An efficient logic obfuscating strategy for hardware security using SIC generator

The fast increment of ICs configuration has brought an historical change in the industry. An numerous attacks such as counterfeiting, reverse engineering and IP theft occurs in ICs. For the security of ICs, a logic obfuscating method is implemented. Logic obfuscation conceals the functionality by embedding extra keys into the original design. The keys embedded for the obfuscation are called key-gates. The extra gates ought to display its right performance (i.e. produces correct yields), so substantial key must be provided to the obfuscated design. Single Input Changing Generator (SICG) is utilized to produce the sequence of key values. The SICG is additionally associated with the contribution to create the info values for Built In Self-Testing (BIST testing).
