    摘要： A reach back secure communications terminal includes a modem to satellite interconnect board that captures DTMF tones, demodulates encrypted modem information, and converts both into an ASCII string for presentation to a data port of a satellite phone, allowing out-of-band control of a non-secure satellite system (e.g., AT command control of a data port) by a user on a secure side of an encryption device, by including the ability to interpret control signals and control the satellite system appropriately. A false dial tone is presented to the encryption device, and the data stream coming from the encryption device is monitored for the presence of dual-tone, multi-frequency (DTMF) tones representing control signals, the DTMF tones are converted to ASCII characters, which are in turn received as control signals by the satellite phone, allowing control of the functions of the satellite system directly from the secure side of the encryption device.

    摘要： Methods and systems for slow associated control channel signaling are disclosed. An example method for securing communications in a mobile network disclosed herein comprises transmitting a first variant of a message of a first type on a first slow associated control channel (SACCH) before ciphering is started on the first SACCH, and after ciphering is started on the first SACCH, transmitting a second variant of the message of the first type on the first SACCH, and subsequently transmitting the second variant of the message of the first type on the first SACCH, wherein the subsequently transmitted second variant of the message of the first type is the next transmitted message of the first type on the first SACCH.

    摘要： A mobile satellite communication system is provided to control the transfer of a terminal for a single-hop call from at least one of a clear mode and a ciphered mode with respect to a gateway station to a ciphered mode with respect to a satellite link connecting the terminal with another terminal for a single-hop, terminal-to-terminal call using a cipher key and an encryption algorithm common to the terminal and the other terminal. Frame number offset data, which indicates a mapping delay between received and transmitted time slots at the satellite, is provided to both terminals in a terminal-to-terminal call for ciphering synchronization.

    摘要： Systems, computer program products, and methods are described herein for detecting and preventing malfeasant activity via use of satellite communications. The method includes receiving a transfer request relating to a transfer to be completed associated with a user. The method also includes receiving transfer device data packet(s) from an end-point device via a satellite network. The transfer device data packet(s) includes device information associated with the end-point device. The method further includes determining a malfeasance value based on a comparison of the transfer request and the transfer device data packet(s). The malfeasance value corresponds to a likelihood of a malfeasant activity relating to the transfer request. The method still further includes causing an execution of an elevated action in an instance in which the malfeasance value is equal to or above a malfeasance threshold. The elevated action is an action in which the transfer is delayed or cancelled.

    摘要： Disclosed herein are systems and methods for private communications networks. In various embodiments, a communication system in accordance with the disclosed technology includes a private communications network that has earth stations configured to communicate with a multi-spot beam satellite. The earth stations are communicatively unreachable by communication sources that are remote from the earth stations and that are outside the private communications network, and the earth stations are distributed across geographies covered by different spot beams of the multi-spot beam satellite.
