Abstract

Most of all, it is my great pleasure to share with you the news that our journal belongs to Q2 class as well as has 1.73 cites per doc according to Scopus. Indeed, it is a meaningful achievement, which makes us proud. This third issue of 2014 collects six papers, most of which are extended from the selected papers presented at the 2014 Asian Conference on Availability, Reliability and Security (AsiaARES 2014)1.  The first article “Efficient variant of Rainbow using sparse secret keys” [1] focuses on improving Rainbow, which is a Multivariate Public Key Cryptosystems (MPKC) digital signature scheme. The authors combine two variants of Rainbow, which reduce the secret key size and accelerate the signature generation by using sparse secret keys. As a result, the combined scheme achives smaller key size as well as more efficient signature generation than those of the two variants.
