The objective of this research work was to develop a ternary based public key exchange scheme that is addressable to replace, or complement, the existing Public Key Infrastructures (PKI). The Ternary Addressable Public Key Infrastructure (TAPKI) leveraged arrays of physical unclonable functions (PUFs) and heterogeneous ternary/binary computing systems. Public, and private key pairs are binary streams while the core of the T-PKA is based on ternary logic. The communication between parties can occurs over untrusted channels, by exchanging dynamically generated public keys, and using legacy binary codes. The proposed ternary environment largely enhanced entropy, creating an additional level of cyber-protection.
