Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

Scientists at Northwestern University say they have harnessed the properties of light to encrypt information into code that can be cracked only one way: by breaking the physical laws of nature. This ...

In the context of cryptography, the un-transformed message is known as plaintext, the transformation is known as encryption and the transformed message is known as ciphertext. The encryption process ...

The threat of quantum computing being able to crack encryption methods currently used to protect critical data is being exploited by unscrupulous security suppliers, a cryptographic expert has warned.

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 ...
