A method at a first domain for obtaining at least one insight from a second domain, the method including registering an application with an anchor in the first domain; providing, from the anchor to the application, a first message signed by the anchor; sending, from the first domain to a network domain, the signed message; receiving, from the network domain, at least one signed token, each of the at least one signed token being for a synthetic sensor on the second domain, where the synthetic sensor provides an insight; sending a request message to the second domain, the request message requesting the insight and including the at least one token; and receiving the insight from a synthetic sensor associated with the at least one token.

A method of communicating in a secure communication system, comprises the steps of assembling a message at a sender, then determining a security level, and including an indication of the security level in a header of the message. The message is then sent to a recipient.

Systems and methods for geofence information delivery are disclosed. A multiplicity of devices constructed and configured in network communication in a region of interest via a peer-to-peer network. The multiplicity of devices store cached geofence information for the region of interest. The multiplicity of devices on the peer-to-peer network are operable to convert between an IP address and a geographic location. Each of the multiplicity of devices is operable to query peer devices on the peer-to-peer network for geofences associated with an IP address or a geographic location. At least one peer device is operable to deliver one or more geofences associated with the IP address to the querying device via zero-configuration networking or web service.

A computer implemented method for providing communication between a secured client computer and a remote computer. There is provided a client computer that includes peripheral components. Each peripheral component is configured, by a processor, to process a corresponding peripheral component data of a data type that is not compatible with peripheral component data types processed by a processor of other peripheral components. The processor of each peripheral component is further configured to code the corresponding data of the specified data type. Each peripheral component is configured, by the processor, to establish a secured peer-to-peer communication channel between the peripheral component and the remote computer that is authorized to communicate with the client computer, and is further configured to code data that is communicated between the authorized remote computer and the peripheral component through the secured communication channel. The coded data being indecryptable by the processors of other of the peripheral components.

The disclosure relates to improvements in secure channel establishment. In some aspects, the techniques described herein relate to a method including: issuing, by a client device to a server, a request to establish a secure connection; receiving, by the client device, a response to the request to establish a secure connection from the server, the response including a digital certificate associated with a public key stored by the server, the public key used to establish a symmetric key; validating, by the client device, the digital certificate; and computing, by the client device, a shared secret using the public key stored by the server and a private key generated by the client device.

A user device having a security context with a first network based on a first key may establish a security context with a second network. In a method, the user device may generate a key identifier based on the first key and a network identifier of the second network. The user device may forward the key identifier to the second network for forwarding to the first network by the second network to enable the first network to identify the first key at the first network. The user device may receive a key count from the second network. The key count may be associated with a second key forwarded to the second network from the first network. The user device may generate the second key based on the first key and the received key count thereby establishing a security context between the second network and the user device.

A method and an apparatus for controlling a data access right are disclosed. The method includes: receiving, by a first proxy node, a first request message from a request node, where the first request message includes an identity of the request node and an identifier of to-be-accessed data; determining a first encrypted ciphertext on a blockchain based on the identifier; determining, based on the identity, whether the request node has a right to read the first encrypted ciphertext; and if yes, initiating a right verification request for the request node to at least one second proxy node, and determining, based on a feedback result of the at least one second proxy node, provisioning of the first encrypted ciphertext. A proxy node is added to the blockchain network, so that a data source can freely grant or revoke the right of the request node without modifying a ciphertext, ensuring information security.

Systems and methods provide a transient component limited access to data in a composition. One method includes receiving a request for the transient component to access data in the composition. The composition may include permanent components operable to utilize encryption keys generated at selected intervals from a seed value shared by the permanent components. The encryption keys utilized by the permanent components at each selected interval may be identical to one another. The method also includes generating a set of encryption keys from the seed value for a specified period of time. The set of encryption keys may be identical to the encryption keys to be utilized by the permanent components at the selected intervals to occur during the specified period of time. The method further includes granting the transient component access to data in the composition for the specified period of time via the set of encryption keys.

A path is secured from one node to another node of the computing environment. The one node obtains a first encryption key and a second encryption key. A shared key is obtained by the one node from a key server, and the shared key is used to encrypt a message. The encrypted message includes the first encryption key and the second encryption key. The encrypted message and an identifier of the shared key is sent from the one node to the other node, and a response message is received by the one node. The response message at least provides an indication that the other node received the encrypted message and obtained the shared key.

Zero round trip secure communications are implemented based on noisy secrets with a polynomial secret sharing scheme. A sender identifies two negotiated noisy secrets associated with an encrypted message to send to a receiver system. The sender utilizes a first negotiated noisy secret for sub-key selection, and generates a secret polynomial using Shamir's polynomial-based secret sharing scheme with N positive integer points and a message key as a secret. The sender divides the first negotiated noisy secret into a plurality of sub-keys, and divides a second negotiated noisy secret into test blocks of a length equivalent to a length of a sub-key. The sender utilizes each of the plurality sub-keys for encrypting a corresponding test block along with one unique point of the secret polynomial. Moreover, the sender sends all encrypted test blocks and corresponding encrypted points of the secret polynomial to the receiver with the encrypted message.
