摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable media for authentication using a shared table. The method receives an authentication challenge from a first entity including an accumulator with an initial value, lists of elements in a shared table, and a list of sorting algorithms, each sorting algorithm is associated with one of the lists of elements and modified to include embedded instructions operating on the accumulator. The method then generates a temporary table for each list of elements in the shared table by copying elements from the shared table as indicated in each respective list of elements, each temporary table being associated with one sorting algorithm in the list of sorting algorithms. The method sorts each generated temporary table with the associated sorting algorithm, thereby updating the accumulator with the embedded instructions. Finally, the method transmits the updated accumulator to the first entity for verification.

摘要： Computers and other electronic devices typically include a timing operation such as a clock in an operating system. It is anticipated that hackers may tamper with this clock. This tampering might be especially advantage in the context of systems which provide for rental of audio and video content, such as movies. Tampering with the system clock on the playing device would allow an extension of the rental period to the detriment of the provider of the rental content. Hence the present method is directed to detecting clock modifications both in terms of time shifting and clock rate tampering. This detection is done using digital signal processing.

摘要： In the field of computer software (code) security, it is known to include verification data such as hash values in or associated with the code to allow subsequent detection of tampering by a attacker with the code. This verification technique is used here in a “White Box” cryptographic process by tying the verification data to the content of functional table lookups present in the object (compiled) code, where values in the table lookups are selectively masked (prior to the source code being compiled into the subject code) by being subject to permutation operations.

摘要： In the field of computer and data security, the identifier (ID) of a computing device is protected by providing a secure signature used to verify the ID. The signature is computed from the ID using a “White Box” cryptographic process and a hash function. This provides a signature that is computationally easy to verify but difficult or impossible to generate by a hacker (unauthorized user). This method of first creating the signature and later verifying the identifier using the signature and the associated computing apparatus are thereby useful for protection against hacking of such identifiers of computing devices.

The input may correspond to a result of a combination operation on the elements. Cryptographic operations may be performed on the input data and the elements to generate a plurality of data elements without providing data correlated with the key. The combination operation may be performed on the data elements for the output data.

摘要： Method and apparatus for increasing security of a cryptographic algorithm such as deciphering, enciphering, or a digital signature using a block type cipher such as AES implemented for instance in a “whitebox” model with the cipher key either known or unknown at the compilation time. This method is secure for use in entrusted environments, particularly for securing cryptographic keys. The look up tables characteristic of such algorithms are protected against attack here by making all such tables of the same size and indistinguishable, and further by masking the output values of such tables, typically where the tables carry out a permutation function or a logical exclusive OR operation.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating a hash based on the Collatz conjecture. The Collatz conjecture is based on a set of operations for a given number n that are performed iteratively on n, with one operation performed if n is even, and another operation performed if n is odd. Operating on an input value according to the Collatz conjecture for a specified number of iterations produces an output value that can then be used as a hash in a cryptographic function. The hash function performs steps according to the Collatz conjecture, or a modification thereof, on the value n for r iterations, and outputs a resulting hash value. The hash function can apply more complex variations, such as adding multiplication, addition, modulo or other operation(s) in the even and/or odd operations. The hash value can be used to pad blocks of a message.
摘要翻译：本文公开了用于基于Collatz推测来生成散列的系统，方法和非暂时的计算机可读存储介质。 Collatz猜想基于对n进行迭代执行的给定数量n的一组操作，如果n是偶数，则执行一个操作，并且如果n是奇数则执行另一个操作。对于指定数量的迭代，根据Collatz推测对输入值进行操作会产生一个输出值，然后可以将其用作加密函数中的散列。散列函数根据Collatz推测或其修改对r值的n值执行步骤，并输出所得到的散列值。散列函数可以应用更复杂的变化，例如在偶数和/或奇数运算中添加乘法，加法，模或其他操作。哈希值可以用于填充消息块。

摘要： Disclosed herein are methods for obfuscating data on a client, on a server, and on a client and a server. The method on a client device includes receiving input data, storing an operation value in a secure location, performing a modulus obfuscation on the operation value, performing a modulus operation on the operation value and the input data, performing a modulus transformation on the operation value and the input data to obtain client output data, and checking if the client output data matches corresponding server output data. The method on a server device includes receiving input data, performing a modulus transformation on the input data to obtain a result, performing a plain operation on the result and an operation value to obtain server output data, and checking if the server output data matches corresponding client output data from a client device that (1) receives input data, (2) stores an operation value in a secure location, (3) performs a modulus obfuscation on the operation value, (4) performs a modulus operation on the operation value and the input data, and (5) performs a modulus transformation on the operation value and the input data to obtain client output data. In an optional step applicable to both clients and servers, the method further includes authenticating the client input data and the server input data if the server output data matches the client output data. In one aspect, server input data and client input data pertain to a cryptographic key.
