    摘要： Methods and systems for providing confidentiality of communications sent via a network that is efficient, easy to implement, and does not require significant key management. The identity of each node of the routing path of a communication is encrypted utilizing an identity-based encryption scheme. This allows each node of the routing path to decrypt only those portions of the routing path necessary to send the communication to the next node. Thus, each node will only know the immediate previous node from which the communication came, and the next node to which the communication is to be sent. The remainder of the routing path of the communication, along with the original sender and intended recipient, remain confidential from any intermediate nodes in the routing path. Use of the identity-based encryption scheme removes the need for significant key management to maintain the encryption/decryption keys.

    摘要： Methods and systems for verification of indicia that do not require key management systems, and in which revocation of key pairs is easily performed without adding costs to the verification process are provided. Indicia are generated and authenticated utilizing an identity-based encryption (IBE) scheme. A key generating authority generates a private key for a PSD, distributes the private key securely to the PSD, and provides public information for use by a verification service when verifying cryptographic digital signatures generated with the private key. The corresponding public key is a string consisting of PSD information that is provided as part of the indicium. The verification service can verify the signature of each indicium by obtaining the public key string from the indicium, and utilizing the key generating authority's public information.

    摘要： Methods and systems that prevent completion of postdated financial transactions until the specified future date is provided. A portion of the information necessary to complete a financial transaction is encrypted utilizing an identity-based encryption (IBE) scheme. The encryption key used to encrypt the information is associated with the date on which the transaction is authorized to be completed. The encrypted information is provided to the payee. The issuing bank provides a daily decryption key that allows decryption of information encrypted using the key associated with the corresponding date. Thus, only when the maturity date of the transaction has arrived will the payee or depositing bank be able to obtain the decryption key that will decrypt the encrypted information necessary to complete the transaction. Since the encrypted information can not be decrypted until the date associated with the encryption key, the financial transaction can not be completed until such date.

    摘要： A signature scheme is provided in which a message is divided in to a first portion which is hidden and is recovered during verification, and a second portion which is visible and is required as input to the verification algorithm. A first signature component is generated by encrypting the first portion alone. An intermediate component is formed by combining the first component and the visible portion and cryptographically hashing them. A second signature component is then formed using the intermediate component and the signature comprises the first and second components with the visible portion. A verification of the signature combines a first component derived only from the hidden portion of the message with the visible portion and produces a hash of the combination. The computed hash is used together with publicly available information to generate a bit string corresponding to the hidden portion. If the required redundancy is present the signature is accepted and the message reconstructed from the recovered bit string and the visible portion.

    摘要翻译： 提供一种签名方案，其中消息被分成隐藏的第一部分，并且在验证期间被恢复，并且第二部分是可见的并且被要求作为验证算法的输入。 通过单独加密第一部分来产生第一签名组件。 通过组合第一组件和可见部分并对其进行密码散列来形成中间组件。 然后使用中间部件形成第二签名部件，并且签名包括具有可见部分的第一和第二部件。 签名的验证将仅从消息的隐藏部分导出的第一组件与可见部分组合，并产生组合的散列。 所计算的散列与公开可用的信息一起使用以产生对应于隐藏部分的位串。 如果存在所需的冗余，则签名被接受，并且从恢复的位串和可见部分重建消息。
