Cryptography locks down WAP and P2P transmissions

Monday, 18 August 2003, 8:03 AM EST

No matter what protocol or architecture you're using to broadcast data through the air, encryption can make that data safer. In this article, we'll examine some places where encryption can help secure wireless applications and networks, with a particular focus on WAP and P2P architectures. We'll also look at a J2ME application that uses cutting-edge cryptographical libraries to encode its data.

In this article, we'll examine how to better lock down wireless applications, with a focus on cryptography. We'll start by examining applications that run on WAP networks, and their particular security concerns. WAP gateways are commonly used to mediate between the general Internet and both wireless LANs (such as 802.11 networks) and wireless WANs (such as cell phone networks). We'll then take a quick look at the more free-form P2P networks and see what security problems are there. Finally, we'll present a code example that shows how your J2ME applications can encrypt data to improve security in any network.

How to talk infosec with kids

Posted on 17 September 2014.  |  It's never too early to talk infosec with kids: you simply need the right story. In fact, as cyber professionals itís our duty to teach ALL the kids in our life about technology. If we are to make an impact, we must remember that children needed to be taught about technology on their terms.
