Abstract: In an example, a computing device is described. The computing device comprises a communication interface and a processor. The processor is to determine whether a signature, produced by a signer, is derived from a free state under a stateful signature scheme. The free state is a state that has not been used as an input to generate a signing key. The signature is encrypted by the signer. The processor is further to, in response to determining that the signature is derived from a free state, decrypt the encrypted signature. The processor is further to transmit the decrypted signature to a recipient via the communication interface.

Abstract: A system, comprising an authentication module to generate a challenge to authenticate a user, the challenge to be distributed to members of a set of verifying parties; and grant the user access to a resource upon receiving an authenticating response to the challenge; and a combiner module to receive partial responses from members of the set of verifying parties upon verification of the user by each member, the verification made using a provided contextual identifier of the user; based on the partial responses reaching a threshold number of responses, combine the partial responses to obtain a combined response, and provide the combined response to the authentication module as an authenticating response to the challenge.

Abstract: In an example, an apparatus is described. The apparatus comprises a processor to interface with a computing system and a memory device comprising a set of logical cells. A logical cell of the set of logical cells indicates a data value by an amount of charge stored in a physical cell of the logical cell. Charge leakage between the physical cell and an adjacent physical cell of the logical cell is to occur at a rate that at least partially depends on a relative amount of charge stored in the physical cell and the adjacent physical cell. The apparatus further comprises a machine-readable medium storing instructions readable and executable by the processor to cause the processor to process a request issued via the computing system for the processor to cause a memory operation to be performed in the memory device.

Abstract: In an example, an apparatus is described. The apparatus comprises a memory device comprising a set of logical cells. A logical cell of the set of logical cells indicates a data value by an amount of charge stored in a physical cell of the logical cell. Charge leakage between the physical cell and an adjacent physical cell of the logical cell is to occur at a rate that at least partially depends on a relative amount of charge stored in the physical cell and the adjacent physical cell. A set of data values indicated by the set of logical cells is to change over time due to the charge leakage. The set of data values indicated by the set of logical cells is representative of information that is valid over an estimated period of time, which is based on the rate of charge leakage.

Abstract: In an example, a method includes receiving a signed message generated by a computing device associated with a private key and a public key. The signed message includes an input message signed with the private key. The method further includes generating, using processing circuitry, a candidate public key based on the input message and the signed message using a public key recovery procedure. The method further includes determining the public key associated with the computing device based on an indication as to whether or not the candidate public key corresponds to the public key associated with the computing device.

Abstract: A method of operating a service provider server and a computing device to provide anonymous service access. For the service provider server, the method comprises: receiving a service message from a computing device; and determining whether to send a service response message, and if so sending a service response message. The service message includes a pseudonym associated with the computing device, service data and a signature on the pseudonym generated by either the service provider server or an identity manager. The service response message is broadcast by the service provider server or transmitted to the identity manager.

Abstract: An apparatus is disclosed. The apparatus may comprise a storage medium to store: a first data structure to receive a first plurality of numerical identifiers, each numerical identifier of the first plurality of numerical identifiers corresponding to a respective signal received during a first defined time interval; and a second data structure to receive a second plurality of numerical identifiers, each numerical identifier of the second plurality of numerical identifiers corresponding to a respective signal received during a second defined time interval, wherein the first defined time interval is earlier in time than the second defined time interval. The apparatus may comprise a processor. Upon expiry of a defined time period, the processor is to: delete the first data structure; and provide a third data structure to receive a third plurality of numerical identifiers, each numerical identifier of the third plurality of numerical identifiers corresponding to a respective signal received during a third defined time interval occurring after the second defined time interval. A method and a machine-readable medium are also disclosed.
