    Abstract: A data input is divided into two segments; the second segment is also divided into groups. Bits in the first segment are used to control the application of permutation functions to bit groups in the second segment. The transformed data is assembled from the first segment and the permuted groups of the second segment. This data transformation can be applied in combination with a key derivation algorithm, a key wrapping algorithm, or an encryption algorithm to enhance the security of these other applications.

    Abstract translation: 数据输入分为两段; 第二部分也分为两组。 第一段中的位用于控制第二段中的位组的置换函数的应用。 经变换的数据从第一段和第二段的置换组组装。 该数据转换可以与密钥推导算法，密钥包装算法或加密算法结合使用，以增强这些其他应用的安全性。

    Abstract: Key derivation algorithms are disclosed. In one key derivation application, a segment of the master key is hashed. Two numbers of derived from another segment of the master key. A universal hash function, using the two numbers, is applied to the result of the hash, from which bits are selected as the derived key. In another embodiment, an encoded counter is combined with segments of the master key. The result is then hashed, from which bits are selected as the derived key.

    Abstract: A data input is divided into two segments. The second segment is raised to a power of a function of the first segment, the power being relatively prime to a function of a predefined modulus. The modulus is then applied to the result. The transformed data is assembled from the first segment and the remainder modulo the modulus. This data transformation can be applied in combination with a key derivation algorithm, a key wrapping algorithm, or an encryption algorithm to enhance the security of these other applications.
