According to some embodiments, a certification authentication method includes receiving a list of third party root certificates from a remote server, the list of third party root certificates including at least one association between a program configured to run on the computing apparatus and a public key for authenticating communication between the program and an associated server of the program. The method may also include authenticating the list of third party root certificates. The method may also include initiating a communication between the computing apparatus and the associated server and authenticating the communication with the associated server using the public key. Furthermore, the method may also include loading the program onto the one or more memories during a bootstrapping process in response to determining that the communication with the associated server is authentic.Type: GrantFiled: August 12, 2021Date of Patent: February 27, 2024Assignee: Capital One Services, LLCInventor: Srinivasan Rangaraj

Patent number: 11496456Abstract: This disclosure includes techniques for using multiple cryptographic certificates for a secure connection. One embodiment is a method including: receiving by a client N public encryption keys over a network from a server, wherein N is an integer greater than 1; generating N session keys in response to receiving the N public encryption keys; encrypting each of the N session keys with a respective one of the N public encryption keys; subsequent to encrypting each of the N session keys, sending the N session keys encrypted over the network to the server; encrypting, with a first one of the N session keys, a first portion of a payload associated with a first message; encrypting, with a second one of the N session keys, a second portion of the payload associated with the first message; and sending the first message, comprising the payload encrypted, to the server from the client.Type: GrantFiled: July 28, 2020Date of Patent: November 8, 2022Assignee: PayPal, Inc.Inventor: Srinivasan Rangaraj

Patent number: 10997594Abstract: 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.Type: GrantFiled: June 28, 2018Date of Patent: May 4, 2021Assignee: PAYPAL, INC.Inventor: Srinivasan Rangaraj
