Appl. No.:

17/352355

Inventors:

SAUL TROEN - NEW YORK NY, US
Christopher Howell - Honolulu HI, US

International Classification:

H04L 9/08

Abstract:

A method and device are provided for secure internet communication between a computing device and a server. The method employs non-extractable data stored within the device for the generation of a pair of master encryption keys, and the secure, non-internet transfer of one of the pair of keys to the server. Thereafter, communications between the device and the server are encrypted with one-time keys, the one-time keys being themselves encrypted with the master keys. At no time are either of the master keys transmitted over the internet, and at no time are the master keys stored together in a single device.

International Classification:

H04L 9/14
H04L 29/06
H04L 9/32

Abstract:

The present application describes a method, system, and non-transitory computer-readable medium for end-to-end encryption during a secure communication session. According to the present disclosure, a first device initializes a secure communication session with at least one second device. Initializing the secure communication session includes transmitting an invitation to a secure communication session to the at least one second device. The at least one second device may generate a transmission root key, which may be used to derive a first key for encrypting data transmitted to the first device and a second key for decrypting received data from the first device. The at least one second device may transmit the transmission root key to the first device, which may use the transmission root key to derive a first key to encrypt data transmitted to the at least one second device and a second key to decrypt data received from the at least one second device.

International Classification:

H04L 29/06
H04L 9/08
H04L 9/32
G06F 21/60

Abstract:

The present disclosure describes techniques that allow for a client-side application, located on a first client device, to generate a random encryption key and encrypt locally-stored application data with the random encryption key. In order to ensure that the client-device application is unable to decrypt the locally-stored encrypted application data prior to authenticating with an external authentication source (i.e., SSO, IdP), the client-side application divides the random encryption key into at least a first share and a second share according to a secret sharing algorithm. The first share is transmitted to a trusted third party, while the second share is encrypted locally and stored in a secure location on the client device. Upon successful authentication, the trusted third party returns the second share to the first client device. The client-side application derives the random encryption key and decrypts the locally-stored encrypted application data to be used by the client-side application. By dividing the key used to encrypt the client-side application data and storing one of the secret shares necessary to deriving the key at a trusted third party, the present disclosure solves the problem of how to encrypt local application data when the login credentials for the application are managed by a trusted third party, such as an SSO system.

- San Francisco CA, US
Christopher Howell - Freehold NJ, US

Assignee:

Wickr Inc. - San Francisco CA

International Classification:

H04L 9/32
H04L 9/08

Abstract:

The present disclosure describes a method, system, and non-transitory computer readable medium that includes instructions that permit users of different secure communication networks to exchange secure communications. A secure communication platform includes a user database that allows users from different secure communication networks to access keys for recipients outside of their network. Additionally, the secure communication platform provides a high degree of trust regarding the sender's identity, allowing the receiving network to trust the sender.
