    Abstract: An approach to cryptographic security uses a “fuzzy” credential, in contrast to a “hard” credential, to eliminate cryptographic algorithmic repeatability on a device that may be subject to physical attacks. By eliminating repeatability performed at an algorithmic (e.g., gate or software) level, a device inherently lacks one of the fundamental setup assumptions associated with certain classes of side channel, fault injection, timing, and related attacks, thus helps to protect the system against such attacks while preserving the cryptographic security of the system.

    Abstract translation: 加密安全性的方法使用与硬凭证相反的模糊凭证来消除可能遭受物理攻击的设备上的加密算法重复性。 通过消除在算法（例如门或软件）级别执行的重复性，设备固有地缺乏与某些类别的侧信道，故障注入，定时和相关攻击相关联的基本设置假设之一，从而有助于保护系统免受 这种攻击同时保留了系统的加密安全性。

    Abstract: A method is used to reliably provision and re-generate a finite and exact sequence of bits, for use with cryptographic applications, e.g., as a key, by employing one or more challengeable Physical Unclonable Function (PUF) circuit elements. The method reverses the conventional paradigm of using public challenges to generate secret PUF responses; it exposes the response and keeps the particular challenges that generate the response secret.

    Abstract translation: 一种方法用于可靠地提供和重新生成有限和确切的比特序列，以通过采用一个或多个可挑战的物理不可克隆功能（PUF）电路元件与密码应用程序（例如密钥）一起使用。 该方法扭转了使用公共挑战产生秘密PUF响应的常规范例; 它暴露了响应，并保持产生响应秘密的特定挑战。
