摘要： The present invention provides a password recovery system that re-supplies a password to only the legitimate user of the password. The password recovery system includes a memory card with CPU and a mobile phone. When a password needs to be recovered, a phone call is made, to the mobile phone, from a telephone connected to a phone line whose phone number is registered in advance into the memory card with CPU. The mobile phone then obtains the telephone number of the phone line via a caller's telephone number notifying service. It is judged whether the obtained telephone number and the registered phone number are the same, and when they are the same, the password stored in the memory card with CPU will be re-supplied so that the user can recover it.

摘要： The present invention provides an encryption apparatus that prevents plaintext data from leaking even if accumulated data is analyzed, while preventing the size of encrypted data from increasing. An encryption apparatus for encrypting a data piece that is smaller than a unit length for encryption performs the following: storing management information indicating a used area within an encryption area defined based on the unit length, the used area being an area already used for encryption; when encrypting a new data piece that is smaller than the unit length, generating encrypted data by adding the new data piece to an unused area within the encryption area with reference to the management information, the unused area being an area not used for encryption; and updating the management information to include an area for the new data piece into the used area, after generating the encrypted data.

摘要： In a content-log analyzing system, content includes additional information indicating, according to a property of the content, whether or not to record communication of the content in a content-log. When transmitting content to a TV or a PC, a data-communication controlling device judges whether or not to record the communication in a content-log based upon additional information of the content, and when judging affirmatively, generates and stores content-log information. A content-log analyzing server obtains the content-log stored in the data-communication controlling device, and analyzes the obtained content-log.

摘要： Resistance against simple power analysis is maintained while a smaller table is used. An IC card 100 decrypts encrypted information using elliptic curve calculation for calculating a point k*C by multiplying a point C on the elliptic curve E with a coefficient k that is a positive integer less that a prime p. The calculation of the point k*C is performed by adding a multiplication result obtained by multiplying a digit position (window) value w of the acquired coefficient k with the point C in a position corresponding to the digit position, and is performed with respect to all digit positions. When a non-negative integer exists that fulfills a condition that the acquired digit value w can be divided by 2t and cannot be divided by 2t+1, the multiplication includes adding a point obtained by multiplying a point Q with w/2t.

摘要： In an authentication system, a key registration apparatus receives input of an identifier unique to a second device, generates first key data from the identifier according to a predetermined key generation algorithm, and transmits the generated first key data to a first device, which receives and stores the first key data, and authenticates the second device with use of the first key data. The second device stores in advance second key data generated from the identifier according to the predetermined key generation algorithm, and is authenticated by the first device with use of the second key data. Accordingly, the first and second devices cannot be registered without using the key registration apparatus, thereby preventing communication with unregistered devices. This enables usage of content to be limited to individual usage in the home of a user, and can be realized even with devices that are not connected outside the home.
摘要翻译：在认证系统中，密钥注册装置接收对第二装置唯一的标识符的输入，根据预定的密钥生成算法从标识符生成第一密钥数据，并将生成的第一密钥数据发送到第一装置，存储第一密钥数据，并使用第一密钥数据认证第二设备。第二设备预先存储根据预定密钥生成算法从标识符生成的第二密钥数据，并且通过第二密钥数据由第一设备认证。因此，在不使用密钥登记装置的情况下，不能登记第一和第二装置，从而防止与未登记装置的通信。这使得内容的使用被限制在用户的家庭中的个人使用，并且即使使用不在家外的设备也可以实现。

摘要： An RSA decryption apparatus that is used in an IC card or the like counters a differential fault attack. The RSA decryption apparatus computes at high speed a public key used in data verification, without having to obtain the public key from an external source. The RSA decryption apparatus includes a remainder computation unit 412 that calculates dp=d mod (p−1), and an inverse computation unit 414 that finds an inverse of dp over a residue field with p−1 as a modulus. The RSA decryption apparatus verifies a decipher text with use of the inverse of dp as the public key. The reduced bit count in inverse computation compared to if the inverse of d is found as the public key increases computing speed.
