摘要： Method and apparatus to detect clock roll-forward attacks in a computing device or similar system. This protects against hackers who tamper with the system clock of, for instance, a digital media playback device in order to access a content item which has been rented for a limited time. By detecting clock roll-forward tampering, the present method and system prevent such hackers from accessing the content item outside its authorized rental time period.

摘要： A computer enabled method and apparatus for encrypting and decrypting data using a keyless transformation cryptographic technique. Data is protected using a keyless (unkeyed) complex mathematical transformation, in contrast to a traditional cryptographic algorithm using a secret key. This approach is resistant to both static analysis (hacking) performed on executable encryption/decryption code, as well as dynamic analysis performed during execution (runtime) of ciphering or deciphering. The method uses a family of asymmetric data transformations based on Galois field polynomials.

摘要： Method and apparatus for data security using exponentiation. This is suitable for public key cryptography authentication and other data security applications using a one-way function. A type of exponentiation is disclosed here where the bits of an exponent value expressed in binary form correspond to a course (path) in a given graph defining the one-way function. This uses an approach called here F sequences. Each value is in a ladder of a sequence of values, as defined from its predecessor values. This ladder satisfies certain algebraic identities and is readily calculated by a computer program or logic circuitry.

摘要： The ability to utilize smart card based Internet applications is facilitated by enhancing the functionality of smart cards dedicated to other applications, to enable them to connect to and interoperate with Internet application servers. The functionality of subscriber identification module (SIM) card is enhanced to incorporate the information necessary to interact with an Internet-based application service provider. The user can also employ a conventional smart card to access an Internet application from a personal computer or other terminal equipped with a conventional smart card reader, and use the SIM card to interact with application when access to a conventional smart card reader is not available. The application server recognizes the distinction between access with the two different types of cards, and ensures that both cards are synchronized with one another.

摘要： In the field of computer enabled cryptography, such as a cipher using lookup tables, the cipher is hardened against an attack by a protection process which obscures the lookup tables using the properties of bijective functions and applying masks to the tables' input and output values, for encryption or decryption. 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 for protection against known attacks on “White Box” ciphers, by obfuscating lookup table data, thereby increasing the cipher's complexity against reverse engineering and other attacks.

摘要： In the field of computer enabled cryptography, such as a keyed block cipher having a plurality of rounds, the cipher is hardened against attack by protecting the round keys by (1) combining several cipher operations using a pair of sub-keys (round keys) into one table look-up, or (2) a key masking process which obscures the round keys by providing a masked version of the key operations for carrying out encryption or decryption using the cipher. This approach is especially advantageous in an insecure “White Box” environment where an attacker has full access to execution of the cipher algorithm, including the algorithm's internal state during its execution.

摘要： In the field of computer enabled cryptography, such as a keyed block cipher having a plurality of rounds, the cipher is hardened against an attack by protecting the cipher key by means of a key expansion process which obscures the cipher and/or the round keys by increasing their lengths to provide an expanded version of the keys for carrying out encryption or decryption using the cipher. 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： In the computer data security field, a cryptographic hash function process embodied in a computer system and which is typically keyless, but is highly secure. The process is based on the type of chaos introduction exhibited by a game process such as the well known shuffling of a deck of playing cards. Computation of the hash value (digest) is the result of executing in a model (such as computer code or logic circuitry) a game algorithm that models the actual game such as a playing card shuffling algorithm using the message as an input to the algorithm, then executing the card shuffling algorithm on the input. A state (order) of the modeled deck of cards after a shuffle (or multiple shuffles) gives the hash digest value.

摘要： Disclosed herein are systems, computer-implemented methods, and tangible computer-readable media for obfuscating constants in a binary. The method includes generating a table of constants, allocating an array in source code, compiling the source code to a binary, transforming the table of constants to match Pcode entries in an indirection table so that each constant in the table of constants can be fetched by an entry in the indirection table. A Pcode is a data representation of a set of instructions populating the indirection table with offsets toward the table of constants storing the indirection table in the allocated array in the compiled binary. The method further includes populating the indirection table with offsets equivalent to the table of constants, and storing the indirection table in the allocated array in the compiled binary. Constants can be of any data type. Constants can be one byte each or more than one byte each. In one aspect, the method further includes splitting constants into two or more segments, treating each segment as a separate constant when transforming the table of constants, and generating a function to retrieve and reconstruct the split constants.
