Optimization for a 1.

Tiltech [ 24 ] describes a total of eight different implementations of the AES S-box in which he grouped them into three basic categories: Wolkerstorfer [ 5 ]. This contribution is acknowledged. The second better performance comes from Nabihah [ 34 ] with very good critical path delay.

A Novel Byte-Substitution Architecture for the AES Cryptosystem

Therefore, less switching activities ensure lower power consumption. The main constrain is appeared when considered the critical path versus the area-power product. J Electron Potimization This paper approaches a single stage decoder function which performs better compared to Bertoni.

It can be observed that the more bytes processed in parallel, the more area and power are needed and the less delay is required. On the other hand, Implementations which calculate the S-box transformation in hardware were first proposed by Wolkerstorfer et al. Now-a-days there are a lot of applications coming in the market where an increasing number of battery-powered embedded systems like PDAs, cell phones, networked sensors, smart cards, RFID etc.


The T-box AES design is intended to have high throughput and low power usage [ 20 ].

Logically, the SubBytes transformation substitutes all of the 16 bytes of the state independently using the S-box. The other two approaches consume three times as much power as the proposed design, while hw-lut [ 24 ] consumes about four times more power. Total dynamic power dissipation copact S-box is obtained 1. State of the Art in Hardware Architectures K. All the 4-to—1 multiplexers implemented are constructed using three 2-to—1 multiplexers for simplicity Fig 4 C.

The remainder of this paper is organized as follows.

Hodjat A, Verbauwhede I, A Elazm [ 28 ] shows a composite Galois Field o;timization of S-box to reduce the size and the delay of the circuit. In case of hardware, on the other hand, the implementation of the S-box is directed to the desired trade-off among area, delay, and power consumption. The next Section shows the proposed S-box architecture in detail.

However, it may be necessary to add a large number of additional flip-flops when the pipeline stage is placed between the decoder and encoder.

We conclude in Section 7. Graphical SAC analysis of [S. This paper focuses on the solution of this particular problem and has presented a novel technique in designing a low power, least delay and area efficient S-box for an AES processor.

The resources that have been utilized are provided in Table 1.
