    摘要： In initial generation (for example, shipping from the factory), a security device generates an identifier w specific to the security device, with the PUF technology, generates key information k (k=HF(k)) from the identifier w, generates encrypted confidential information x by encrypting (x=Enc(mk, k)) confidential information mk with the key information k, and stores the encrypted confidential information x and an authentication code h (h=HF′(k)) of the key information k, in a nonvolatile memory. In operation, the security device generates the identifier w with the PUF technology, generates the key information k from the identifier w, and decrypts the encrypted confidential information x with the key information k. At a timing where the identifier w is generated in the operation, the security device checks whether the current operating environment has largely changed from the initial generation (S311). If a change in operating environment is detected (S311→S312), the security device conducts a reset-up process (S312 to S315) of an authentication code h which is confidential information, and the encrypted confidential information x.

    摘要翻译： 在初始阶段（例如，出厂时），安全设备生成特定于安全设备的标识符w，利用PUF技术，从标识符w生成密钥信息k（k = HF（k）），生成加密 机密信息x通过用密钥信息k加密（x = Enc（mk，k））机密信息mk，并且将加密的机密信息x和密钥信息k的认证码h（h = HF'（k））存储 ，在非易失性存储器中。 在操作中，安全设备利用PUF技术生成标识符w，从标识符w生成密钥信息k，并用密钥信息k对加密的机密信息进行解密。 在操作中生成标识符w的定时，安全装置检查当前的操作环境是否从初始生成发生了很大的变化（S311）。 如果检测到操作环境发生变化（S311→S312），则安全装置进行作为机密信息的认证码h的复位处理（S312〜S315）和加密的机密信息x。

    摘要： A charge controller includes a charge control circuit that, when detecting that a charging power supply is connected, controls the charging transistor to apply the charge current; a first and second control switch element connected in series between one terminal of a secondary battery and an external terminal; and a protection circuit that, when the secondary battery is over-discharged, turns off the first control switch element to stop discharge current and when deeply discharged, turns off the second control switch element. The protection circuit sends a charge inhibit signal to the charge control circuit when the secondary battery is deeply discharged, and while receiving the charge inhibit signal, the charge control circuit keeps the charging transistor off to prevent the charge current from flowing even if detecting that the charging power supply is connected.
