Fibre Systems:
The introduction of large-scale quantum computers would render almost all currently used key-exchange protocols useless. For optical fibre networks, quantum key distribution (QKD) seems to be the natural answer to this challenge, but it too has its ... CSO Online:
To gain the same level of security against a large quantum computer, the key would need to be around a million times larger (in the gigabyte range). At this size, one TLS handshake per hour would be optimistic. Traditional elliptic curve cryptography ... Hack Read:
Various stopgap mitigation solutions have been offered by the researchers on their blog and they are also offering a testing tool to be implemented on public HTTPS servers along with a Python tool for testing the flaw. “Most modern TLS connections use ...and more ... SC Magazine UK:
(The researchers also noted that TLS stacks from MatrixSSL and JSSE contained different, older vulnerabilities, but were included in the report because “we still see vulnerable hosts.”) Aside from applying vendor updates, the researchers recommend ... CSO Online:
Yet public-key cryptography protocols like Diffie-Hellman, RSA and elliptic-curve cryptography (ECC), which survive on the basis that they rely on large prime numbers that are hard to factor, are increasingly under threat. Many in industry believe they ... MakeUseOf:
... signed up to a VPN, and ... happy with the privacy it brings to your online activities. Maybe you use for safety on public Wi-Fi, or to beat region-blocking restrictions on your favorite streaming sites. But what if we told you that the VPN ... Hashed Out by The SSL Store™ (blog):
After the SSL certificate has been authenticated and the SSL handshake is complete, the browser and server exchange symmetric “session keys” that allow them to communicate securely for the duration of the visit. While these session keys are in play ... The Cipher Brief:
By forcing anyone wishing to take part to use the public key infrastructure (PKI), cryptocurrencies draw on the mathematical genius of public key encryption, first discovered in the late 1960s in secret by the GCHQ mathematicians James Ellis, Malcolm ...and more ... Forbes:
Though we may take it for granted, public-key encryption is essential to our daily lives and also serves as a staple of ... cryptocurrencies. You would not be able to send Bitcoin to another person securely without it. (Without going into too much ... PaymentsJournal:
Symmetric key ciphers like Advanced Encryption Standard (AES) use the same key for encrypting a message or file, while asymmetric ciphers like RSA use two linked keys — private and public. The public key is shared, but the private key is kept secret ...
