companies. The FCC recently brought charges against one of AT&T's largest 900
Service customers, and AT&T provided the confidential information necessary in
the prosecution. AT&T also agreed to suspend or disconnect services of
companies violating the commission ban by transmitting obscene or indecent
messages to minors.

Some Hope Left For Victims Of FGD
=================================
US Sprint's famed FGD (Feature Group D) dial-ups and 800 INWATS exchanges may
pose no threat to individuals under switches that do not yet offer equal
access service to alternate long distance carriers. Due to the way Feature
Group D routes its information, the ten-digit originating number of the caller
is not provided when the call is placed from a non-equal access area. The
following was taken from an explanation of US Sprint's 800 INWATS Service.
*************************************************************
CALL DETAIL
*************************************************************
With US Sprint 800 Service, a customer will receive call detail information
for every call on every invoice. The call detail for each call includes:
o Date of call
o Time of call
o The originating city and state
o The ten-digit number of the caller if the call originates in an
equal access area or the NPA of the caller if the non-equal access
area.
o Band into which the call falls
o Duration of the call in minutes
o Cost of the call
This came directly from US Sprint. Do as you choose, but don't depend on
this.

Telenet Bolsters Network With Encryption
========================================
Telenet Communications Corporation strengthened its public data network
recently with the introduction of data encryption capability.
The X.25 Encryption Service provides a type of data security previously
unavailable on any public data network, according to analysts. For Telenet,
the purpose of the offering is "to be more competitive; nobody else does
this," according to Belden Menkus, an independent network security consultant
based in Middleville, NJ.
The service is aimed at users transmitting proprietary information between
host computers, such as insurance or fund-transfer applications. It is priced
at $200 per month per host computer connection. Both the confidentiality and
integrity of the data can be protected via encryption.
The scheme provides end-to-end data encryption, an alternative method whereby
data is decrypted and recrypted at each node in the network. "This is a
recognition that end-to-end encryption is really preferable to link
encryption," Menkus said.
The service is available over both dial-up and leased lines, and it supports
both synchronous and asynchronous traffic at speeds up to 9.6K BPS.
Telenet has approved one particular data encryption device for use with the
service, The Cipher X 5000, from Technical Communications Corporation (TCC), a
Concord, Massachusetts based vendor. TCC "has been around the data encryption
business for quite a while," Menkus said.
The Cipher X implements the National Bureau of Standards' Data Encryption
Standard (DES). DES is an algorithm manipulated by a secret 56 bit key.
Computers protected with the device can only be accessed by users with a
matching key.
The data encryptor is installed at user sites between the host computer and
the PAD (Packet Assembler/Disassembler).
Installation of the TCC device does not affect the user's ability to send
non-encrypted data, according to Telenet. By maintaining a table of network
addresses that require encryption, the device decides whether or not to
encrypt each transmission.
