Abstract: Methods that can verify a password utilizing commitments are provided. One method includes receiving from a client device and storing, by a processor, an initial commitment representing a password for a user account without storing the actual password on the apparatus, receiving, from the client device, a subsequent commitment, and verifying that the subsequent commitment represents the password for the user account based on a difference between the initial commitment and the subsequent commitment. Systems and apparatus that can include, perform, and/or implement the methods are also provided.

Abstract: A system includes a binary tree having leaf hashes. The leaf hashes include a device privacy protected index and a set of zero-knowledge commitments relating to a computer device. The system calculates the device privacy protected index using a verifiable random function such that a device entity path in the binary tree cannot reveal any information about any other device in the binary tree, and associates the set of zero-knowledge commitments with the device privacy protected index. The system then generates a privacy-protected attestation for the computer device using the device privacy protected index and the set of zero-knowledge commitments.

Other aspects are described and claimed.

Abstract: An approach is provided that receives a password that corresponds to a user identifier. A number of hashing algorithms are retrieved with the specific hashing algorithms that are retrieved being based on the received user identifier. The password is hashed using each of retrieved hashing algorithms resulting in a number of hash results. The hash results are combined with the combining of the hash result eventually resulting in a combined hash result. An expected hash result that corresponds to the user identifier is retrieved and compared to the combined hash result. The password is verified based on the results of the comparison.

Abstract: An approach is provided that uses multiple hashing algorithms to verify a password. The approach receives a password that corresponds to a user identifier. A set of hashing algorithms are retrieved with the retrieved set based on the received user identifier so that different user identifiers utilize different sets of hashing algorithms. Hashing the password using each of the hashing algorithms included in the set of algorithms with the hashing resulting in a hash result. An expected hash result that corresponds to the user identifier is retrieved and the approach then verifies the received password by comparing the hash result to the first expected hash result.

Abstract: One or more device(s) is identified for which ownership of the device(s) is to be transferred from an identified transferor system to an identified transferee system. An ephemeral device transfer token is generated for the transferor using an elliptic-curve Diffie-Hellman cryptographic function, wherein the ephemeral device transfer token is only valid over a limited period of time to authorize a transfer of ownership of the device from the transferor to the transferee. The transferor then delivers the ephemeral device transfer token to the transferee. A device ownership record may be modified to transfer ownership of the device from the transferor to the transferee in response to receiving the ephemeral device transfer token from the transferee during the limited time period.

Abstract: For secure attribute verification, a processor generates a plurality of hashes of a seed and a previous public group index. The processor further iteratively generates a public group index for each hash. The processor generates a one-time user identifier expressed as a hash chain of identifiers each based on one of the public group indexes. The processor verifies user attributes from the one-time user identifier.
