Abstract: Systems and methods for message encryption include transmitting, to a first device through a first communication channel, a modification rule message including a modification rule. A first message is encrypted using a first key to generate an encrypted message. The encrypted message is modified based on the modification rule to generate a modified encrypted message. The modified encrypted message is transmitted to the first device through a second communication channel.

Abstract: Methods, systems, and computer program products are included for authenticating computing devices. An exemplary method includes associating a security key with an operating system of a first computing device, wherein the security key is generated from a serial number corresponding to the first computing device. A token corresponding to the security key is sent to a second computing device. The token is accessed by the second computing device to authenticate the first computing device. An authenticated session is established between the first computing device and the second computing device. Within the authenticated session, a connection is provided between the first computing device and the second computing device.

Abstract: A method is provided that includes assigning one or more first records of a first table and one or more second records of a second table to corresponding range groups of a plurality of range groups. The method further includes comparing at least one record of the first table with at least one record of the second table, where the at least one record of the first table and the at least one record of the second table are assigned to a first range group of the plurality of range groups. The method also includes, based on the comparing, identifying a parent record and a child record and segmenting the parent record based on the child record. Further, the method includes subsequent to the segmenting the parent record, performing a join operation on the first table and the second table.

Abstract: Systems and methods for authenticating a user are provided. A user requests pregenerated tokens from a service provider and selects one or more conditions of use (e.g., time, location, and number of uses) to be attached to the pregenerated tokens. The service provider transmits the pregenerated tokens to the user for storing on the user device that requested the pregenerated tokens. When the user attempts to log in to the service provider, the user device selects the appropriate pregenerated token based on the conditions of use. The service provider checks whether the conditions of use attached to the token are met before authenticating the user.
