Abstract: There is provided a packet transmission control device including a packet interval adjustment unit that adjusts packet intervals of a plurality of packets, a packet replication unit that replicates the plurality of packets whose packet intervals are adjusted by the packet interval adjustment unit to generate a plurality of packet groups, and a destination assignment unit that assigns different destination information pieces to the respective plurality of packet groups generated by the packet replication unit.

Abstract: In an information communication system, information communication devices exchange an IP packet over IP networks. When performing a predetermined packet exchanging procedure in which the number of router hops is limited to a predetermined control value or less, each of the information communication devices monitors Time-To-Live values designated in the headers of IP packets received over a period of time from the start of the predetermined packet exchanging procedure to immediately before the end of the predetermined packet exchanging procedure to continuously update the maximum Time-To-Live value of the monitored Time-To-Live values, and checks whether the maximum Time-To-Live value does not exceed the control value.

Abstract: An information processing apparatus for processing encrypted data input as a byte stream with dynamically changing decryption keys includes the following elements. An encrypted data receiving section receives encrypted data input as a byte stream, identifies a range of data that is decrypted using an identical key as a unit of decryption, extracts information necessary for decryption from the byte stream, and outputs encrypted data sets in which the extracted information is added to segments of the encrypted data. An encrypted data decrypting section sequentially decrypts the encrypted data by queuing the encrypted data sets while distributing the encrypted data sets to generate plaintext data. A plaintext processing section processes the generated plaintext data.
