Initialising and managing security parameters for personal mobile devices within a Personal Area Network (PAN) presents a variety of security problems. In this paper we consider one possible paradigm for mobile device security management, namely the use of a ‘personal CA’ to provide certificates within a PAN. The security requirements for such a personal CA are analysed, and a novel protocol fo...

Let T be a unit equilateral triangle, and T1, . . . , Tn be n equilateral triangles that cover T and satisfy the following two conditions: (i) Ti has side length ti (0 < ti < 1); (ii) Ti is placed with each side parallel to a side of T . We prove a conjecture of Zhang and Fan asserting that any covering that meets the above two conditions (i) and (ii) satisfies ∑n i=1 ti ≥ 2. We also show that ...
