Please join us this Sunday for a workshop on mobile SMS (text message)
encryption.

The number of mobile phone users is expected to exceed the 4 billion
mark by the end of this year – that’s more than two thirds of the
world’s population. And the number of text messages is expected to reach
a whopping 1.8 trillion in 2010. From the U.S. to Moldova to Iran to
Uganda cell phones have facilitated all kinds of activism. While mobile
phones bring many benefits to social movements, it is important to be
aware of the digital data trails they leave behind.

This workshop has two parts:

First, a general introduction: why encrypt your SMS? Oli from CryptoSMS,
based in Hamburg, will discuss the open-source project’s history and
current state.

Second, you’ll have a chance to get your inner hacker on with a hands-on
workshop. We’ll install the encryption software on our cell phones,
initialize them, exchange keys, and send encrypted SMS messages.

Sunday, August 23rd, 12 – 2 pm (free)

About CryptoSMS
CryptoSMS.org is a GPL (general public license) open source application
for cell phones running J2ME (Java for mobiles). It runs on a lot of
phones. CryptoSMS provides public/private key encryption, key generation
and key management. It sends and receives encrypted SMS and public keys,
encrypts and de-encrypts files, offers key verification via fingerprints
and provides a secure login.

CryptoSMS is based on encryption with elliptic curves, which is a modern
solution for encryption with small and/or embedded devices. Elliptic
curve encryption provides good performance and has low memory
requirements. It encrypts only the contents of the messages, but does
not in any way encrypt or scramble the identities of the sender or
recipients. It is not an anonymizer — it does not hide the device’s
id/number from where the SMS comes and where it goes to.

About the presenter
Oli has been involved with the CryptoSMS.org project since its
inception, and mainly keeps the project organized, does the
communication work and strongly enforces the support of many languages
in the CryptoSMS.org user interface. At the moment he is traveling to a
couple of global cities to conduct research on mobile media and
dataveillance, interviewing participants in social movements, hackers
and artists about their use of mobile media. He is based in Hamburg,
where he suffers from bad weather but enjoys people and culture.
