Abstract
An information processing apparatus which makes it possible to store encrypted data of packets in a decrypted state, and improve the efficiency of data analysis. A network interface receives encrypted data which has been encrypted, and data which has not been encrypted, from a network. A HDD stores received data. A IPSec module is operable when an item of the received is an item of the encrypted data, to decrypt the item of the encrypted data. A packet acquisition sub application searches the data stored in HDD for an item of the encrypted data corresponding to an decrypted item of data. The packet acquisition sub application updates the item of the received encrypted data based on the decrypted item of the data.
