150 results about "End-to-end encryption" patented technology

End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation.

Communication system architecture and operating methodology providing a virtual neighborhood network

InactiveUS7142503B1Overcome bandwidth limitationIncreased peak bandwidth capacityError preventionFrequency-division multiplex detailsEnd-to-end encryptionTransceiver
A communication system (10) supports the provision of a plurality of dedicated communication resources (50–64), such as copper drops, RF links and optical fibers, to dedicated home-gateway devices (44–48) or distribution points (124). The communication resources (50–64) support broadband interconnection (104) between the dedicated home-gateway devices (44–48) or distribution points (124) and an access multiplexor (30) in a network (12). Each gateway device (44–48) or distribution point (124) generally includes a local RF transceiver (84) and associated control logic (80–82) that allows local communication (86) between gateway devices (44–48) and hence statistically multiplexed access (60–64, 89) to multiple communication resources, thereby providing increased bandwidth in uplink and / or downlink directions. With the control logic (80) operable to provide a routing and prioritisation / arbitration function, each gateway (44–48) is able to selectively engage use of supplemental, non-reserved communication resources usually associated with a dedicated ono-to-one connection between the access network (12) and at least one secondary gateway. Physical layer access to information routed via a secondary gateway within a virtual neighborhood network (90–92) comprising several gateways is restricted through an end-to-end encryption algorithm between an originating gateway and, at least, the access multilpexor (30).

Policy routing-based lawful interception in communication system with end-to-end encryption

Techniques are disclosed for lawfully intercepting information in communication environments with end-to-end encryption. For example, a method for intercepting encrypted communications exchanged between a first computing device and a second computing device in a communication network, wherein the interception is performed by a third computing device in the communication network, comprises the following steps. The third computing device obtains one or more packets having a packet address associated with one of the first computing device and the second computing device. The one or more packets are obtained by the third computing device, in response to at least one interception routing policy being implemented in at least one element in the communication network, such that the one or more obtained packets may be decrypted so as to obtain data contained therein. The third computing device preserves the packet address of the one or more obtained packets. The third computing device forwards the one or more packets toward a packet-destination one of the first computing device and the second computing device such that the packet-destination one of the first computing device and the second computing device is unable to detect from the one or more packets that the one or more packets were intercepted by the third computing device.

Embedded acceptance system

Methods and systems can provide for unified processing of merchant transactions over various payment channels over which the transactions originate, such as in-person retail transactions and e-commerce transactions. For example, transactions can be received from payment channels through different payment channel-specific interfaces. The transactions from the various payment channels can then be sent to an entry point module that centrally manages the transactions. An orchestrator can then identify payment channel-agnostic transaction services to be applied to the transactions. This can allow for a unified end-to-end encryption implementation across a merchant's enterprise, reducing management costs and improving overall security. Similarly, universal tokenization services, payment and fraud management can be provided across a merchant's entire enterprise.

Compression and secure, end-to-end encrypted, zfs cloud storage

Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.

Session key exchange key

A system and method for employing a key exchange key to facilitate secure communication is provided. The key exchange key can be employed, for example, to encrypt and / or decrypt dialog session key(s) that are used to encrypt and / or decrypt message(s) that form a dialog between an initiator system and target system. In one example, a key exchange key is unique to a service pair, while a dialog session key is unique to a particular dialog between the service pair. The system can facilitate end-to-end encryption of message data in a dialog—the message data is encrypted at one dialog endpoint and not decrypted until it reaches the other dialog endpoint. The system can be employed to facilitate secure dialog with minimal performance overhead when compared with conventional system(s). Optionally, the system can facilitate load balancing (e.g., among deployed instances of a service). In this example, secured dialogs to a service can be location transparent so that a dialog targeted to a service can be able to talk to any instance of the same service transparently without any additional security setup. The system employs both public key / private key asymmetric encryption technique(s) and symmetric encryption technique(s) to authenticate and secure information exchanged between an initiator system and a target system.

Role-oriented database record field security model

A database management system implements a role-oriented authorization scheme that facilitates operating system (OS) supported encrypted field access for a table in the database. A security model provides for various roles that have varying responsibilities and rights with respect to the database tables and the data supported therein. In this approach, data that is considered sensitive is encrypted. A system administrator role is authorized to create, update, and maintain a table but is not authorized to view sensitive field data, i.e., data stored in encrypted columns of the table. A security administrator role is authorized to define column masks with OS-enforced security access control to the sensitive field data. By separating (fencing) these responsibilities, the security model enforces end-to-end encryption across the entire database management system.
