A computer-implemented method performed by a user device is provided. The computer-implemented method includes receiving a message including an encrypted credential from a server computer; determining a response shared secret using a private key and a server public key; decrypting the encrypted credential using the response shared secret to determine a credential; obtaining a key derivation parameter from the credential; determining a first cryptogram key using the key derivation parameter; generating a first cryptogram using the first cryptogram key; and sending the first cryptogram to a second computer.

A method for execution by a storage network begins by issuing a decode threshold number of read requests for a set of encoded data slices to a plurality of storage units of a set of storage units and continues by determining whether less than a decode threshold number of read requests has been received in a time window. The method continues by identifying one or more encoded data slices encoded data slices associated with read requests of the decode threshold number of read requests that have not been received and for an encoded data slice of the one or more encoded data slices, issuing a priority read request to a storage unit storing a copy of the encoded data slice. The method then continues by receiving a response from the storage unit storing the copy of the encoded data, where the storage unit storing the copy of the encoded data slice is adapted to delay one or more maintenance tasks in response to the priority read request.

A new cybersecurity incident is registered at a security incident response platform. At a playbook generation system, details are received of the new cybersecurity incident from the security incident response platform. At least some of the details correspond to a set of features of the new cybersecurity incident. A set or subset of nearest neighbors of the new cybersecurity incident is localized in a feature space. The nearest neighbors of the new cybersecurity incident are other cybersecurity incidents having a distance from the new cybersecurity incident within the feature space that is defined by differences in features of the nearest neighbors with respect to the set of features of the new cybersecurity incident. A custom playbook is created for responding to the new cybersecurity incident having prescriptive procedures based on occurrences of prescriptive procedures previously employed in response to the nearest neighbor cybersecurity incidents.

The invention relates to a method for managing exchanges of data between: —a probe (1) comprising a memory containing a probe digital certificate including a probe public key, —a terminal (2) comprising a memory containing a terminal digital certificate including a terminal public key, —a remote platform (3) configured to: .sup.∘deliver the probe digital certificate to the probe and .sup.∘deliver the terminal digital certificate to the terminal, characterised in that the method comprises the implementation of an authentication procedure consisting of the following steps:—a first step in which the probe verifies the identity of the terminal from the terminal digital certificate; —a second step in which the terminal verifies the identity of the probe from the probe digital certificate, and—a third step in which the probe, the terminal and the platform each generate an identical session key from the probe and terminal public keys.

Aspects of the disclosure relate to data sharding for transmission over a high generation cellular network. A computing platform may detect, via a communication network, transmission of data from a first computing device to a second computing device. Subsequently, the computing platform may intercept, prior to receipt of the transmission by the second computing device, the data. Then, the computing platform may shard the data into a first shard and a second shard. Then, the computing platform may identify, within the communication network, a first communication channel and a second communication channel. Then, the computing platform may send, to the second computing device, the first shard via the first communication channel, and the second shard via the second communication channel. Subsequently, the computing platform may merge, the first shard and the second shard, to reconfigure the data.

A server establishes a secure session with a client device where a private key used in the handshake is stored in a different server. An encrypted connection is established between the first server and the second server. A message is received from the client device that initiates a procedure to establish the secure session between the client device and the first server. As part of this procedure, the first server transmits over the encrypted connection a request to the second server to use the private key. The first server receives, over the encrypted connection, a response to the request that includes a result of the use of the private key. The first server uses the result during the procedure to establish the secure session.

In one implementation, a method for providing end-to-end communication security for a controller area network (CANbus) in an automotive vehicle across which a plurality of electronic control units (ECU) communicate is described. Such an automotive vehicle can include, for example, a car or truck with multiple different ECUs that are each configured to control various aspects of the vehicle's operation, such as an infotainment system, a navigation system, various engine control systems, and/or others.

One disclosed example method includes obtaining a meeting cryptographic key; transmitting, from a client device to a video conference provider, a request to initiate an encrypted video conference, the encrypted video conference including a plurality of participants; distributing the meeting cryptographic key to each participant of the plurality of participants; obtaining a public cryptographic key of a key pair, the key pair including the public cryptographic key and a private cryptographic key; encrypting the meeting cryptographic key using the public cryptographic key; transmitting, from the client device to the video conference provider, a request to record the video conference; encrypting audio and video from a microphone and image sensor of the client device using the meeting cryptographic key; transmitting the encrypted audio and video to the video conference provider; and providing the encrypted meeting cryptographic key to the video conference provider.

A system is provided for exchanging symmetric cryptographic keys using computer network port knocking. The system may receive, from a networked computing device, a first series of packets on a first series of ports which may signify a request to open a secure network connection. Once the secure network connection has been opened, the system may receive a second series of packets on a second series of ports which may be used as seed values to generate a symmetric cryptographic key. Finally, the system may then receive a third series of packets on a third series of ports which may signify the end of the second series of packets (e.g., the seed values). In this way, the system may exchange symmetric key values with the networked computing device which may then be used to open secure communication channels between the system and the computing device.

A system is provided including a first server storing a first data file for a first user, a second server storing a second data file for a second user, a first data card of the first user registered with the first server and locally storing a portion of the first data file, and a second data card of the second user registered with the second server and associated with the second data file. The first data card detects a pairing gesture between the first and second data cards, and in response, establishes a peer-to-peer connection between the data cards. The first data card subsequently detects a transfer gesture between the first and second data cards, and in response, transmits the portion of the first data file from the first data card to the second data card over the peer-to-peer connection.
