    Abstract: Systems and techniques are provided for delegated attestation. For example, a process by an apparatus can include receiving an indication to attest to a property of a target device; generating a measurement associated with the property of the target device; generating data regarding an integrity of the apparatus; generating attestation data, the attestation data including information associated with the generated measurement and the generated data regarding the integrity of the apparatus; and transmitting the attestation data to a verifier device.

    Abstract: The present invention relates to a method for a secondary station to obtain a time reference in a cellular network in order to verify the freshness of received messages. The method comprises the steps of receiving a plurality of system information, SI, messages from a plurality of primary stations, said SI messages including each a respective time reference information related to the corresponding primary station, checking the validity of a received signature for each of the primary stations, checking a cell identifier for each of the primary stations with a valid signature, and ignoring time reference information from primary stations with a cell identifier being identical to another primary station and having an earlier value than the one from the other primary station, and deducing a local time reference from one or more of the time reference information originating from primary stations with a valid signature.

    Abstract: An authorization device obtains a registration request associated with an end device, the registration request including a new randomized media access control (MAC) address associated with the end device; determines whether the end device is authorized to use the new randomized MAC address; transmits a message to the end device with a first randomly generated number when it is determined that the end device is authorized to use the new randomized MAC address; obtains integrity information associated with the end device, the first integrity information being computed based on the first randomly generated number; transmits a request to a validation system to validate the end device based on the first integrity information; obtains an indication that the end device is validated; determines policies associated with the end device when it is determined that the end device is validated; and applies the policies to the end device.

    Abstract: Various embodiments described herein are directed towards authenticating calls by using one or more keys associated with a specific user. In examples, the user is the sender of a call. In various embodiments, when a call is made, an identifying payload is encrypted using a private key associated with the user. The encrypted identifying payload is appended to the call data stream. The identifying payload may be decrypted with a public key. In embodiments, the identifying payload may be verified. In various embodiments, further authentication methods may be performed by using an object such as a contactless card to provide one or more components of the identifying payload and/or keys. In embodiments, a connection may be made between the sender and the intended recipient of a call based on the verification of the identifying payload.
