A stream cipher is an encryption method in which data is encrypted one byte at a time. In this method, a cryptographic key and algorithm are applied to each binary digit in a plaintext data stream to ...

Stream ciphers are symmetric key encrypting algorithms that work on single bits of the plaintext (Figure 2.7). While they are similar to the one-time pad, instead of XORing the message to a pure ...

Fumio Futami at Tamagawa University, Quantum ICT Research Institute, announced the world first transmission of the stream cipher by Yuen 2000 protocol (Y-00) at the bit rate of 40 Gbit/sec over 120 km ...

How do we know if the electronic keys we use in our devices are really secure? While it is possible to rigorously test the strength of a cipher—a kind of digital data lock—there are rarely any ...

Immediate algorithms on quantum computers could effortlessly decipher numerous cryptosystems, requiring more ingenious resolutions for security in a digital world. Scientists at Ritsumeikan University ...

Cryptography is something of a cryptic field, if you’ll forgive the pun. While one researcher erects the walls of a new technique, another tries to smash it to pieces. Seemingly counterintuitive, near ...

It’s been more than 25 years since Ron Rivest invented his RC4 stream cipher, and after all that time it’s still being used widely, which is something of an achievement in the crypto world. However, ...

The total amount of money invested in the project. The total cost includes EU contribution as well as other project costs not covered by EU funding. It is expressed in euros. Amount of money, by way ...
