Nonlinear n-stage feedback shift-register sequences over the finite field Fq of period qn − 1 are investigated under linear operations on sequences. We prove that all members o...
In this paper, we discuss some methods of constructing frequency/time hopping (FH/TH) sequences over GF(pk ) by taking successive k-tuples of given sequences over GF(p). We are abl...
We present constructions of polyphase sequences suitable for the use as codewords in orthogonal frequency-division multiplexing (OFDM) with strictly bounded peak-to-mean envelope p...
A secret handshake mechanism allows two entities, members of a same group, to authenticate each other secretly. This primitive was introduced recently by Balfanz, Durfee, Shankar, ...
We present a practical protection mechanism against SQL injection attacks. Such attacks target databases that are accessible through a web frontend, and take advantage of flaws in...
