DEMODAY

DEMODAY, 2017, CounterParty Tokens.

DEMODAY is the first art show-specific crypto token.

It has been created for the show “Demo Day” at Kunstraum LLC, Brooklyn, from September 24 – October 28 2017. See here for details

Robert Shore’s excellent new book about artistic originality and appropriation art contains an installation image of my “Shareable Readymades” (models by Chris Webber & Bassam Kurdali, title by Charlotte Frost) at the 2016 show “Jerwood Encounters: Common Property”.

My lasting interest in art comes in no small part from endlessly re-reading a large Andy Warhol catalogue in art class at school. When I went to art school the indebtedness of art to its past and the creative potential of appropriation art and sampling made perfect sense to me. So “Beg, Steal & Borrow”‘s canon of art that follows Steve Job’s maxim about great artists is one I love and that I’m very pleased to see the Shareable Readymades in.

Trusted Third Party Hardware

From the point of view of the Bitcoin white paper, trusted platform modules, programmable secure elements, and secure enclaves are all examples of the presence of trusted third parties. They are “Treacherous Computing” hardware that someone other than you ultimately controls, and who you must trust to act in your best interests.

If it was the case that the use of hardware that obeys trusted thirds parties in order to improve the security or speed of cryptocurrencies offered obvious benefits that cannot be achieved in any other way then objecting to this on ideological grounds might seem like an example of Emerson’s maxim that “a foolish consistency is the hobgoblin of little minds”. But trusted third party hardware is not necessarily always more secure and trustworthy than hardware or software that the user controls.

Promoting trusted third party hardware solutions in cryptocurrency without acknowledging this should therefore be questioned both ideologically and pragmatically.

Ideologically because the CEO of a hardware wallet company should not have more control of the systems that you use to hold your cryptocurrency than you do, and they should not be beholden to their chip vendor for that power either.

Pragmatically because adding more places for malware to infect and hide in, and in ways that may be impossible to detect and remove, does not make things more secure.

Given all this it is important to look beyond the marketing of trusted third party hardware. Here are some articles describing issues with such systems.

Secure Elements

Government agencies do pressure chip producers to include backdoors to their products, so why should one suppose it would be different with SE, especially knowing that these are being used for financial transactions? The user would never learn about this, because of the nature of the SE.

Is “Banking-grade Security” Good Enough for Your Bitcoins?

A team of security engineers from Rapid7 at Black Hat USA 2016 conference in Las Vegas demonstrated how a small and simple modifications to equipment would be enough for attackers to bypass the Chip-and-PIN protections and enable unauthorized transactions.

The Infineon Bug

A crippling flaw in a widely used code library has fatally undermined the security of millions of encryption keys used in some of the highest-stakes settings, including national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers.

Millions of high-security crypto keys crippled by newly discovered flaw

A vulnerability was identified in the RSA key generation method used by Trusted Platform Modules (TPMs) manufactured by Infineon and contained in some Lenovo products. RSA public keys generated by the Infineon TPM for use by certain software programs should be considered insecure.

RSA Keys Generated by Infineon TPMs are Insecure

Of course, if Infineon made this mistake, who else could have made a similar faux pas?

Secure Enclaves

Researchers have demonstrated using Intel’s Software Guard Extensions to hide malware and steal cryptographic keys from inside SGX’s protected enclave

Using Intel’s SGX to Attack Itself

It’s still too early to know what the full fallout from the SEP’s decryption will be, but it could open the door for password harvesting, spoofing, and other security-compromising attacks.

iOS users beware: A hacker has just published a decryption key for the Apple Secure Enclave, which is responsible for processing Touch ID transactions.

I have two pieces in the book.

“Bad Shibe” is the story of a young person in a post-fiat-currency utopia suffering from their first pangs of doubt that they, and more generally the society that they live in, may not be as wonderful as they previously thought. It is accompanied by Lina Theodorou’s wonderful illustrations of a story that the narrator makes very difficult to illustrate.

“Blockchain Poetics” is an essay about what proponents and critics of cryptocurrency think it is about, the historical context of these views, and how they are expressed culturally and rhetorically. It discusses trust, hodling, anti-politics, the nature of truth, and the “doge” subculture that is a major feature of “Bad Shibe.

The book is a wonderful physical artefact and the writing presents a wide range of voices, see the LUP page for details.
