Securing data transfer is a primary need for all embedded systems. The AES-ECC hybrid cryptosystem combines advantages of the Advanced Encryption Standard (AES) to accelerate data encryption and the Elliptic Curve Cryptography (ECC) to secure the exchange of symmetric session key. In this paper, we present an improved AES-ECC system using a co-design approach where AES runs on NIOS II softcore and...
Large-integers are integers with bit-size larger than 64 and mainly used in cryptography and computational alegbra. Large-integers arithmetic is constantly changing resulting in continuous new hardware implementations where operations are generally in multi-level within the same design. One of the shortcomings of hardware description languages libraries is their lack of support for large-integer's...
Elliptic Curve Cryptography have known, in recent years, an increasing success in security applications thanks to their advantages such as a short keys size with a high security level. Their popularity has led to various implementations in terms of algorithms, curves, coordinate systems, platforms, etc. The aim of this work is first to explore actual trends of ECC-based implementations in different...
