In the present mobile communication environment, lot of research is going on, to improve the performance of issues like handoffs, routing etc. Security is another key issue that needs to be considered, which comes into picture once the communication channel is set- up. Many security protocols are being proposed for different applications like Wireless Application Protocol, 802.11 etc. most of them are based on the public and private key cryptography. This paper provides an insight on these cryptographic protocols and also looks into the current research project going on at Sun Microsystems Lab on wireless security
