Over 10 years ago, Satoshi Nakamoto wrote a classic white paper on Bitcoin, and the rest is history:

I have been reading an excellent paper [1] and it outlines the usage of the fault attack on ECDSA signatures. With this we just need one good signature and a bad one, and where they both a sign the same message, and with the same nonce, and the same private…

TLS is truly one of the worst and the best protocols. When it works well, it protects data like no other method, but its implementation has often been buggy, and it copes with so many options. One of its greatest weaknesses is that Eve can select the weakest cipher suite…

All those charts that show you how long it will take to crack a hashed version of a password are defined wrong. Most will take the cracking speed of a fast hashing method and use that. With a proper KDF (Key Derivation Function), we normally slow down the whole process…

RSA is used in many areas of cybersecurity and is often key in proving the identity of a person or a remote Web site. But, the strength of RSA depends on the prime numbers (p and q) selected to provide the modulus (n=p.q). If there are weaknesses in the selection…

In 1990, Michael Wiener defined a crack on RSA which involved a short decryption exponent and which used continued fractions [1]:
