    摘要: The present disclosure provides methods, apparatuses, and system for TOTP-based identity authentication. In one aspect, the method includes: obtaining a two-dimensional code from a web end, obtaining, from the two-dimensional code, a key for enabling Time-based One-time Password (TOTP) and a first signature. The first signature is generated by an authentication server by signing the key using a first private key in a first public-private key pair. The method further includes performing signature verification on the first signature based on a first public key in the first public-private key pair, in response to determining the signature verification is successful, performing token calculation based on the key to generate a first token, and sending the first token to a user.

    摘要: A method for issuance of a personalized user device includes initializing a user device to provide an initialized user device, providing device initialization data to an issuer system, wherein the device initialization data comprises a public device key and a public issuer authentication key, calculating a user private key, encrypting the user private key and the public device authentication key with the public device key to provide encrypted data, digitally signing the encrypted data using a private issuer key to provide signed encrypted data, the issuer system providing the encrypted data and the signed encrypted data, injecting said data into the initialized user device to provide the personalized user device, and the personalized user device, conditional on successfully validating the signed encrypted data, decrypting the encrypted data to retrieve the user private key and the public device authentication key.

    摘要: Systems for authenticating a file are disclosed. A system may include one or more physical devices. The one or more physical devices may select, based on an identifier, a subset of data segments of a computer file for generating a first digest with a cryptographic function. The one or more physical devices may also execute the cryptographic function on the selected subset of data segments of the computer file to generate the first digest. Further, the one or more physical devices may generate an authenticator based on the first digest and a private key. The one or more physical devices may further send the computer file, the identifier, and the authenticator to a secure node. Associated methods and non-transitory machine-readable medium are also disclosed.

    摘要: A secure transaction unit includes means for receiving and transmitting one or more tokens to one or more other secure transaction unit in the electronic payment transaction system to cause an exchange of the one or more tokens between secure transaction units in the electronic transaction system. Each token includes at least a monetary value and a private key of a token-individual key pair; means for generating one or more token recovery data sets, each token recovery data set being uniquely assigned to one or more tokens being managed by the secure transaction unit at the time of generating the token recovery data set; means for transmitting the one or more token recovery data sets to a recovery unit, the recovery unit being managed by the participant or by a service provider unit. The invention further relates to a recovery unit in the electronic payment transaction system.
