Systems and methods for tokenization to support pseudonymization are provided herein. An example method includes receiving an input set, seeding a random number generator with one or more secret data, transposing the input set using a first random number/transposition parameter generated by the random number generator to create a transposed input set, transposing a token set using a second random number/transposition parameter generated by the random number generator to create a transposed token set, and generating a token by substituting transposed input set values with transposed token set values.

Methods, systems, and devices for encrypting and decrypting data. In one implementation, an encryption method includes inputting plaintext into a recurrent artificial neural network, identifying topological structures in patterns of activity in the recurrent artificial neural network, wherein the patterns of activity are responsive to the input of the plaintext, representing the identified topological structures in a binary sequence of length L and implementing a permutation of the set of all binary codewords of length L. The implemented permutation is a function from the set of binary codewords of length L to itself that is injective and surjective.

A secure method for data exchange between a terminal and a server is described. The server can use a cryptographic module configured to encrypt or decrypt a message based on input parameters comprising the message, a response to a challenge and a symmetric key. The terminal can use a white-box cryptography module constituting a white-box implementation of the cryptographic module of the server for this symmetric key.

An authentication and encryption protocol is provided that can be implemented within a single clock cycle of an integrated circuit chip while still providing unbreakable encryption. The protocol of the present invention is so small that it can co-exist on any integrated circuit chip with other functions, including a general purpose central processing unit, general processing unit, or application specific integrated circuits with other communication related functionality.

A method for detecting a fault injection is described. The method includes providing a secondary code, the secondary code including a predetermined function with a known expected result when the secondary code is executed with a known tested input. A primary code is executed in the data processing system. The primary code may be a portion of code that requires protection from a fault injection attack, such as for example, security sensitive code. The secondary code is executed in parallel with the primary code execution in the data processing system to produce an output. The output is compared with the known expected result to detect the fault injection attack of the data processing system. In one embodiment, the secondary code is not related to the primary code.

According to a first aspect of the invention, there is provided a method of deriving information from an optically readable security element, comprising: optically reading the optically readable security element, the optically readable security element comprising at least one optically readable structure, optically readable in response to excitation of the optically readable structure; the reading comprising determining data indicative of an optical property of the optically readable security element using first emission electromagnetic radiation, emitted in response to excitation of the optically readable structure; the deriving information further comprising using the determined data indicative of an optical property, in combination with a temporal excitation-emission relationship related to the optically readable structure, to derive the information.

An application-specific integrated circuit (ASIC) and method are provided for executing a memory-hard algorithm requiring reading generated data. A processor or state machine executes one or more steps of the memory-hard algorithm and requests the generated data. At least one specialized circuit is provided for generating the generated data on demand in response to a request for the generated data from the processor. Specific embodiments are applied to memory-hard cryptographic algorithms, including Ethash and Equihash.
