    摘要: A method of updating a data entry stored on a data storage unit, the data entry including data elements that are unique to the data storage unit and the data entry, may begin with generating, at the data storage unit, an update request that includes the data entry for transmission to an authority authorized to update the data entry. The authority then extracts extracting at the authority the unique data elements from the update request and verifies the authenticity of the data storage unit and data entry from the unique data elements. The authority then generates an updated data entry including a further data element unique to the updated data entry and derived from the updated data. The authority then transmits the updated data entry to the data storage unit. The method may then include storing the updated data entry on the data storage unit.

    摘要: An authentication method is provided between entities (10A; 10B) having matching one-time pads each with multiple OTP blocks. From the standpoint of a first one (10A) of the entities, the method involves sending (20S) a challenge that it has generated (20) by subjecting a first OTP block to a randomly-selected member of a first family of hashing functions. Each member of the first hashing-function family is associated with a respective member of a second family of hashing functions. On receiving back a response, the first entity (10A) tests (26) whether the response originates from the second entity (10B) by seeking a match between the response and a reference value generated (25) by subjecting a predetermined said OTP block to the member of the second hashing-function family that is associated with the member of the first hashing-function family used to generate the challenge.

    摘要: A quantum key distribution (QKD) method involves the sending of random data from a QKD transmitter to a QKD receiver over a quantum signal channel, and the QKD transmitter and receiver respectively processing the data transmitted and received over the quantum signal channel in order to seek to derive a common random data set. This processing is effected with the aid of messages exchanged between QKD transmitter and receiver over an insecure classical communication channel. The processing concludes with a check, effected by an exchange of authenticated messages over the classical communication channel, that the QKD transmitter and receiver have derived the same random data set. At least some of the other messages exchanged during processing are exchanged without authentication and integrity checking. A QKD transmitter and QKD receiver are also disclosed.

    摘要: A cryptographic method and apparatus is provided in which an identifier-based encryption process is used to encrypt a message with an identifier string that specifies conditions to be checked by a trusted entity before providing a decrypted form of the encrypted message, or enabling its decryption. A further trusted entity is used to verify the identity of the message sender as indicated by a further identifier string, and to provide the sender with a secret key that the sender uses to generate complimentary signature components. These signature components are sent along with the encrypted message and are used, along with other data including the first identifier string and a public key of the further trusted entity, to authenticate the identity of the message sender.

    摘要: First data is encrypted by a first party using an encryption key string formed using at least a hash value of the first data, this hash value being either in clear or in an encrypted form enabling its recovery in clear by a trusted party. The encrypted first data and the encryption key string are made available to a second party which forwards the encryption key string to the trusted party. The trusted party carries out at least one check on the basis of data contained in the encryption key string and, if the checks are satisfactory, provides a decryption key to the second party. Where the encryption key string comprises the hash value of the first data in encrypted form, the trusted party will typically decrypt the hash value and pass it to the second party to enable the latter to check the integrity of the first data.
