摘要： In computer based data security systems which involve entity authenticating or document time stamping or other cases where data is to be derived from a previous state, the necessary linking values are calculated using recursive chaos based equations such as the type used in fractal theory (the Mandelbrot set) or the Lorentz attractor or other similar approaches. In each case a value in each step is calculated using these equations so that each authentication or timestamp or other data derivation is linked to the previous one in a chaotic way. This makes it impossible to calculate any one value in the link series without having the previous value, due to the chaos aspect thereby enhancing security.

摘要： Method and apparatus for increasing security of a cryptographic algorithm such as deciphering, enciphering, or a digital signature. A cryptographic algorithm and a key are provided such that a deciphering process, for instance, is partitioned between two portions. The portion of the cryptographic algorithm carried out in the first portion is implemented in a “white box” model such that it is highly secure even against an attack by the user who has full access to internal operations, code execution and memory of the user device, such as a hacker or attacker. The remaining portion of the algorithm is carried out in the second portion. Since this second portion has relaxed security constraints, its code may be implemented using a “black box” approach where its code execution may be more efficient and faster, not requiring the code obfuscation of the white box implementation in the user device. This partitioning may be achieved using a delegation protocol. The chief advantage is that even given a limited code size for the cryptographic process, the security of the system is improved by carrying out the more computationally intensive functions more efficiently in the black box portion and executing the less computationally intensive function in the white box portion.
摘要翻译：用于提高加密算法的安全性的方法和装置，例如解密，加密或数字签名。提供了一种加密算法和密钥，使得例如在两部分之间进行解密处理。在第一部分中执行的加密算法的部分被实现在“白盒”模型中，使得即使对于完全访问内部操作，代码执行和用户设备的存储器的用户的攻击也是非常安全的，如黑客或攻击者。算法的剩余部分在第二部分中进行。由于该第二部分具有放松的安全约束，因此其代码可以使用“黑箱”方法来实现，其中其代码执行可能更有效和更快，而不需要用户设备中的白盒实现的代码混淆。可以使用委托协议来实现该分区。主要的优点是，即使给出密码过程的有限的代码大小，通过在黑盒部分中更有效地执行更多的计算密集型函数，并且在白盒部分中执行较少的计算密集型函数来提高系统的安全性。

摘要： A method and an apparatus that provides a hard problem based hashing mechanism to improve security of hash functions are described. The hashing mechanism can include a custom padding and/or a post processing to a hashed value strengthened via operations specifying a hard problem. In one embodiment, a new hash function may be provided or defined directly without introducing or relying on existing hash functions to embed security features based on this hard problem. The new hash functions can be used in usual constructions implying hash functions. For example, the standard HMAC construction could be applied on these hash functions, standard signature algorithms or authentication protocol, etc.

摘要： A Digital Rights Management (DRM) system for distribution of digital content such as audio or video uses a method to enhance security of the content from unauthorized access and use, including access by unauthorized players. The method does not necessarily require a token exchange and thereby minimizes storage demands on the server which distributes the digital content. The system generates and distributes keys for decryption of the digital content whereby the keys are unique to a specific player and user account.

摘要： In the field of computer enabled cryptography, such as a block cipher, the cipher is hardened against an attack by protecting the cipher key, by applying to it a predetermined linear permutation before using one key to encrypt or decrypt a message. This is especially advantageous in a “White Box” environment where an attacker has full access to the cipher algorithm, including the algorithm's internal state during its execution. This method and the associated computing apparatus are useful where the key is derived through a process and so is unknown when the software code embodying the cipher is compiled. This is typically the case where there are many users of the cipher and each has his own key, or where each user session has its own key.
摘要翻译：在诸如分组密码的计算机启用的密码学领域中，通过在使用一个密钥加密或解密消息之前，通过保护加密密钥对其进行预定的线性置换，来抵御攻击而加密密码。这在“白盒”环境中特别有利，攻击者可以完全访问密码算法，包括算法的执行过程中的内部状态。该方法和相关联的计算装置在通过过程导出密钥是有用的，并且当体现密码的软件代码被编译时是未知的。这通常是密码的用户很多，每个都有自己的密钥，或者每个用户会话都有自己的密钥的情况。

摘要： In the field of computer enabled cryptography, such as a keyed block cipher having a plurality of sequenced rounds, the cipher is hardened against attack by a protection process. The protection process uses block lengths that are larger or smaller than and not an integer multiple of those of an associated standard cipher, and without using message padding. This is operative in conjunction with standard block ciphers such as the AES, DES or triple DES ciphers, and also with various block cipher cryptographic modes such as CBC or EBC.

摘要： Disclosed herein are systems, methods, and computer readable-media for performing data encryption and decryption using a stream or block cipher with internal random states. The method includes splitting the input data into a predetermined number of blocks and processing each block. The processing includes creating sub-blocks, permuting the sub-blocks, replacing bytes using a lookup table, rotating bits, performing expansion and combining sets of bits. The element of randomness employed in this process allows for the same input to yield the same output, with differing internal states.

摘要： This discloses, in the computer data security field, a cryptographic hash function process embodied in a computer system and which may be keyless, but is highly secure. The process is based on the type of randomness exhibited by a heap or stack of physical objects such as a heap of pieces of fruit and involves modeling the behavior of such a heap when pieces are removed from the heap. Computation of the hash value (digest) is thereby the result of executing a heap model algorithm using the message as an input to initialize the heap, then executing the heap model algorithm which logically models the process of serially removing objects (pieces of fruit) from the heap at various locations in the modeled heap.

摘要： Disclosed herein are systems, methods and computer-readable media to perform data encryption and decryption using a derivation function to obtain a key per page of data in a white-box environment. The method includes sharing a master key with the sender and receiver, splitting the input data into blocks and sub-blocks, and utilizing a set of keys and a master key to derive a page key. In another aspect of this disclosure, the key validation and shuffling operations are included. This method allows for the derivation of a key instead of storing a predetermined key, thus maintaining system security in a white-box environment.
