Abstract. Key authentication is very important in secret communications and data security. Recently, Lee, Hwang and Li proposed a new public key authentication scheme for cryptosys...
A finite element method of the penalization type, using higher order shape functions with rectangular elements, is presented for the solution of the Stokes flow. The fluid is visc...
