    • A secure processing device having a power saving mode, which is used for built-in apparatuses, calculates a hash value of secure data that needs to be saved when switching to the power saving mode, stores the calculated hash value in a protection storage unit whose data is not lost even in the power saving mode, encrypts the secure data and stores the encrypted data in an external memory when switching to the power saving mode. When switching back to the normal power mode, the secure processing device decrypts the encrypted data, calculates a hash value of the decrypted data and compares the hash value with the hash value stored in the protection storage unit. The decrypted data is restored to the protection storage unit when the hash values are identical, but discarded together with the encrypted data stored in the external memory when the hash values are not identical.
    • 具有省电模式的安全处理装置,用于内置装置,计算切换到省电模式时需要保存的安全数据的哈希值,将计算出的散列值存储在保护存储部中, 即使在省电模式下数据也不会丢失,在切换到省电模式时,加密安全数据并将加密数据存储在外部存储器中。 当切换回正常功率模式时,安全处理装置解密加密数据,计算解密数据的散列值,并将哈希值与存储在保护存储单元中的散列值进行比较。 当哈希值相同时,解密的数据被恢复到保护存储单元,但是当哈希值不相同时,被解密的数据与存储在外部存储器中的加密数据一起被丢弃。

    • A telephoto lens system of a four-lens-group arrangement includes a negative first lens group, a positive or negative second lens group, a negative third lens group and a positive fourth lens group. The telephoto lens system of the four-lens-group arrangement is constituted by less than six lens elements in total. The positive or negative second lens group is constituted by a positive lens element and a negative lens element which are cemented to each other, in this order from the object. The positive lens element has a convex surface with a larger curvature facing toward the object. The positive or negative second lens group satisfies the following condition: 0.8
