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： Accelerated computation of combinations of group operations in a finite field is provided by arranging for at least one of the operands to have a relatively small bit length. In a elliptic curve group, verification that a value representative of a point R corresponds the sum of two other points uG and vG is obtained by deriving integers w,z of reduced bit length and so that v=w/z. The verification equality R=uG+vQ may then be computed as −zR+(uz mod n) G+wQ=O with z and w of reduced bit length. This is beneficial in digital signature verification where increased verification can be attained.
摘要翻译：通过将至少一个操作数布置成具有相对较小的比特长度来提供有限域中的组操作的组合的加速计算。在椭圆曲线组中，代表点R的值对应于其他两个点uG和vG的和的验证是通过导出比特长度减小的整数w，z获得的，并且使得v = w / z。然后，验证等式R = uG + vQ可以被计算为-zR +（uz mod n）G + wQ = 0，其中z和w的比特长度减小。这在数字签名验证中是有益的，其中可以实现增加的验证。

摘要： In general terms, the invention provides a finite field engine and methods for operating on elements in a finite field. The finite field engine provides finite field sub-engines suitable for any finite field size requiring a fixed number of machine words. The engine reuses these engines, along with some general purpose component or specific component providing modular reduction associated with the exact reduction (polynomial or prime) of a specific finite field. The engine has wordsized suitable code capable of adding, subtracting, multiplying, squaring, or inverting finite field elements, as long as the elements are representable in no more than the given number of words. The wordsized code produces unreduced values. Specific reduction is then applied to the unreduced value, as is suitable for the specific finite field. In this way, fast engines can be produced for many specific finite fields, without duplicating the bulk of the engine instructions (program).
