The conjugacy search problem in a group G is the problem of recovering an x G from given g G and h = x-1 gx. This problem is in the core of several recently suggested public key ...
Abstract. Wireless Sensor Networks (WSN) are becoming a key technology in the support of pervasive and ubiquitous services. The previous notion of “PKC is too expensive for WSNâ€...
In this work, we study a new multivariate quadratic (MQ) assumption that can be used to construct public-key encryption schemes. In particular, we research in the following two di...
This paper intends to provide information about up-to-date performances of smart-card arithmetic coprocessors regarding major public-key cryptosystems and analyze the main tendence...
