Abstract: The invention provides a solution for secure authentication of an individual. The invention comprises methods and apparatus for secure input of a user's identifier e.g. PIN. An image of a keypad is superimposed over an operable keypad within a display zone of a screen associated with an electronic device. The keypad image and/or the operable keypad are generated by the device using a scrambled or randomised keypad configuration generated on or at the electronic device. The configuration or order of keys depicted in the image may or may not be scrambled or randomised. Thus, the order of keys depicted in the image do not correspond to the order of the keys in the operable keypad, so that when the user selects a ‘key’ depicted in the image on the screen, the underlying operable keypad is caused to operate and an encoded version of the user's input is received into memory on the device. The encoded input can be sent for decoding on a remote computer. The keypad configurations used for generation of the operable keypad(s) and/or keypad image(s) are generated using an input. The input could be a true or pseudo random number or biometric data relating to a user of the device. The device may be a mobile phone, a tablet computer, laptop, PC, payment terminal or any other electronic computing device with a screen.

Abstract: A fully homomorphic method and system for randomizing an input, wherein all computations are over a commutative ring is described. Equivalent methods for performing the randomization using matrices and polynomials are detailed, as well as ways to mix the matrix and polynomial functions. Addition, multiplication, and division of the matrix and polynomial functions is further described. By performing computations of the functions modulo N over a ring ZN, the functions are usable as encryption functions. The method and system can also be used for verifying that a returned result of a calculation performed by a third party is valid for any of the calculations described herein. Related methods, systems, and apparatus are also described.

Abstract: A computer system contains a module configured to receive a query, to request rows and columns from a data store, to add or remove rows in such a way that combinations of queries cannot be used to infer information about individuals in the data store. The module executes a statistical computation over the adjusted rows and columns to produce a perturbed answer so that neither the perturbed answer alone, nor repeats of the perturbed answer can be used to infer information about individuals in the data store.

Abstract: A random wave envelope is created from a set of bounded random numbers by additively combining a triangle, a square and a sine wave. The random wave envelope is then used to create a sequence of wave random numbers from the wave envelope, which are used to generate random-variant keys for encryption in place of the pre-placed encryption key. An ambiguity envelope is thus created over the transmission of data packets as random-variant-keys are used that are distinct and separate for each packet and may also be distinct and separate for each incoming and outgoing packet. The random-variant keys are only created at the time of the actual use for encrypting or decrypting a data packet and not before and then discarded after one time use. The random-variant keys may be used in wireless network using wireless access points, cellular phone and data networks and ad hoc mobile wireless networks.

Abstract translation: 通过将三角形，正方形和正弦波相加组合，从一组有界随机数产生随机波包络。 随机波包被用于从波包创建一个波序列，用于生成用于加密的随机变量密钥代替预先加密的密钥。 因此，对于数据分组的传输，由于对每个分组使用不同且分离的随机变体密钥，因此产生模糊度包络，并且对于每个输入和输出分组也可以是不同的和分离的。 随机变量键仅在实际使用时创建，用于加密或解密数据包，而不是之前，然后在一次使用后丢弃。 随机变量密钥可以用于使用无线接入点，蜂窝电话和数据网络以及ad hoc移动无线网络的无线网络中。

Abstract: Various methods and systems related to chaos-based pseudo-random number generation are presented. In one example, among others, a system includes a pseudo¬ random number generator (PRNG) to generate a series of digital outputs and a nonlinear post processing circuit to perform an exclusive OR (XOR) operation on a first portion of a current digital output of the PRNG and a permutated version of a corresponding first portion of a previous post processed output to generate a corresponding first portion of a current post processed output. In another example, a method includes receiving at least a first portion of a current output from a PRNG and performing an XOR operation on the first portion of the current PRNG output with a permutated version of a corresponding first portion of a previous post processed output to generate a corresponding first portion of a current post processed output.

Abstract: Techniques and mechanisms for generating a random number. In an embodiment, a first signal is received from a first cell including a first source follower transistor. Circuit logic detects for a pulse of the first signal and, in response to the pulse, generates a signal indicating detection of a first random telegraph noise event in the first source follower transistor. In another embodiment, a first count update is performed in response to the indicated detection of the first random telegraph noise event. The first count update is one basis for generation of a number corresponding to a plurality of random telegraph noise events.
