Reconfigurable processor for NIST Elliptic Curve Cryptography

ABSTRACT

Exchange of information must integrate a means of protecting data against unauthorized access.

Cryptography plays an important role in achieving information security. It is used
for
(1) encrypting or signing data at the source before transmission, and then
(2) decrypting or validating the signature of the received message at the destination. This thesis focuses on the study of the hardware implementation of a reconfigurable processor supporting elliptic curve cryptography (ECC) over prime fields GF(p).

The proposed processor can be reconfigured to work with any of the five prime fields recommended by NIST (192 to 521 bits). Our processor can be programmed to execute any sequence of basic modular operations (add, subtract, multiply, invert) used in higher level ECC arithmetic. The architecture has been prototyped on a Xilinx FPGA. Its performance is competitive with existing hardware implementation, despite the overhead needed to support datapath reconfigurations for different prime sizes.

Myafricasite now with embedded mp3 player and streaming radio

myafricasite now has a streaming radio player.
There are currently 6 african radio stations you can choose from. It plays one of them at random when it loads, but you can still select the station you want by clicking fast forward.





The stations are


1) Hitz Radio

2) Radio Palmwine (4 different stations)

3) and NaijaRadio

You can listen to nigerian and other african streaming radio stations as more stations will be added.

They also have an mp3 player to listen to all the music streamed off members profile. listen to the mp3's by clicking here

Meebo now offers embedded instant messaging as well as single sign-on to Yahoo, MSN, AOL and GMail

Meebo, a Web-based instant messaging provider, was set to unveil on Wednesday the capability for people to add instant messaging into any Web page be it a blog or social networking profile like myafricasite, myspace or hi5. In fact the popular social networking site for Africans www.myafricasite.com has embedded the meebo chat widget on all their profiles to allow other members chat with them.

One other advantage meebo has is its single-sign on for all major instant messaging networks. So you can have a unified IM profile that logs into your yahoo, msn, google talk and AOL accounts. So go to www.meebomo.com to get your embeedded chat widget and chat with vistors to your website, profile or blog
