    摘要: Elliptic curve hash functions are provided which do not require a pre-existing hash function, such as that required by the MuHash. The elliptic curve hash functions can be built from scratch and are collision free and can be incremental. In one embodiment, rather than a pre-existing hash function, the identity function with padding is used; and in another embodiment, rather than a pre-existing hash function, a block cipher with a fixed non-secret key is used.

    摘要: An envelope used in voting by mail includes a signature area on which the signature is affixed and a concealing portion structured to cover the signature area thereby concealing the signature. The concealing portion includes a concealing layer that is preferably positioned on top of a protective layer. The protective layer is positioned between the signature area and the concealing layer when the concealing portion covers the signature area. The concealing layer is formed from a material that is normally opaque but becomes at least partially transparent when one or more chemicals are applied to the concealing layer. The protective layer protects the signature from the one or more chemicals since the protective layer is impermeable to the one or more chemicals.

    摘要: A vote-by-mail return envelope that includes a pouch portion for containing the ballot and a stub portion on which the voter applies his/her signature and method for processing are provided. Each portion of the envelope contains a respective barcode that identifies the respective portion. When the envelope is received at the vote-counting location, the stub is separated from the pouch, thereby separating the voter's signature, name, etc. from the ballot. The signature is then verified from the stub, and subsequent processing of the pouch uses the pouch barcode identifier as a link to the stub barcode identifier and/or to the result of the signature verification, to determine whether the ballot in the pouch is eligible for counting or whether some remedial procedure is necessary.

    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: Print quality is ensured in a postage meter system employing an ink system and having settable modes of printing operation by detecting the type of ink system employed in the postage meter system, setting a first mode of printing operation for the postage meter system when the detected ink system is of a first type and setting a second mode of printing operation for the postage meter system when the detected ink system is of a second type. The detected information may be communicated to a data center to obtain modes of operation for the postage meter system and other corrective actions may be implemented. The method and system are applicable to other consumable item systems employing various types of consumable items.

    摘要: A monitoring system for a corporate network includes a client that exchanges information with a target server to establish an SSL communication channel through which cryptographically protected data is exchanged between the client and the target server using an SSL protocol and a monitoring server through which the cryptographically protected data is routed as part of its exchange between the client and the target server. The client sends enabling data to the monitoring server that enables the monitoring server to read the cryptographically protected data received at the monitoring server as decoded cryptographically protected data. The monitoring server also analyzes the decoded cryptographically protected data to determine if it is suspect data, and at times when the monitoring data determines that the decoded cryptographically protected data is suspect data the monitoring server prevents the transmission of the cryptographically protected data between the client and the target server.

    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: A system and method are described for establishing and managing a vendor inventory of emergency business supplies for a business. The vendor is compensated for costs of maintaining the inventory. The business supplies are released periodically, for discount sale, after they have been in the vendor inventory for a period of time expiring when a release condition occurs. The vendor inventory is then restocked, and the vendor is compensated at least partially for the discount provided in the discount sale.
