Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier.Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge).
Cryptographic attacks that subvert or exploit weaknesses in this process are known as random number generator attacks. A high quality random number generation (RNG) process is almost always required for security, and lack of quality generally provides attack vulnerabilities and so leads to lack of security, even to complete compromise, in ...
In cryptography, a block cipher is a deterministic algorithm that operates on fixed-length groups of bits, called blocks. Block ciphers are the elementary building blocks of many cryptographic protocols. They are ubiquitous in the storage and exchange of data, where such data is secured and authenticated via encryption.
Berry Schoenmakers and Andrey Sidorenko publish a Cryptanalysis of the Dual Elliptic Curve Pseudorandom Generator, showing that empirically the output from Dual_EC_DRBG can be distinguished from random bits, concluding that Dual_EC_DRBG is insecure as a CSPRNG. Note that this is a separate problem from the backdoor.
This table denotes, if a cryptography library provides the technical requisites for FIPS 140, and the status of their FIPS 140 certification (according to NIST's CMVP search, [27] modules in process list [28] and implementation under test list).
A rainbow table is a precomputed table for caching the outputs of a cryptographic hash function, usually for cracking password hashes.Passwords are typically stored not in plain text form, but as hash values.
The attacker knows ^, the generator matrix of an (,) code ^ that is combinatorially able to correct errors. The attacker may ignore the fact that C ^ {\displaystyle {\hat {C}}} is really the obfuscation of a structured code chosen from a specific family, and instead just use an algorithm for decoding with any linear code.
While /dev/urandom is still intended as a pseudorandom number generator suitable for most cryptographic purposes, the authors of the corresponding man page note that, theoretically, there may exist an as-yet-unpublished attack on the algorithm used by /dev/urandom, and that users concerned about such an attack should use /dev/random instead.
