Substitution box (S-box) is a critical part of the data encryption and decryption procedures. The primary function of the S-box in advanced encryption standard algorithm is to randomize the 8-bit input into 8-bit output. This paper presents a novel approach to S-box construction based on the replacement of irreducible polynomial and affine mapping. The strength of the created S-box is assessed by...
S-box plays a major role in the AES algorithm. The strength of S-box depends on the design and algebraic constructions. In this paper, the construction of S-box will be built using a basic polynomial equation and the addition of a constant 8-bit vector different from the standard AES. The quality of the created S-box is evaluated by measuring several standard criteria such as nonlinearity, strict...
The femtocell network has currently been considered as one of the most promising networking technologies. Nevertheless, due to dense deployment, interference generated by nearby femto base station (FBS) is expected to significantly degrade the signal to interference plus noise ratio (SINR) of femto users (FUEs). Ineffective resource block combination is one of the culprits behind the reduction in...
Nowadays, the demand of embedded processors has been increasing rapidly. However, the design time required for producing a new processor can not catch up the time-to-market demand. In order to solve this problem, a modeling tool which allows designer to crate new hardware and estimate its performace without having the physical products is very important. SystemC is one among existing modeling tools...
A number of researchers have proposed numerous methods in fingerprint matching aspect, especially, in term of speed and memory consumption for decades. However, the problem of the matching accuracy remains until recent days, which is obviously caused by distortions. In this paper, the Two Level of Scoring System is an extension modified from original Hough transform (HT) approach, which is proposed...
Bio-encryption is a concept that aims to improve the traditional cryptographic security by combining biometrics and cryptography. Fuzzy Vault scheme is a bio-encryption method which is very famous for its ability to handle fuzzy biometric data while at the same time combines them with cryptographic mechanism. Moreover, Fuzzy Vault scheme is claimed as a bio-encryption method that can be deployed in...
