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 ...

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 ...

A couple of days ago on The Conversation, I set myself up with a task: to defend the usefulness of so-called “useless” maths. Today, that defence continues, with a look at the RSA algorithm. I ...

Amidst all of the confusion and concern over an encryption algorithm that may contain an NSA backdoor, RSA Security released an advisory to developer customers today noting that the algorithm is the ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

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 ...

Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and ...

"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 ...

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 ...
