Cargo Cult Quantum Factoring
The Blog of Scott Aaronson If you take nothing else from this blog: quantum computers won't solve hard problems instantly by just trying all solutions in parallel. Also, next pandemic, let's approve the vaccines faster! Just days after we celebrated my wife’s 40th birthday, she came down with COVID, meaning she’s been isolating and I’ve been spending almost all my time dealing with our kids. But i
Breaking RSA with a Quantum Computer - Schneier on Security
Breaking RSA with a Quantum Computer A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm that factoring with a quantum computer is easy. But it takes a big quantum computer, on the o
自堕落な技術者の日記 : RSAとECDSA、署名生成と署名検証どっちが速い？ - livedoor Blog（ブログ）
Ruby + OpenSSLで署名 Ruby + OpenSSLでRSAやECDSA署名するには、OpenSSLコマンドで普通に PKCS#5の秘密鍵と公開鍵を準備してこんな感じで署名生成、署名検証すればヨロシ。 # ECDSAの署名生成 prvKey = OpenSSL::PKey::EC.new(File.read(PKCS#5秘密鍵PEM)) hashed = OpenSSL::Digest::SHA1.digest(署名対象メッセージ) sigVal = prvKey.dsa_sign_asn1(hashed) # ECDSAの署名検証 pubKey = OpenSSL::PKey::EC.new(File.read(PKCS#5公開鍵PEM)) hashed = OpenSSL::Digest::SHA1.digest(data) isValid = pubKey.dsa_ver
