errors were intentionally injected into the mac design, to create the mac_err

benchmark. The results indicate that the actual (tree-growing) iteration count is far

less than the worst case, presented in the last column of Fig. 10.13 .

10.3 BASIC CONCEPTS OF SoC SECURITY

Having discussed verifi cation issues in the previous sections, we now focus on

the challenges associated with designing secure SoCs. The concept of informa-

tion security was fi rst explored in the context of communication systems [91].

When sensitive data is exchanged between two entities using public networks,

it is essential ...
