A recent, yet to be proven paper claiming to have found a way to "destroy the RSA cryptosystem" has cryptographers asking what might replace it. What if a big crack appeared overnight in the ...

A digital signature, an asymmetric cryptography is designed using VHDL. The implementation has a Message Digest block and a RSA block. Implemented Digital Signature Algorithm on a Spartan 3 FPGA board ...

Hackers try to find novel ways to circumvent or under­mine data encryption schemes all the time. But at the Black Hat security conference in Las Vegas on Wednesday, Purdue University researcher Sze ...

Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

Your Email is Encrypted Today, but Will It Hold Up Tomorrow? Awakening one day to discover that every “secure email” you’ve ever written was not secure at all. Your client contracts, financial ...

"For this reason, we will be disabling the "ssh-rsa" public key signature algorithm by default in a near-future release." I'm confused, does this mean public-private key passwordless authentication ...
