Decryption uses the number of pseudo-random numbers that need to be generated by the APRNG to match the ASCII codes of the plaintext characters. Variations to the starting and reset points for the counter are also presented for improving performance when cipher-characters are lost and for avoiding increasing the size of the ciphertext as opposed to the basic methodology. |

Quantity sensing storage system
A quantity sensing storage device enables automatic ordering of a product using an ordering engine that monitors quantity signals generated by a quantity sensor that is configured to provide the quantity signals based on a quantity of a first set of a product stored at the quantity sensing storage device. Base on the quantity of the first set, the ordering engine determines whether an order threshold has been satisfied. The quantity sensing storage device automatically provides instructions to a service provider device via a wireless communication subsystem to order a second set of the product in response to determining that the order threshold has been satisfied. The ordering engine continuously updates the order threshold such that when the second set of the product is received by a user of the quantity sensing storage device, an optimal portion of the first set of the product remains stored in the storage enclosure. |
