Team Captures RSA Keys With AM Radio and Cell Phone

Coil whine: it’s not just a problem for PC gaming enthusiasts anymore. A recent paper outlines an attack vector for capturing RSA keys by analyzing the noises, RF variations, or electromagnetic changes produced from computers as they do intense computational tasks. Of particular note is their work capturing RSA keys with sound. This so-called ‘coil whine’ is loud and regular enough to be picked up by a cell phone mic attached to an AM radio from as much as a foot away, or over thirty feet using more sophisticated equipment. The process takes time, isn’t stealthy, and isn’t exactly....

The Cell Phone Connected the Unbanked, Bitcoin Will Bank Them

In a guest post on Virgin Entrepreneur Dominic Frisby - the author of "Bitcoin: the Future of Money?" - argues that Bitcoin will do to banking what the cell phone did to telecom. Cell phones are technically more advanced and much more flexible than landline phones, and today they offer a lot of new and useful options, but the main reason for the explosive growth of the cell phone market worldwide is financial inclusion. "Quite simply, many people couldn't get access to the basic financial services needed to get a landline. Landlines were, except for pay-phones, credit-based. You needed a....

DOJ Tightens Requirements for Cell Site Simulators, Blockchain Offers More Transparency

Consumer privacy has been a hot topic for over a year now, and it looks like a new ruling by the Department of Justice might move things along in the right direction. Federal law enforcement agencies will be forced to be more transparent about cell-phone surveillance technology. While this decision is only a small step in the right direction, it is setting a precedent for future rulings protecting consumer privacy. Law enforcement agencies – including the DEA, FBI and US Marshals Service – will need to explain how cell-phone surveillance technology will be used when requesting a warrant.....

HamRadioCoin: Crypto via Radio, Alternative Blockchain Channel

HamRadioCoin utilizes the traditional Ham radio mesh to serve modern blockchain technology. This provides the blockchain and cryptocurrency with the first real alternative channel - a communications network that is both standardized and global. Ham radio has been in existence for over 80 years and who could have thought that its global array of operators would emerge as the perfect candidate for providing a P2P alternative to the internet. As we'll explore below, the invaluable role of Ham radio extends its utility into science fiction as the "old" radio combines with the "new" blockchain.....

BitPay's Copay Team Broadcasts First BIP32 P2SH Multisig Transaction From Argentina

There has been quite a lot of buzz surrounding multisig (multisignature) and bitcoin. But what exactly is it? Many think it's the future of bitcoin, and for a good reason. In short, multisignature transactions are unique in that they allow for more than one private key to control a wallet address. At present, most users deal with one public address, and one public. The issue with that is that it becomes incredibly easy to lose access to funds should the private key become compromised. As put by BitPay today on the BitCore blog: In a 2-of-2 multisignature transaction, a private key from....

Mycelium Entropy: Exclusive Interview

Entropy, if you don’t already know, is a new product Mycelium is making, with the help of crowdfunding via IndieGogo. Entropy claims to be the safest way to generate paper wallets by using a hardware based entropy (hence the name) to generate a wallet. For more information, check out this video that can be found on Myceliums website. It originally started as a Bitcoincard key backup. We had a radio dongle for gatewaying between internet and the bccard’s radio network. So we decided to check if it was good for making secure backups. The idea was to plug it into a printer and get a key....
