Patent number: 11425122Abstract: A solution for circumventing censorship is disclosed. A first device connects to a first server hosted in a content delivery network (CDN). The CDN routes the first device's connection request to the first server. The first server responds by providing the first device with a configuration file that contains a plurality of second servers for the first device to access. The first device disconnects from the first server and hops between one or more of the plurality of second servers contained in the configuration file. By distributing the configuration file from a first server hosted in a CDN, the first device obfuscates the true endpoint of the connection. Thus, the first device obtains the configuration file without drawing the ire of censors. By hopping from server-to-server, the first device stays one step ahead of censors. Accordingly, a multi-prong approach to staying a step ahead of eavesdroppers, sniffers, and censors is described.Type: GrantFiled: August 13, 2018Date of Patent: August 23, 2022Assignee: Amazon Technologies, Inc.Inventors: Christopher Dowd, Christopher Lalonde, Thomas Michael Leavy, Arjun Bhatnagar, Dipakkumar R.

Patent number: 11405370Abstract: The present disclosure describes techniques for storing encrypted files in a secure file repository and transferring those encrypted files to one or more recipients. A user selects a file to upload to a secure file repository. A secure collaboration app on the user's device generates a first encryption key that is used to encrypt the file. The encrypted file is then uploaded to the secure file repository, which provides the secure collaboration app with a random file name and a location of the encrypted file. The secure collaboration app updates locally stored metadata of the first encrypted file. To securely transfer the file, the user generates a second encryption key, encrypts the metadata with the second encryption key, and transmits the encrypted metadata to one or more receivers. The one or more receivers decrypt the encrypted metadata and use the decrypted metadata to retrieve the file and decrypt it.Type: GrantFiled: February 2, 2017Date of Patent: August 2, 2022Assignee: Amazon Technologies, Inc.Inventors: Ernest W. Grzybowski, Christopher A. Howell, Thomas Michael Leavy, David A. Sugar, Dipakkumar R. Kasabwala

Patent number: 11362811Abstract: The present disclosure describes techniques for configuring and participating in encrypted audio calls, audio conferences, video calls, and video conferences. In particular, a call initiator generates a meeting identifier and a first meeting key, which are encrypted using a first encryption key and distributed to one or more participants of the call. The one or more participants decrypt the meeting identifier and the first meeting key, and use that information to participate in the encrypted call. Further, participants respond to the encrypted communication data by encrypting their reply data with the first meeting key. The call initiator decrypts the reply data using the first meeting key.Type: GrantFiled: March 16, 2020Date of Patent: June 14, 2022Assignee: Amazon Technologies, Inc.Inventors: Dipakkumar R.

The CDN routes the first device's connection request to the first server. The first server responds by providing the first device with a configuration file that contains a plurality of secondary servers for the first device to access. Accordingly, the first device disconnects from the first server and hops between one or more of the plurality of secondary servers contained in the configuration file.

Patent number: 10129229Abstract: The present disclosure describes systems and methods for authenticating a called party during the initialization stage of establishing a secure telecommunication channel to provide assurances to the initiator that they are communicating with whom they intended. A first user issues a challenge that includes a nonce to one or more second user devices. The second user's secure collaboration application receives the challenge, signs the nonce included in the challenge, and sends the response with the signed nonce to the first user. The first user receives the response and determines whether the signature of the first nonce is valid. If the signature is not valid, the first user's secure collaboration application terminates the secure telecommunication. However, if the signature received in the response is valid, the first user's secure collaboration application begins exchanging encrypted telecommunication data with the second user over a secure telecommunication channel.Type: GrantFiled: October 21, 2016Date of Patent: November 13, 2018Assignee: Wickr Inc.Inventors: Thomas Michael Leavy, Dipakkumar R.
