A form of encryption that utilizes a unique pair of keys, one (the "public key") being openly known, and the other (the "private key",) being known only to the recipient of an encrypted message. Note 1: At the recipient's discretion, the public key is made available to those who may have occasion to send an encrypted message to that recipient. The sender uses the recipient's public key to encrypt a message. The encrypted message, which cannot be decrypted by means of the public key, is then delivered by conventional means to the recipient, who uses the matching private key to decrypt the message. Note 2: Public-key encryption can also be used to add a digital signature to publicly posted electronic messages. The poster of an electronic message feeds the text of the message into the encryption program, along with the poster's private key. A unique block of text (the digital signature) is generated and attached to the end of the message. Any other reader of the message can use the poster's public key to analyze the message text and the signature block. The encryption software will indicate whether or not the message text matches the digital signature. Note 3: Users of public-key encryption systems may register their public keys in several public databases.

A form of HTML used to create Web-page content that, as perceived by the viewer, appears to change each time it is viewed, without further interaction with the server. Note: The Web-page content may use any of several technologies including CGI (computer graphics interface) scripts.
Industry:Telecommunications
A form of interactive online typewritten communication that allows participants ("members") to engage in text-message conferencing, via real-time computer networking over designated communications facilities ("chat rooms",) without storing the messages. Note: Participants' messages are instantaneously relayed to all other participants logged into the chat room; in turn, their replies are likewise instantaneously relayed to the originator and all other participants.
Industry:Telecommunications
A form of notification information that consists of the documentation of the actual sequence of intermediate networks traversed by a signaling message. The documentation of the sequence of networks traversed may also include the origination and destination networks. The documentation that the message traversed a given network is performed by that network itself. Intermediate networks that are not ISNI-capable are not identified. ISNI identification information can be used to force a return error message, destined for the originating SEP, to transit the same intermediate network (s) as the original message.
Industry:Telecommunications
A form of short-term communications security applied to the electromagnetic or acoustic transmission of unclassified information that warrants a degree of protection against simple analysis and easy exploitation but that does not warrant protection to the extent needed for security of classified information.
Industry:Telecommunications
A form of telecommunication for the transmission of transient images of fixed or moving objects. Note 1: The picture signal is usually accompanied by the sound signal. Note 2: In North America, TV signals are generated, transmitted, received, and displayed in accordance with the NTSC standard.
Industry:Telecommunications
A form of telecommunication which is concerned in any process providing transmission and reproduction at a distance of documentary matter, such as written or printed matter or fixed images, or the reproduction at a distance of any kind of information in such a form. For the purposes of the Radio Regulations, unless otherwise specified therein, telegraphy shall mean a form of telecommunication for the transmission of written matter by the use of a signal code.
