    摘要: Systems and methods of oracle authentication in a network using a plurality of memory physical unclonable functions (PUFs). Method starts with oracle receiving initialization vector including initial seed value from client device. Oracle generates template that includes a PUF array. Oracle computes template using a superset of combinations of PUFs included in the oracle and transmits template to client device. Oracle generates first seed value, first key, and first authentication nonce, using pseudorandom number generator and the initial seed value. When oracle has first data to be sent to the client device, oracle generates first token using PUF array and first authentication nonce. Oracle generates first message by encrypting first data and first token using first key. The oracle transmits first message to the client device. Other embodiments are also disclosed.
