The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a ...

In the realm of secure communications, data exchange and secret key agreement algorithms are pivotal for establishing confidentiality and ensuring the integrity of information transmitted over ...

Host Identity Protocol, or HIP, is a layer 3.5 solution and was initially designed to split the dual role of the IP address - locator and identifier. Using HIP protocol one can solve not only mobility ...

Researchers have devised a way to place undetectable backdoors in the cryptographic keys that protect websites, virtual private networks, and Internet servers. The feat allows hackers to passively ...

In my previous article/video how does encryption work? I wrote about the principles of encryption starting with the Caesar cipher and following the development of cryptography through to the modern ...

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 ...

Researchers have uncovered a flaw in the way that some servers handle the Diffie-Hellman key exchange, a bug that’s somewhat similar to the FREAK attack and threatens the security of many Web and mail ...

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 ...
