摘要： A signature scheme is provided in which a message is divided in to a first portion which is hidden and is recovered during verification, and a second portion which is visible and is required as input to the verification algorithm. A first signature component is generated by encrypting the first portion alone. An intermediate component is formed by combining the first component and the visible portion and cryptographically hashing them. A second signature component is then formed using the intermediate component and the signature comprises the first and second components with the visible portion. A verification of the signature combines a first component derived only from the hidden portion of the message with the visible portion and produces a hash of the combination. The computed hash is used together with publicly available information to generate a bit string corresponding to the hidden portion. If the required redundancy is present the signature is accepted and the message reconstructed from the recovered bit string and the visible portion.

摘要： A system and method configured for applying Montgomery style reduction directly to negative quantities as well as positive values, producing the new form which does not require conditional operations to move values into the positive range. The low-order components of the resulting product, or partially completed product, can be reduced either by the addition of multiples of the modulus, as is usual in the standard Montgomery multiplication which accepts positive values, or by subtracting multiples of the modulus, which of course depends on the actual computation. Signed versions of the Montgomery values in a Montgomery computation are used to avoid the conditional addition and subtraction that can leak information, for example, using a two's complement representation.

摘要： A method of inhibiting the disclosure of confidential information through power analysis attacks on processors in cryptographic systems. The method masks a cryptographic operation using a generator G. A secret value, which may be combined with the generator G to form a secret generator is generated. The secret value is divided into a plurality of parts. A random value is generated for association with the plurality of parts. Each of the plurality of parts is combined with the random value to derive a plurality of new values such that the new values when combined are equivalent to the secret value. Each of the new values is used in the cryptographic operation, thereby using the secret generator in place of the generator G in the cryptographic operation. The introduction of randomness facilitates the introduction of noise into algorithms used by cryptographic systems so as to mask the secret value and provide protection against power analysis attacks.

摘要： A nozzle assembly (3, 20) with a re-useable break off cap (20) for dispensing a product from a container (1). On a dispensing end (5) of the nozzle (3) a break-off cap (20) is integrally formed thereon and closes off the dispensing end (5) of the nozzle (3). The break-off cap (20) is removable by breaking a frangible connection (22) between the nozzle (3) and the break-off cap (20). Removing the break-off cap opens the dispensing end (5) of the nozzle (3) thereby allowing product to be dispensed through the nozzle (3). The break-off cap (20) removed from the nozzle (3) can then be re-engaged with the nozzle (3) to close off the dispensing end (5) thereby preventing further product from being dispensed. The cap can be attached to or removed from the nozzle (3) as often as a user requires. Packaging which includes a tray (111) or pouch into which the nozzle assembly (3, 20) and container (1) can be inserted. A flexible resealable peel-off cover (110) is provided on each tray (111) to allow a user to resealably open and close the tray (111). The resealable tray (111) can be provided either singly or as a series of trays. The nozzle assembly may also incorporate an applicator for application of the dispensed product.
摘要翻译：一种具有用于从容器（1）分配产品的可重复使用的分离盖（20）的喷嘴组件（3,20）。在喷嘴（3）的分配端（5）上，一个整体地形成有一个断开盖（20）并封闭喷嘴（3）的分配端（5）。通过断开喷嘴（3）和断开盖（20）之间的易碎连接（22），分离盖（20）可移除。拆卸断开盖打开喷嘴（3）的分配端（5），从而允许通过喷嘴（3）分配产品。然后可以从喷嘴（3）移除的分离盖（20）与喷嘴（3）重新接合，以便关闭分配端（5），从而防止进一步的产品被分配。盖可以按照使用者的要求经常连接到喷嘴（3）上或从喷嘴（3）移除。包括其中可以插入喷嘴组件（3,20）和容器（1）的托盘（111）或小袋。在每个托盘（111）上设置柔性的可重新密封的剥离盖（110），以允许使用者可再密封地打开和关闭托盘（111）。可重新密封的托盘（111）可以单独提供或作为一系列托盘提供。喷嘴组件还可以包括用于施加分配产品的施加器。
