FF (a, b, c, d, M 12 , 7, 0x6b901122) FF (d, a, b, c, M 13 Those constants, t i , were chosen as follows: In step i, t i is the integer part of 2 32 *abs(sin(i)), where i is in radians.  ...  After all of this, a, b, c, and d are added to A, B, C, D, respectively, and the algorithm continues with the next block of data. The final output is the concatenation of A, B, C, and D.  ...  DES is a symmetric algorithm: The same algorithm and key are used for both encryption and decryption (except for minor differences in the key schedule). The key length is 56 bits.  ...

HyperDegrade: From GHz to MHz Effective CPU Frequencies [article]

Alejandro Cabrera Aldaya, Billy Bob Brumley
2021 arXiv   pre-print
In addition to the new technique, we investigate the root causes of performance degradation using cache eviction, discovering a previously unknown slowdown origin.  ...  Using HyperDegrade, we developed an end-to-end attack that shows how a Raccoon-like attack can succeed with real data, filling a missing gap from previous research.  ...  In general, our off-the-shelf applied lattice techniques in Section 6.3, while serving their purpose for proof-of-concept, are likely not optimal.  ...
