On the other hand, maybe if Switzerland becomes the "crypto-nation," its citizens and politicians will support anything related to "crypto" and deny any anti-encryption bans, too.
I'm actually starting to believe that the increasing popularity of cryptocurrencies will forever seal the fate of encryption backdoors and any such ideas from politicians/law enforcement. No one will dare to make such comments 10 years from now, if 30% of the U.S. economy will be based on encryption-using cryptocurrencies.
- bonzini 9y agoCryptocurrencies do not really use encryption for anything, do they?
- icebraining 9y agoThey use digital signatures, which involves encrypting the hash of the message (in this case, the transaction) with a private key.
- baby 9y agoI wouldn't call that encryption. It's a distinct primitive.
- icebraining 9y agoThe process is literally encryption; the distinction comes only from how that encryption is used.
- baby 9y agoIt is definitely not encryption. I believe it initially came from non-interactive zero knowledge protocols. See for example Schnorr signatures: https://cryptologie.net/article/193/schnorrs-signature-and-non-interactive-protocols/ https://cryptologie.net/article/193/schnorrs-signature-and-n...
- icebraining 9y agoThe process takes a plaintext message (c) and uses a algorithm and a private key to encode it into ciphertext (d), which is then decoded by the recipient using a public key. What definition of encryption do you use that doesn't fit this process?
- baby 9y agoIt does not encode it into a ciphertext at all. Did you read the article? You do not get back the message, actually there is no way to get back to the message with this signature.
- icebraining 9y agoIn this case, the hash is the message being encrypted. It's the (c), as I indicated in my previous post. The text being signed is not encrypted, but the signature still involves encryption.
- baby 9y agoDo you have a source that calls this encryption? Is modular multiplication what you're calling encryption? I'm really confused. Bytheway definition of encryption: https://en.wikipedia.org/wiki/Encryption https://en.wikipedia.org/wiki/Encryption
- bonzini 9y agoYeah, but everybody can decrypt it. It's a public key cryptosystem, but it's not going to help fighting against backdoors because it doesn't need one in the first place.
