A computer implemented method for managing a connection between a device and a server resource, the method comprising: establishing the connection between the device and a first server of the server resource; registering a connection identifier relating to the connection between the device and the first server in a first database entry of a database arrangement; pre-computing, at the first server, an encrypted alert for the device, the alert being provided with a pre-defined future communication sequence number; and transmitting the alert from the first server to the database arrangement for storage in association with the first database entry of the database arrangement.

Visual image authentication
11693944 · 2023-07-04 · ·

Methods and systems described herein authenticate a user and help secure transaction. A display screen presents images that are difficult for malware to recognize but a person can recognize. In at least one embodiment, a person communicates transaction information using visual images received from the service provider system. In at least one embodiment, a user selects a sequence of visual images as a means of authenticating the user and logging into a financial account or other corporate account. In some embodiments, methods and systems are provided for determining whether to grant access, by generating and displaying visual images on a screen that the user can recognize, and select. In an embodiment, a user presses his or her finger or fingers on a display screen to select images as a method for authenticating and protecting communication from malware. In an embodiment, non-determinism in hardware helps unpredictably vary the image selected, the image location, generate noise in the image, or change the shape or texture of the image. In some embodiments, visual image authentication helps Alice and Bob detect if Eve has launched a man-in-the-middle attack on their key exchange.

SYSTEMS, METHODS, AND DEVICES FOR ENCRYPTED DATA TRANSFER

A network interface controller includes processing circuitry configured to pair with a local root of trust of a host device connected to the network interface controller and provide a key to an encryption device of the host device that enables the encryption device to encrypt data of one or more host device applications using the key. The encrypted data are stored in host device memory. The processing circuitry is configured to share the key with a remote endpoint and forward the encrypted data from the host device memory to the remote endpoint.

Secure session capability using public-key cryptography without access to the private key

A first server receives a set of cryptographic parameters from a second server. The set of cryptographic parameters is received from the second server as part of a secure session establishment between a client device and the second server. The first server accesses a private key that is not stored on the second server. The first server signs the set of cryptographic parameters using the private key. The first server transmits the signed set of cryptographic parameters to the second server. The first server receives, from the second server, a request to generate a premaster secret using a value generated by the second server that is included in the request and generates the premaster secret. The first server transmits the premaster secret to the second server for use in the secure session establishment between the client device and the second server.

Message processing for subscriber sessions which stretch over different network domains

A technique for hiding topological information in a message that leaves a trusted network-domain is presented. The message pertains to a subscriber session and comprises a Fully Qualified Domain Name (FQDN) of a message originator. The originator is located in a first network domain, and the message is directed towards a destination in a second network domain. A method aspect comprises the steps of receiving the message, determining the FQDN comprised in the message and determining an identifier associated with the message. The identifier comprises at least one of a subscriber identifier, a session identifier and a destination identifier. Further, the method comprises applying a cryptographic operation on the FQDN and the identifier, or on information derived therefrom, to generate a cryptographic value. The message is then processed by substituting at least a portion of the FQDN with the cryptographic value prior to forwarding the message towards the second network domain.

System for securing deployed security cameras

Example embodiments provide systems and methods for securing a deployed camera. A security apparatus is coupled to the deployed camera and accesses video content from the coupled camera. The security apparatus accesses video content from the coupled camera, splits the video content within a plurality of RTP packets, encrypts payloads of the RTP packets, embeds in a header of the encrypted RTP packets, at least two key identifications for decryption of the encrypted RTP packets, and transmits the plurality of RTP packets over a network to a video management system.

Centralized configurator server for DPP provisioning of enrollees in a network

Systems and methods are provided for implementing a centralized configurator server/service in the cloud that can take the place of conventional mobile devices used for provisioning IoT devices or WiFi clients in a network. In order to provision the IoT devices or WiFi clients, a mobile device or access point (AP) may be used to relay Device Provisioning Protocol (DPP) messages and/or information between the centralized configurator server/service and the IoT devices or WiFi clients.

Managing permissions to cloud-based resources with session-specific attributes

Techniques for managing permissions to cloud-based resources with session-specific attributes are described. A first request to create a first session to permit access to resources of a provider network is received under an assumed role. The first request is permitted based on an evaluation of a rule associated with the role. Session data including a user-specified attribute included with the first request is generated. A second request to perform an action with a resource hosted by the provider network is received. The user-specified attribute is obtained from the session data based at least in part on the second request. The second request is permitted based on an evaluation of another rule with the user-specified attribute.

Data provenance

Methods, systems, and devices for wireless communications are described. Aspects include a device generating data to be sent to a receiving device and determining to provide provenance for the data. The device may generate a data identifier based on an identifier generation key and encrypt the data using an encryption key generated from a key associated with an owner of the device. The device may sign they encrypted data transmission using a signing key where the signing key is based on the encrypted data and the data identifier. In some cases, the device may send the data to a receiving device via one or more proxy devices. In some cases, multiple device may send signed data transmissions to a proxy device and the proxy device may process the multiple data transmission and send the processed data to the receiving device. The receiving device may verify provenance of the data.
