To solve the privacy-preserving problem during the roaming authentication of wireless mobile networks, a novel roaming authentication scheme with anonymity was presented.An efficient certificateless aggregate signature scheme was first constructed, by introducing the online/offline signature and combining the aggregate signature.Com-pared with rumc
This paper presents a current converter that uses an inductor based approach for interim energy storage.A family of the circuits for step down conversion is examined for both non-inverting and inverting operations.The paper has disclosed the method of the generation, so that any order of 1/n conversion ratio can be made.One of the features is to us
We present 5326058hx a fast, reliable and inexpensive restriction-free cloning method for seamless DNA insertion into any plasmid without sequence limitation.Exponential megapriming PCR (EMP) cloning requires two consecutive PCR steps and can be carried out in one day.We show that EMP cloning has a higher efficiency than restriction-free (RF) cloni
