A method of encrypting unencrypted digital content includes measuring an analog value associated with a physical property of interested cells of a memory array; digitizing the measured analog value to generate a response key; generating an encryption key based at least on the response key; encrypting the unencrypted digital content to generated encrypted digital content based on the encryption key; and storing the encrypted digital content.

Device bound encrypted data

A method generating a cryptographic key and corresponding helper data includes measuring an analog value associated with a physical property of cells of a memory array; digitizing the measured analog value to generate the cryptographic key; quantizing the measured analog value to generate the corresponding non-leaky helper data.

Non-leaky helper data: extracting unique cryptographic key from noisy F-PUF fingerprint

A method for protecting encoded data from algebraic manipulation includes receiving a data word s&#x3b5;Kto be protected, randomly selecting two integers a &#x3b5;{0, . . . , q&#x2212;1} and b &#x3b5;{0, . . . , &#x221a;q&#x2212;1}, finding a point (&#x3b1;, &#x3b2;) on a Hermitian curve over a field Fthat corresponds to the randomly selected integers (a, b) from a mapping (a, b)(&#x3b1;, &#x3b2;)=(u, uz+v), where and z is an element of the field Fof unit trace, and where &#x3b3;is a fixed primitive element of the field Fand &#x3b3;is a primitive element of a field FF, and calculating a sum f(&#x3b1;, &#x3b2;)=&#x3b1;&#x3b2;+&#x3a3;&#x3b1;&#x3b2;kfor a set of d+1 integers pairs I ={(i,j)}, where the encoded word is a triple (s, (&#x3b1;, &#x3b2;),f(&#x3b1;, &#x3b2;)).
