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 ...

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 ...

Researchers affiliated with Caltech and the quantum computing startup Oratomic have published a preprint claiming that Shor’s ...

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 ...

"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 ...

The Looming Quantum Threat to Bitcoin Quantum computing is no longer confined to science fiction. As companies like Google push ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

For smaller networks on which keys can be manually defined, IKE preshared keys (PSKs) can be used. PSKs are manually defined in the IKE policy of each crypto endpoint. Once crypto and ISAKMP policies ...

The startling recent announcement that the SHA-1 hash function was not as secure as previously believed also raised interesting questions in the world of one-time password (OTP) technology, since the ...
