In one embodiment, the invention is a method and apparatus for designing combinational logics with resistance to hardware Trojan induced data leakage. The invention solves the untrustworthy fabrication risk problem by introducing a design method such that even when the design is entirely known to an attacker and a data leakage Trojan is injected subsequently, no useful information can be obtained. This invention contains several methods as shown in several embodiments. The methods include randomized encoding of binary logic, converting any combinational binary logic into one with randomized encoding, and partitioning a randomized encoded logic for split manufacturing.

Secure logic chip for resisting hardware trojan induced leakage in combinational logics

The invention is a secure logic chip with resistance to hardware Trojan induced data leakage. The invention solves the untrustworthy fabrication risk problem by introducing a secure logic chip design such that even when the design is entirely known to an attacker and a data leakage Trojan is injected subsequently, no useful information can be obtained. This invention contains several features including randomized encoding of binary logic, converting any combinational binary logic into one with randomized encoding, and partitioning a randomized encoded logic for split manufacturing.

Secure logic chip for resisting hardware trojan induced leakage in combinational logic

Apparatus, method and article of manufacture providing a randomized encoding scheme for sequential logics, for resistance to data leakage. Invention employs dual-rail encoding to randomize the information in the chip, and employs three-dimensional integration technology to protect the critical information that is needed to decode the data anywhere on-chip. With the present invention, even when the entire design is completely known to the attacker who also has full access to the outsourced portion, it is still not always possible to identify the information in the chip using data leakage Trojans.
