Important information regarding the recent AMS power outage.

The transformer that provides electricity to the AMS building in Providence went down on Sunday, April 22. The restoration of our email, website, AMS Bookstore and other systems is almost complete. We are currently running on a generator but overnight a new transformer should be hooked up and (fingers crossed) we should be fine by 8:00 (EDT) Wednesday morning. This issue has affected selected phones, which should be repaired by the end of today. No email was lost, although the accumulated messages are only just now being delivered so you should expect some delay.

Thanks for your patience.

"You're Secret's Safe," by Michael Brooks. New Scientist, 5 January 2002,pages 20-23.

This article discusses a new approach to encryption, developed by Harvardprofessor Michael Rabin. Rabin's method uses random bits from a data stream(or from several streams) in order to encrypt information. The method does notstore a key for the encryption, and hence the message cannot be decrypted,except by those who captured the random bits of data in the first place. Rabinsays he is developing a practical way to implement the scheme. Governmentagencies that try to keep tabs on new encryption methods will likely watch thisdevelopment, especially given the newfound emphasis on preventing terroristactivity.
