Complexity of embedded systems becomes more and more popular which integrates a hardware and software parts on common platform. This complexity can be inferred on the performance of such systems. This paper, explains the characteristics of LEON3 Soft Core processor and its implementation for several configurations, including single, dual, tri, and quad cores, as well as with and without the hardware...
Embedded system design is characterized by its complexity day by day, combined with reduced time-to-market deadlines. An embedded system integrates together a hardware and software parts on a common platform. The Advanced Encryption Standard (AES) is a cryptographic algorithm that can be used to encrypt a huge bulk of data and for embedded system security. This paper, explains the characteristics...
In this paper we describe a hardware implementation of a low resource digital signature design using Elliptic Curve Digital Signature Algorithm (ECDSA). The implementation of ECDSA is based on the recommended GF (2163) NIST Elliptic Curve Cryptography (ECC). Elliptic curve based systems can be implemented with much smaller parameters, leading to significant performance advantages. Such performance...
Embedded processors are an integral part of many communications devices such as mobile phones, secure access to private networks, electronic commerce and smart cards. However, such devices often provide critical functions that could be sabotaged by malicious entities. The supply of security for data exchange on basis of embedded systems is a very important objection to accomplish. This paper focuses...
Recently, much research has been conducted for security of data transactions on embedded platforms. Advanced Encryption Standard (AES) is considered as one of a candidate algorithm for data encryption/decryption. One important application of this standard is cryptography on smart cards. In this paper we describe a 32-bits architecture developed for Rijndael algorithm to accelerate execution on 32-bits...
