Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

A system may include a first automated teller machine (ATM) and a second ATM, wherein the first ATM and the second ATM are in communication via a local area network. The first ATM obtains a user input value, generate an encryption key based on the user input value, and generates encrypted authentication information based on the encryption key. The first ATM also obtains a first biometric reading, updates a user record based on the first biometric reading, and stores the encrypted authentication information at the first ATM in association with the user record. The second ATM obtains a second biometric reading and a duplicate value, retrieves the encrypted authentication information associated with the user record based on the second biometric reading, generates a decryption key based on the duplicate value, and decrypts the encrypted authentication information to retrieve the authentication information.

A method for creating single-use authentication messages includes creating, at a consumer network function of a core network of a telecommunications network, a message hash of at least a subset of a request message. The method includes adding, at the consumer network function, the message hash to a client credentials assertion (CCA) token for the consumer network function. The method includes sending, from the consumer network function, the request message with the CCA token to a producer network function.

Each tenant of a secure web gateway (SWG) is issued a secret key. A user accesses a unique secret key derived from the tenant's secret key and loads the secret key into an application which generates time-based one time passwords (TOTPs). When the SWG receives a connection request from a client and cannot decrypt the network traffic, the SWG challenges the client request and indicates an authentication scheme to be used. The client obtains user credentials, constructs a response to the challenge based on the authentication scheme, and issues a connection request to the SWG which indicates the response. The SWG determines an expected response based on a locally generated TOTP and the secret key of the corresponding tenant. If the expected response matches the provided response, the SWG authenticates the user, allows the connection request, and whitelists the client for a period longer than the lifetime of the TOTP.

A method comprising receiving, by a one-time pad (OTP) hub, from a first user of a computer network, a communication encrypted with an OTP associated with said first user, wherein said communication is intended for a second user; encrypting, by said hub, said communication with an OTP associated with said second user; decrypting, by said hub, said communication with an OTP associated with said first user; and delivering said communication to said second user.

Improved systems and methods of authenticating a user using a mobile device to access a secure electronic portal are provided. A user may be enabled to quickly and securely log onto a website or other electronic portal using a handheld electronic device. In certain embodiments, multifactor authentication is utilized to improve the security of the authentication process.

The disclosure generally relates to a system and method for randomly generating unlock codes and identifiers for locks, and creating unlock code and identifier pairs. In an exemplary embodiment, the invention is integrated with, or part of, a distributed management system that controls access to various locations, such as, for example, self-storage units, hotel rooms, apartment buildings, storage containers, short-term housing rentals, lockers, equipment rooms, vaults, hospitals, airports, government facilities, nuclear power facilities, water treatment facilities, weapon storage facilities, aircraft cockpits, and any other setting that requires restricted, selective, or monitored access that can be remotely controlled, whereby users can receive unlock codes electronically on their mobile device.

A mobile voting system and method are provided. The mobile voting system may include a mobile messaging aggregator configured to receive voter verification requests from one or more mobile carriers, and a mobile voter verification server configured to verify a voter's identity in response to a voter verification request and generate a link to a mobile ballot once the voter's identity has been verified. The mobile messaging aggregator may cause the link to the mobile ballot to be transmitted to a mobile device of the voter, which when selected by the voter, allows the voter to cast a vote.

A rollover system is provided to facilitate transitioning of client devices in a shared account network environment, from an old password to a new replacement password. The switching of passwords may take place gradually during a rollout period for client devices without required downtime and reducing a risk of lockouts. During the rollover period, a prior salt is temporarily carried over to a new verifier for the replacement password. Two new verifiers are generated: a temporary new verifier using the old salt for verification during the rollover period and another new verifier using a different new salt for verification after the rollover period had expired. During the rollover period, authentication involves the use of the temporary new verifier with the old salt or by the old verifier and old salt of the prior password. After the rollover period, authentication is based on the new verifier with a new salt.
