Bias Variation Compensation in Perimeter-Gated SPAD TRNGs

Random number generators that utilize arrays of entropy source elements suffer from bias variation BV. Despite the availability of efficient debiasing algorithms, optimized implementations of hardware friendly options depend on the bit bias in the raw bit streams and cannot accommodate a wide BV...

40th anniversary of the computer virus !

This year marks the 40th anniversary of Creeper, the world's first computer virus. From Creeper to Stuxnet, the last four decades saw the number of malware instances boom from 1,300 in 1990, to 50,000 in 2000, to over 200 million in 2010. Besides sheer quantity, viruses, which were originally use...
