Encryption

Encryption technology has advanced to the point where it's pretty reliable.

Because of the three node nesting, no single computer in the Tor network knows either the ultimate source or destination of the traffic, or even the other computer’s encryption keys, shielding users identities.

The malware was stealing private encryption keys and private encryption certificates used to cipher connections and locally stored data.

Quantum computers might one day have the ability to push computational boundaries, allowing us to solve problems that have been intractable thus far, such as integer factorization, which is important for encryption.

The European Court of Human Rights has declared that backdoored encryption is illegal.

Fully homomorphic encryption (FHE) is a new encryption technique that enables computing on data blindly, without decrypting it.

As ZT() can only test whether a single ciphertext is an encryption of zero, it cannot work when there are more than one ciphertext to test.
