It also supports exclusion of a certain set of characters from the ciphering process. An encryption algorithm is provided that encrypts the input plaintext data while preserving its original format and length, and a corresponding decryption algorithm is provided. The cipher advantageously embodies the encryption and decryption of multi-byte values, composite datasets, and credit card numbers, thus fitting a variety of industrial needs. | 2018-08-23 |
20180241546 | SPLITTING DIGITAL PROMISES RECORDED IN A BLOCKCHAIN - A method and system to securely split a digital promise that is recorded in a blockchain. A digital promise represents a promise by a promisor to pay a promisee an asset when a specified condition is satisfied. The specified condition may be fulfillment of a digital contract, also recorded in the blockchain, to which the digital promise is linked. When splitting a digital promise, a split transaction is recorded indicating a split into a first child digital promise and a second child digital promise. In each child digital promise, the promisor promises to pay a child promisee a portion of the asset when a specified child condition is satisfied. When a digital promise is split, the digital promise itself is no longer payable, but the child digital promises are payable when both the specified condition and the specified child condition for the child digital promise are satisfied. | 2018-08-23 |
20180241547 | SYSTEM, APPARATUS, AND METHOD FOR SECURING DATA USING A GRAPHICS PROCESSOR - A system, apparatus, and method are provided for securing data using a graphics processor.

20180241548 | METHOD AND SYSTEM FOR AUTHENTICATING AND PRESERVING THE INTEGRITY OF COMMUNICATION, SECURED BY SECRET SHARING - A system and method for providing secure communication between a source and a destination that is secured by secret sharing, during a vulnerability window in which all secret shares are collected in one or more points along the communication paths. Accordingly, during the regular operation of the communication protocol, a common random secret OTP is created by sending random bits from the sender to the receiver and the source is allowed to perform bitwise XOR operation between the information to be sent and the common random secret OTP, prior to using secret sharing. The results of the bitwise XOR operation are sent to the destination using secret sharing and the destination reconstructs the random secret and decrypts the received data, using the common established random secret. The common random secret is based on polynomial randomization being transferred from the source to the destination using secret sharing. The coefficients of a selected polynomial are randomly chosen at the sender side and are known both to the sender and the receiver. An x value is selected for each set of chosen coefficients, for which there is a corresponding y value. Pairs of x and y values transmitted from the sender to the receiver, where each pair represents a secret share. The transfer of polynomial randomization is repeated for every bit/byte or for any group of bits of the message to be transmitted, while in each time randomly choosing a different set of coefficients. At the end, the destination decrypts the message by collecting all shares being pairs of the received x and y values and reconstructs the selected polynomial from all collected shares. | 2018-08-23 |
20180241549 | KEY GENERATION METHOD AND APPARATUS USING DOUBLE ENCRYPTION - The disclosure provides a key generation method and apparatus. The key generation method comprises: encrypting a first key factor generated by a first device with an initial key, and sending the encrypted first key factor to a second device through a first secure channel, wherein the initial key is a key preset for the first device and the second device; receiving, through the first secure channel, a second key factor encrypted with the initial key, wherein the second key factor is generated by the second device; decrypting the second key factor encrypted with the initial key and received through the first secure channel, so as to obtain the second key factor; and generating a shared key between the first device and the second device according to the first key factor and the second key factor. According to the disclosed embodiments, a gateway device is unable to acquire a shared key negotiated between a first device and a second device, ensuring the security of data transmitted there between, and further reducing the risk of data being illegally captured during transmission. | 2018-08-23 |
