    • An electric device 1 includes: an air inlet 3 through which air is taken in; a gas-liquid contact portion 5 for making gas-liquid contact between the air taken in and electrolyzed water 4 to purify the air; a water collecting portion 6 for collecting moisture in the air after the gas-liquid contact; an air outlet 7 through which the air the moisture in which was collected is ejected, wherein the air inlet 3, the gas-liquid contact portion 5, the water collecting portion 6, and the air outlet 7 are arranged in sequential order from upstream of an air duct 2; a water storage portion 8 in which the gas-liquid contact portion 5 is dipped and in which the water collected by the water collecting portion 6 is stored; and an electrolyzing portion 9 for generating the electrolyzed water 4 containing an active oxygen species by electrolyzing the water stored in the water storage portion 8. As a result, a compact electric device with an air cleaning function is provided at low cost that is capable of generating water containing an active oxygen species without requiring additional water feed and without generating a by-product.

    • 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.
    • 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。
