A depth-16 circuit for the AES S-box
نویسندگان
چکیده
New techniques for reducing the depth of circuits for cryptographic applications are described and applied to the AES S-box. These techniques also keep the number of gates quite small. The result, when applied to the AES S-box, is a circuit with depth 16 and only 128 gates. For the inverse, it is also depth 16 and has only 127 gates. There is a shared middle part, common to both the S-box and its inverse, consisting of 63 gates.

متن کاملHardware Implementation of Dynamic S-BOX to Use in AES Cryptosystem
One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...
متن کاملSeveral Masked Implementations of the Boyar-Peralta AES S-Box
Threshold implementation is a masking technique that provides provable security for implementations of cryptographic algorithms against power analysis attacks. In recent publications, several different threshold implementations of AES have been designed. However in most of the threshold implementations of AES, the Canright S-Box has been used. The Boyar-Peralta S-Box is an alternative implement...
متن کاملA New S-box Structure Named Affine-power-affine
In this paper, we consider the problem of the simple algebraic structure of the Advanced Encryption Standard (AES) S-box, in which only 9 terms are involved in the algebraic expression, while its inverse S-box involves 255 terms. By resolving the reason why the algebraic expressions of AES-like S-boxes are so simple, the upper bound of items involved in the algebraic expressions of AES-like S-b...
متن کاملLow-Power Side-Channel Attack-Resistant Asynchronous S-Box Design for AES Cryptosystem
A novel asynchronous combinational S-Box (substitution box) design for AES (Advanced Encryption Standard) cryptosystems is proposed and validated. The S Box is considered as the most critical component in AES crypto-circuits since it consumes the most power and leaks the most information against side-channel attacks. The proposed design is based on a delay-insensitive logic paradigm known as Nu...
