A computer system that interfaces with a blockchain is provided. The computer system receives match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier. A first blockchain transaction is generated based on the match data and stored to a blockchain. At least one further blockchain transaction is generates that splits the match into two different transactions—one between the first identifier and an intermediary and the second between the intermediary. These are recorded to the blockchain via the further blockchain transactions.

Software installed in the nodes in a communication network allows them to perform a “name server” function, which entails the management of a dynamic list of the client devices that are connected to the cloud, a “task” function, which entails the receipt and transmission of the packets, and an “authority” function, which entails the determination of the routes of the packets through the cloud. Each node is capable of performing only one function at a time. After completing a job, a node reverts to an undifferentiated, state awaiting its next performance request.

The invention is a method for monitoring a file in a file security system, including providing a first file representation of a file in which the file is disposed at a first location and first processing the first file representation to provide first signals in accordance with the first file representation. The first signals are stored in a central repository disposed at a second location wherein the second location is remote from the first location. A second file representation of the file is provided wherein the file is disposed at a third location remote from the second location. Second processing of the second file representation is performed to provide second signals in accordance with the second file representation. The first signals are accessed from the central repository and the first signals are compared with the second signals. A status of the file is determined in accordance with the comparing.

A method and apparatus for securing and, optionally, distributing an information stream by divided the information stream into a collection of segments and compressing the segments, rearranging the order of the segments and encrypting the segments.

Pure random numbers from a sheet within a one-time pad are employed to encrypt the bytes of a source data packet and to order the encrypted bytes in a random order within the encrypted data packet. Pure random numbers fill remaining positions within the encrypted data packet. The resulting encrypted data packet is unconditionally secure (i.e., unbreakable). Sheets within the one-time pad are utilized only once, and the one-time pad is replaced when exhausted. For electronic checking applications, the one-time pad is distributed to the user stored in an electronic checkbook, with a copy retained by the bank. For cellular telephone applications, the one-time pad is stored in a replaceable memory chip within the mobile unit with a copy retained at a single, secured central computer. For client-server applications or applications involving sales over the Internet, the one-time pad may be provided to the user on a floppy disk or CD-ROM, with a copy retained by the vendor.

A method is disclosed for modifying an iterated block cipher by controlling the operations and transformations that cause diffusion. In one embodiment which is applicable to any iterated block cipher (12), a diffusion function (10), during encryption, is selected based on a parameter which measures the order of permutation of the diffusion function (10) and applies the diffusion function (10) to the encryption routine (12). The user chooses the required amount of diffusion for a given block of plaintext (11). The plaintext (11) is then encrypted using the modified diffusion function (10) to produce a ciphertext (14) which is then sent over a communications channel (16) which may be noisy. At the receiving end (18) of the communications channel (16), the received ciphertext (20), which now may be corrupted by bit errors, is passed through an iterated block cipher decryption routine (22) using the same diffusion function (10) selected earlier during encryption. In a second embodiment, the SCOPE method is applied to the DES encryption and decryption standard. The expansion bits (82) of DES are replaced with a minicipher (98a-98n), and the DES standard permutation box (88) is replaced with a permutation box (104a-104n) modified according to a user-specified order of permutation. In a third embodiment, the SCOPE method is applied to the AES encryption and decryption standard. In the SCOPE-enhanced version of AES, diffusion is controlled by altering the diffusion of the “MixColumn” or “InvMixColumn” transformation based on its branch number and by changing the number of shifts in the “ShiftRow” or “InvShfitRow” transformations.
