摘要： In the computer data security field, cryptographic hash function processes embodied in a computer system and which are typically keyless, but are highly secure. The processes are based on the type of randomness exhibited by well known table “cue sports” games such as billiards, snooker, and pool played on a billiards table involving the players striking one of a plurality of balls with a cue, the struck ball then hitting other balls, the raised sides of the table, and in some cases one or more balls going into pockets in the corners and/or sides of the table. Computation of the hash value (digest) is the result of providing a model (such as expressed in computer code) of such a game algorithm and using the message as an input to the game algorithm, then executing the game algorithm. A state of the game after one or several “shots” gives the hash digest value of the message.

摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable media for deriving a deterministic binary value. The method consists of generating a graph from multiple inputs, formalizing the graph, calculating paths between starting and ending nodes in the graph using a shortest path algorithm and performing a digest operation based on the derived paths to generate a deterministic binary value. In another aspect of this disclosure, authentication is performed utilizing deterministic binary values and a graph-merging function. This method allows for diversity in complexity, thus maintaining security on different computer platforms.

摘要： A hash provides aggregation properties, and allows distributed and/or concurrent processing. In an example, the hash operates on message M, and produces a multiplicative matrix sequence by substituting a 2×2 matrix A for binary ones and substituting a 2×2 matrix B for binary zeros in M. A and B are selected from SL2(R), R=F2[x]/(P), F2[x] being the set of polynomials degree with coefficients in F2={0,1}, and (P) is the ideal of F2[x] generated by irreducible polynomial P(x) order n=12/4. The matrix sequence is multiplied to produce a 2×2 matrix, h, with n bit length entries. A function converts h into an l×l matrix, Y. Two l×l invertible matrices with randomly chosen F2 entries, P and Q, are accessed. P pre-multiplies Y and Q−1 post-multiplies Y to produce a final hash value. M can be subdivided into m1 . . . mt, corresponding h1 . . . ht can be produced, and the Y matrix produced from a product of h1 . . . ht to get the same hash value. Respective P and Q combinations can be unique to and pre-shared with each entity pair, so only those entities can compute valid hash data. Other hash functions and implementations can be provided according to this example.

摘要： A computer enabled secure method and apparatus for generating a cryptographic key, to be used in a subsequent cryptographic process, where the key is to be valid only for example during a specified time period. The method uses a polynomial function which is a function of an input variable such as time, and dynamically computes the key from the polynomial. This is useful for generating decryption keys used for distribution of encrypted content, where the decryption is to be allowed only during a specified time period.

摘要： In the field of computer software, obfuscation techniques for enhancing software security are applied to compiled (object) software code. The obfuscation results here in different versions (instances) of the obfuscated code being provided to different installations (recipient computing devices). The complementary code execution uses a boot loader or boot installer-type program at each installation which contains the requisite logic. Typically, the obfuscation results in a different instance of the obfuscated code for each intended installation (recipient) but each instance being semantically equivalent to the others. This is accomplished in one version by generating a random value or other parameter during the obfuscation process, and using the value to select a particular version of the obfuscating process, and then communicating the value along with boot loader or installer program software. This boot loader then selects which particular process to use for the code execution at the time of installation in accordance with the value. This results in different versions of the obfuscated code being provided to each recipient installation, which further enhances security of the code against reverse engineering by hackers.

摘要： Method and apparatus for ensuring randomness of pseudo-random numbers generated by a conventional computer operating system or electronic device. Typically pseudo-random number generators used in computer operating systems or electronic devices may be penetrated by a hacker (pirate), who penetrates a cryptographic or other supposedly secure process using the random numbers by tampering with the input random numbers, thus making them nonrandom. The present method and apparatus are intended to verify such random numbers to make sure that they are indeed random enough, by applying suitable random tests. Only if the values pass the test are they passed on for use in the cryptographic or other process. If they fail the test, a new set of random numbers is requested from the pseudo-random number generator. These are again tested. Further a diversity function may be applied to the random numbers even if they have passed the random number test in order to improve their randomness. This diversity function is for instance double encryption. An anti-replay feature is also included by which the pool of random numbers is subject to a check on each cycle to make sure that there has been no duplication of the input random numbers.

摘要： Some embodiments of the invention provide a content-distribution system for distributing content under a variety of different basis. For instance, in some embodiments, the content-distribution system distributes device-restricted content and device-unrestricted content. Device-restricted content is content that can only be played on devices that the system associates with the particular user. Device-unrestricted content is content that can be played on any device without any restrictions. However, for at least one operation or service other than playback, device-unrestricted content has to be authenticated before this operation or service can be performed on the content. In some embodiments, the system facilitates this authentication by specifying a verification parameter for a piece of device-unrestricted content. The content-distribution system of some embodiments has a set of servers that supply (1) media storage structures that store content, (2) cryptographic keys that are needed to decrypt device-restricted content, and (3) verification parameters that are needed to verify device-unrestricted content. In some embodiments, the device that receives the media storage structure inserts the received cryptographic key or verification parameter in the received media storage structure. In some embodiments, the set of servers also supply cryptographic content keys for the device-unrestricted content. These keys are used to decrypt the content upon arrival, upon first playback, or at some other time. However, some embodiments do not store these cryptographic keys in the media storage structures for the device-unrestricted content.
