Abstract: A system and method for of temporary password management may include: obtaining, by a password management entity, a request to login a local device into an authentication authority; generating, by the password management entity, a temporary password; sending, by the password management entity, the temporary password to the authentication authority; sending, by the password management entity, the temporary password to a user device; obtaining, at the authentication authority the temporary password from the local device; comparing, by the authentication authority, the temporary password obtained from the local device with the temporary password obtained from the password management entity; and authorizing the login if a match is found.

Abstract: A system and method for securing a communication channel may include obtaining a first value by first and second devices. A second value may be randomly selected by the first device and may be provided to the second device. The first and second devices may independently from one another apply a function to the first and second values and may use a result of the function to secure and authenticate a communication channel between the first and second devices.

Abstract: 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.
