In a secure cloud for transmitting packets of digital data, the packets may be repeatedly scrambled (i.e., their data segments reordered) and then unscrambled, split and then mixed, and / or encrypted and then decrypted as they pass through media nodes in the cloud. The methods used to scramble, split, mix and encrypt the packets may be varied in accordance with a state such as time, thereby making the task of a hacker virtually impossible inasmuch as he or she may be viewing only a fragment of a packet and the methods used to disguise the data are constantly changing.

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.

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.

A system and method for authentication and digital signatures on memory-only supports, comprising a read-once memory unit storing secret arrays, whose contents are destroyed upon reading, a standard memory unit storing encrypted arrays, tree data authenticating the encrypted arrays to one single public key, and a certificate of the public key issued by a certificate authority. The memory support sends its public key and certificate to a verifier, receives a challenge which is signed by elements from secret arrays in the read-once memory. The verifier system checks the authenticity of the data revealed from the read-once memory by encrypting it and comparing the result to one of the encrypted arrays, and verifies that the encrypted array authenticates to the public key using tree data. Finally, the verifier checks the authenticity of the public key using the certificate.

A method and system for efficiently retrieving secured data by securely pre-processing provided access information, provides data store security based on only a single piece of access information, which is generally public, such as the proper name of a business or individual that is used to retrieve mailing address information.

NADO is a process for encrypting and decrypting information in a variety of cryptographic devices. The underlying process is a fast stream-like cipher that can be implemented efficiently in analog or digital hardware or in software. The NADO process makes use of three novel methods in cryptography: 1) A sequence of permutations which scrambles and spreads out the encrypted information; (2) A state generator built with a non-autonomous dynamical system to generate an unpredictable sequence of states; (3) One or more perturbators which perturb both the non-autonomous dynamical system and the sequence of permutations in a non-periodic way.
