    Abstract: An apparatus and method for reconstructing missing data using cross-parity stripes on a storage medium is provided. The apparatus and method may operate on data symbols having sizes greater than a data bit. The apparatus and method makes use of a plurality of parity stripes for reconstructing missing data stripes. The parity symbol values in the parity sripes are used as a basis for determining the value of the missing data symbol in a data stripe. A correction matrix is shifted along the data stripes, correcting missing data symbols as it is shifted. The correction is performed from the outside data stripes towards the inner data stripes to thereby use previously reconstructed data symbols to reconstruct other missing data symbols.

    Abstract: A policy caching method (400) for use in a communication device is provided. The communication device determines which instance of protocol data unit (PDU) network policy from a plurality of policies is to be applied to related-received PDUs based on contents of one of the related-received PDUs (406). Subsequently, policy identification information identifying the instance PDU policy is cached (408) for future application to other of the related-received PDUs (410). Also, a communication device which implements this policy caching method is provided.

    Abstract: A customer making a credit card transaction inserts their smart card into a card reader attached to the merchant's system. The card reader activates the customer's card and passes certain merchant information. The merchant's system then requests a "billing digest" from the customer's card. The billing digest is returned to the merchant's card reader that forwards it (and the transaction information which includes customer information and merchant information) to the corresponding credit card issuer, which maintains the customer's credit card account. In one embodiment, the customer information and the merchant information are encrypted. Upon receiving the billing digest, transaction information is decrypted if necessary and the credit card issuer looks up the customer's master key using the customer's account number. The credit card issuer then uses the transaction information to re-compute the billing digest (an authentication billing digest) and compares this new value with the billing digest submitted by the merchant. If authentic, the billing digest and authentication billing digest values are equivalent, then funds are transferred and an acceptance notification is returned to the merchant. If not authentic, a denial notification is returned to the merchant. Security is further enhanced by utilizing a unique reference for each transaction in the unique customer information used for creating the billing digest.

    Abstract: Initially, a key range variable is created by concatenating the card group value, card number and reference number for an encryption key to be generated. A hashing algorithm generates an encryption key from a master key and the variable key range variable. The encryption key and the key range variable are output to the caller who requested the key. The encryption key is used to encrypt the information, while the variable key range is stored with the encrypted data. Generation of a decryption key requires a user call for a decryption key and includes the key range variable from the encrypted data. A hashing algorithm generates a decryption key from the master key and the key range variable. The decryption key is used to decrypt the information.
