Patent number: 9942033Abstract: A system for performing encryption and/or decryption may include a parent cryptographic device. The parent cryptographic device may be configured to receive a first cryptographic key. The parent cryptographic device may be configured to determine one or more session keys based on the first cryptographic key and/or internally generated random data bits. The parent cryptographic device may be configured to insert the one or more session keys onto one or more child cryptographic devices that are operably connected to the parent cryptographic device. The one or more child cryptographic devices may be configured to receive the one or more session keys from the parent cryptographic device, and perform one or more of encryption or decryption of communications exchanged with another child cryptographic device of the one or more child cryptographic devices. The one or more child cryptographic devices may perform encryption/decryption after separation from the parent cryptographic device.Type: GrantFiled: October 31, 2016Date of Patent: April 10, 2018Assignee: L3 TECHNOLOGIES, INC.Inventors: Richard Norman Winslow, Frank A.

Publication number: 20040170222Abstract: Apparatus and methods for determining an operational mode of a far-end modem are disclosed. Where the multimode modem is a call initiator, a method according to the invention includes transmitting a V.8 ANSam tone to the far-end modem, receiving a response signal from the far-end modem, and determining from the response signal whether the far-end modem is a commercial modem or a secure modem. Where the multimode modem is a call responder, a method according to the invention includes transmitting to the far-end modem a P1800 Hz tone with phase reversals, receiving a response signal from the far-end modem, and determining from the response signal whether the far-end modem is a commercial modem or a secure modem.Type: ApplicationFiled: March 11, 2004Publication date: September 2, 2004Applicant: L-3 Communications CorporationInventor: Frank A.

Patent number: 6266418Abstract: An encryption device for a telephone having a handset and a base unit is disclosed. The device includes a handset interface, a first converter, an encryption processor, a second converter, and a host interface. The handset interface receives analog output signals from the handset. The first converter converts the analog output signals into digital output signals. The encryption processor includes a compressor, a key manager, an encryptor, and a modulator. The key manager generates key material for encrypting the digital output signals. The compressor compresses the digital output signals, the encryptor encrypts the digital output signals based on the key material, and the modulator modulates the encrypted digital output signals. The second converter converts the encrypted digital output signals into encrypted analog output signals. The host interface receives the encrypted analog output signals from the encryption processor, and forwards the encrypted analog output signals to the base unit.Type: GrantFiled: October 28, 1999Date of Patent: July 24, 2001Assignee: L3-Communications CorporationInventors: Matthew Carter, Frank Costantini, Moishe Kleidermacher, Ellwood McGrogan, Ronald Paraggio
