    Abstract: An authentication method of a first module by a second module includes the steps of generating a first random datum by the second module to be sent to the first module, generating a first number by the first module starting from the first datum and by way of a private key, and generating a second number by the second module to be compared with the first number, so as to authenticate the first module. The step of generating the second number is performed starting from public parameters and is independent of the step of generating the first number.

    Abstract: An example method for managing data in accordance with aspects of the present disclosure includes receiving from a user in the computer network environment a policy about how a piece of data should be treated, an encryption of the piece of data, a signature of a cryptographic hash of the policy and a cryptographic key, requesting from a trust authority the cryptographic key to access the piece of data, transmitting an encryption of at least one share to the trust authority, wherein the at least one share is created by and received from the trust authority, receiving from the trust authority the cryptographic key, wherein the cryptographic key is recreated by a combiner using a subset of the at least one share, shares associated with the trust authority and shares associated with the combiner, and decrypting the encryption of the piece of data using the recreated cryptographic key.

    Abstract: An electronic device for management of cryptographic keys, and a corresponding method implemented in a computing device comprising a physical processor, transmit feature data of the device to a key generation module, wherein the feature data comprises information corresponding to an identifier or an attribute of the device, and receive, by the device from the key generation module, a digital signature of the transmitted feature data. The device installs the received digital signature as a cryptographic private key for communication, and performs a cryptographic operation using the installed digital signature as the cryptographic private key.
