摘要： A method and system for encrypting and verifying the integrity of a message using a three-phase encryption process is provided. A source having a secret master key that is shared with a target receives the message and generates a random number. The source then generates: a first set of intermediate values from the message and the random number; a second set of intermediate values from the first set of values; and a cipher text from the second set of values. At the three phases, the values are generated using the encryption function of a block cipher encryption/decryption algorithm. The random number and the cipher text are transmitted to the target, which decrypts the cipher text by reversing the encryption process. The target verifies the integrity of the message by comparing the received random number with the random number extracted from the decrypted cipher text.

摘要： A method, is provided for efficiently determining an inverse multiplicative modulo. In many public-key cryptographic algorithms, an inverse modulo is usually calculated in key generation. However, because many Reduced Instruction Set Computer (RISC) processors do not have the hardware support for division, good results are often not yielded. Therefore, to efficiently calculate hail an inverse modulo, a modified algorithm that utilizes a minimum of three division and two multiplications in conjunction with shifts and addition/subtractions is employed. The modified algorithm then is able to efficiently utilize the properties of the RISC processors to yield good results, especially when developing keys for public-key cryptographic algorithms.

摘要： A technique for tracking one or more thresholds relating to the blocking of a particular screen name used on an IM system is disclosed. If the number of people who have blocked a particular screen name reaches a threshold amount, a determination is made that the screen name is being used by a spimmer or other bothersome person, and disciplinary action can be taken. In a preferred embodiment, the email address associated with a user name of a suspected spimmer is identified and all screen names associated with that email address are also subjected to disciplinary action, if desired. Thus, an IM company can suspend all screen names of a spimmer that are tied to the same email address, even though not all (or even none) of the screen names individually have reached a threshold level for discipline/suspension.
摘要翻译：公开了一种用于跟踪与在IM系统上使用的特定屏幕名称的阻塞相关的一个或多个阈值的技术。如果阻止特定屏幕名称的人数达到阈值数量，则确定屏幕名称正被微笑者或其他麻烦的人使用，并且可以采取纪律处分。在优选实施例中，如果需要，识别与疑似微分器的用户名相关联的电子邮件地址，并且与该电子邮件地址相关联的所有屏幕名称也受到纪律处分。因此，即使不是所有（甚至没有）屏幕名称的个人都已达到纪律/暂停的阈值水平，因此IM公司可以暂停连接到相同电子邮件地址的所有屏幕快照的屏幕名称。
