摘要： An apparatus includes a tokenizer and a validator. The tokenizer divides a file into first, second, and third portions. The tokenizer also encrypts the first, second, and third portions using a first key to produce first, second, and third tokens. The validator receives a fourth token with a signature of a first user and receives a fifth token with a signature of a second user. The validator also combines the first token, the fourth token, and the fifth token to produce a second key and determines whether the second key matches the first key. If the second key does not match the first key, the validator communicates an alert indicating that the first key does not match the second key. If the second key does match the first key, the validator decrypts first, fourth, and fifth tokens to reproduce the file.

摘要： Disclosed embodiments include techniques to increase the probability that network validators will include a specific transaction in a target block of a blockchain. The method includes creating and signing in real-time a transaction and loading copies of the transaction at agent nodes connected to a network of peer nodes. An agent node can obtain an indication of an opportunity to write the transaction to a target block. The method can further include broadcasting the transaction to the network of peer nodes based on the obtained indication of the opportunity to write the transaction, to improve a probability of having the transaction written to the target block.

摘要： An attribute-based digital signature system comprises a signature generation unit (1) for signing a message (m) by generating a signature (σ) based on a user secret key (SK) associated with a set of user attributes, wherein the signature generation unit (1) is arranged for combining the user secret key (SK) with revocation data (R) to form at least part of the signature (σ), wherein the revocation data (R) complements respective ones of a plurality of valid user secret keys and wherein the revocation data (R) prevents a revoked user secret key (SK) from being used to validly sign a message (m) with the set of user attributes. The system further comprises a revocation unit (2) for selectively removing at least part of the signing capability of a to-be-revoked user secret key (SK), by generating updated revocation data (R), wherein the updated revocation data (R) is based on at least part of the to-be-revoked user secret key (SK). A plurality of attribute authorities 301 may independently issue cryptographic keys.

摘要： Exemplary embodiments provide various techniques for managing groups of authenticated entities. In one exemplary computer-implemented method, an entity accesses a group roster that includes a first group identifier identifying a first group, a first group digital certificate associated with the first group, and a first entity identifier identifying the entity being a member of the first group. The entity also receives a request to update the group roster. Here, the request includes a second group identifier identifying a second group and a second group digital certificate associated with the second group. In response to the request, the entity replaces the first group identifier in the group roster with the second group identifier. Additionally, in response to the request, the entity replaces the first group digital certificate with the second group digital certificate. The replacements change a membership of the entity from the first group to the second group.

摘要： The invention relates to a method and system for managing and checking different identity data relating to a person. According to the invention, a derived-identity management server generates for the person at least part of the identity data with which said person can be authenticated in relation to a service provider for the derived-identity domain, on the basis of information derived from identity data from parent domains. The identity data generation processing ensures that no link can be established from two authentications in two separate domains in the absence of link information. If necessary, said link information is transmitted by a parent domain to a derived-identity server so that the latter establishes the link between the identity data of the derived-identity domain and the identity data of the parent domain, e.g. for the cascade revocation of a person from various domains.
