2020 arXiv   pre-print
This paper reports on the computation of a discrete logarithm in the finite field F_2^30750, breaking by a large margin the previous record, which was set in January 2014 by a computation in F_2^9234.  ...  discrete logarithm record for prime fields, set in a field of bit-length 795, and demonstrates just how much easier the problem is for this level of computational effort.  ...  Acknowledgements The authors would like to thank EPFL's Scientific IT and Application Support (SCITAS) as well as the School of Computer and Communication Sciences (IC) for providing computing resources  ...

Unleashing the power of semantic text analysis: a complex systems approach

Andrea Martini
The name bit stems from the contraction of binary digit, adopted for the first time in the Shannon’s milestone paper [183] as the basic unit of information in computing and communication theory.  ...  The only influence of the base of the logarithm is on the units of I (x i ): e.g. , if the logarithm is to the base 2, then I (x i ) is expressed in bits, where log2 12 = 1bit.  ...
