In computing, bit flipping may refer to: Bit manipulation , algorithmic manipulation of binary digits (bits) Bitwise operation NOT , performing logical negation to a single bit, or each of several bits, switching state 0 to 1, and vice versa
Stream ciphers, such as RC4, are vulnerable to a bit-flipping attack, as are some block cipher modes of operation. See stream cipher attack . A keyed message authentication code , digital signature , or other authentication mechanism allows the recipient to detect if any bits were flipped in transit.
The paper found up to 3,434 incorrect requests per day due to bit-flip changes for various common domains. Many of these bit-flips would probably be attributable to hardware problems, but some could be attributed to alpha particles. [1] These bit-flip errors may be taken advantage of by malicious actors in the form of bitsquatting.
Bitsquatting is a form of cybersquatting which relies on bit-flip errors that occur during the process of making a DNS request. These bit-flips may occur due to factors such as faulty hardware or cosmic rays.
The effect of a checksum algorithm that yields an n-bit checksum is to map each m-bit message to a corner of a larger hypercube, with dimension m + n. The 2 m + n corners of this hypercube represent all possible received messages. The valid received messages (those that have the correct checksum) comprise a smaller set, with only 2 m corners.
Bit twiddling, bit fiddling, bit bashing, and bit gymnastics are often used interchangeably with bit manipulation, but sometimes exclusively refer to clever or non-obvious ways or uses of bit manipulation, or tedious or challenging low-level device control data manipulation tasks.
An asynchronous (ripple) counter is a "chain" of toggle (T) flip-flops in which the least-significant flip-flop (bit 0) is clocked by an external signal (the counter input clock), and all other flip-flops are clocked by the output of the nearest, less significant flip-flop (e.g., bit 0 clocks the bit 1 flip-flop, bit 1 clocks the bit 2 flip ...
3-Qubit-Bit-Flip Code: the first two gates encode the state in the logical subspace, the last three decode it. In between single bit-flip errors can be corrected. Items portrayed in this file
