The correct choice is Public Key Infrastructure (PKI) technology, which serves as the backbone of the Controlled Substance Ordering System (CSOS). PKI utilizes a pair of cryptographic keys—a public key and a private key—to facilitate secure data exchange. This technology ensures the authenticity and integrity of electronic orders by encrypting the data during transmission and allowing for secure digital signatures, which helps in verifying the identity of the sender.

While blockchain technology is known for its security features in transaction systems, it is not the underlying technology used by CSOS. Similarly, Secure Socket Layer (SSL) is a protocol for establishing secure communications over a network, but it does not provide the identity verification and digital signature functionalities specific to CSOS. Two-factor authentication, while it enhances security by requiring two forms of verification, does not directly pertain to the secure exchange of data in the context of CSOS.
