Abstract
An apparatus includes an interface and logic circuitry. The interface is configured to communicate over a communication link. The logic circuitry is configured to convert between a first stream of plaintext bits and a second stream of ciphered bits that are exchanged over the communication link, by applying a cascade of a stream ciphering operation and a mixing operation that cryptographically maps input bits to output bits.
Claims18
An apparatus comprising:
- an interface, which is configured to communicate over a communication link;
- and
- logic circuitry, which is configured to convert between a first stream of plaintext bits and a second stream of ciphered bits that are exchanged over the communication link, by applying a cascade of a stream ciphering operation and a mixing operation that cryptographically maps input bits to output bits.
A method comprising:
- exchanging ciphered bits over a communication link;
- and
- converting between a first stream of plaintext bits and a second stream of the ciphered bits that are exchanged over the communication link, by applying a cascade of a stream ciphering operation and a mixing operation that cryptographically maps input bits to output bits.
