A method for authenticating an entity at a first data resource, the method comprising the steps of: sending a first request token from the entity () to a token distribution unit () to request a first one-way authentication token, the first request token being a function of authentication information provided by the entity (); sending the first one-way authentication token from the token distribution unit () to the entity (); sending the first one-way authentication token from the entity () to the first data resource () to authenticate the entity () at the first data resource (); sending the first one-way authentication token from the first data resource () to the token distribution unit () to validate the first one-way token; and invalidating the first one-way token.

Methods and apparatuses for validating a message with a signature. The method may include receiving the message with the signature and carrying out an integrated validation and storing process. The signature may be validated based on a validation algorithm and a key. The received message may be stored in a database. A method for generating a signature for a message may include carrying out an integrated receiving and generating process. The message to be sent may be received and the signature may be generated based on a signing algorithm and a key. The message may be sent with the signature.
