Leveraging KVM Events to Detect Cache-Based Side Channel Attacks in a Virtualization Environment

Table 5

Comparison between clean, noisy, mimicry, and reduced probe frequency scenarios.

Scenario	(a)	(b)	(c)
Clean	44	7.8	75.93
Noisy (200 CU)	178	82.3	78.86
Mimicry R/W	209	10.5	134.22
Reduced Probing freq.	NA	NA	761.83

(a) Number of encryptions needed to create a cache line pattern of the upper 4 bits of with less than 2% error (average of 10 attempts); (b) standard deviation of (a); (c) CPU task-clock needed to find the pattern for 100 encryptions (average of 10 attempts).
