The session initiation protocol (SIP) has been receiving a lot of attention to provide security in the Voice over IP (VoIP) in Internet and mobility management. Recently, Yeh et al. proposed a smart card-based authentication scheme for SIP using elliptic curve cryptography (ECC). They claimed that their scheme is secure against known security attacks.(More)
This paper investigates the buckling behavior of piezoelectric nanowires under distributed transverse loading, within the framework of the Timoshenko beam theory, and in the presence of surface effects. Analytical relations are given for the critical force of axial buckling of nanowires by accounting for the effects of surface elasticity, residual surface(More)
