Há 2 dias · In a groundbreaking 1976 paper, Whitfield Diffie and Martin Hellman proposed the notion of public-key (also, more generally, called asymmetric key) cryptography in which two different but mathematically related keys are used—a public key and a private key.
Há 4 dias · Asymmetric key cryptography (aka public key cryptography): Invented by Whitfield Diffie and Martin Hellman to address the key management issue of symmetric key cryptography, this concept uses two separate keys: a public one for encryption and a private one for decryption.
Há 4 dias · Beim Diffie-Hellman-Merkle-Schlüsselaustausch handelt es sich um das erste der sogenannten asymmetrischen Kryptoverfahren (auch Public-Key-Kryptoverfahren), das veröffentlicht wurde. Es löst das Schlüsseltauschproblem, indem es ermöglicht, geheime Schlüssel über nicht-geheime, also öffentliche, Kanäle zu vereinbaren.
Há 4 dias · The advent of public-key cryptography, pioneered by Whitfield Diffie and Martin Hellman in the 1970s, revolutionized the field by introducing a novel approach to key management and secure...
Há 2 dias · Paul Erdős (1913–1996) was a Hungarian mathematician. He considered mathematics to be a social activity and often collaborated on his papers, having 511 joint authors, many of whom also have their own collaborators. The Erdős number measures the "collaborative distance" between an author and Erdős.
Há 5 dias · Environment. The secret lives of plankton. Tiny plankton play a huge role in regulating natural systems, but they remain poorly understood. Stanford bioengineer Manu Prakash leads an international effort to develop innovative, low-cost tools that could help enable citizen scientists to monitor oceans and contribute to climate change solutions.
