1441 results about "Message format" patented technology

In telecommunication, a message format is a predetermined or prescribed spatial or time-sequential arrangement of the parts of a message that is recorded in or on a data storage medium. At one time, messages prepared for electrical transmission were composed on a printed blank form with spaces for each part of the message and for administrative entries.

Blockchain-based cross-chain interconnection method, device and system

The invention provides a blockchain-based cross-chain interconnection method, a blockchain-based cross-chain interconnection system, computer equipment and a computer readable storage medium, and relates to the technical field of information processing. The system comprises a cross-chain gateway node and a plurality of service chains, each service chain comprises an authority management node, a gateway node and a plurality of verification nodes, and the gateway node in the plurality of service chains and the cross-chain gateway node form a cross-chain gateway; and the cross-chain gateway is used for realizing message format standardization and a cross-chain conversion protocol among the plurality of service chains so as to promote adaptation and forwarding of cross-chain messages, support error processing of request message timeout during cross-chain interconnection and finally realize mutual access and intercommunication of cross-chain data. Mutual access among the alliance chains of a plurality of different block chain technologies is achieved by introducing the bridging gateway chain, the problem of information island among a plurality of block chain systems is solved, and application and popularization of the block chain technology can be accelerated.

Authenticating endpoints of a voice over internet protocol call connection

A method and apparatus for securely establishing voice over Internet Protocol calls are disclosed. In a Registration Security approach, a Gatekeeper sends an Access Token in all Registration Request messages. The Access Token contains information that authenticates the Gateway to the Gatekeeper. The Gatekeeper formats a message to an authentication server that will authenticate the information contained in the token, and the server responds with either an Access-Accept or Access-Reject message. The Gatekeeper responds to the Gateway with either a Registration Confirm message or a Registration Reject message. If a call is then placed from a successfully authenticated Gateway, that Gateway generates a new Access Token that is identical to the one generated during registration, except for the timestamp. The Gatekeeper uses the authentication server to authenticate the originating gateway, before sending the designation side Access Confirm message. As a result, a non-authenticated endpoint that knows a Gateway's address cannot use the Gateway address to circumvent security and access the telephone network to place unauthorized calls or free calls. In Admission or Per-Call Security, a Gateway is also required to include an Access Token in all originating side Admission Request messages. Such token contains information that identifies the user of the Gateway to the Gatekeeper, based on an account number and PIN obtained from the user. The Access Token is authenticated in the manner described above.
