In the process of Elliptic curve operation, the results of 256-bit addition and subtraction are often outside the interval [0,p], and the operation of +p or-p is required. The 256-bit NIST domain Elliptic curve parameter p is generated in the following formula: p = 2^256?2^224 + 2^192 + 2^96? 1 The formula is broken down by the symbol: p = (2^256 + 2^192 + 2^96)-(2^224 + 1) Convert to 16 and press the 64-bit section to change to the following form: +:

This is the generation formula for the 256-bit NIST prime-domain elliptic curve primes p:p256 = (2 ^ 256)?(2 ^ 224) + (2 ^ 192) + (2 ^ 96)? 1The 64-bit section breaks it down into an addition vector as follows:1 0000000000000001 0000000000000000 0000000100000000 0000000000000000-0000000100000000 0000000000000000 0000000000000000 0000000000000001= ffffffff00000001 0000000000000000 00000000ffffffff ffffffffffffffffHaving a positive integer n, whose valu

the flexibility of the Protocol and the simplicity of processing.The RTP protocol and UDP both complete the Transport Layer protocol function. The UDP protocol simply transmits packets regardless of the time sequence in which the packets are transmitted. RTP protocol data units are hosted with UDP packets. When hosting RTP packets, sometimes a frame of data is divided into several packages with the same time label, you can know that the time tag is not necessary. UDP multiplexing enables the RT

function. UDP only transmits data packets regardless of the time sequence of data packets. RTP protocol data units are carried by UDP groups. When carrying RTP data packets, sometimes a frame of data is divided into several packets with the same time tag, you can know that the time tag is not necessary. The multiplexing of UDP allows the RTP protocol to meet the needs of multimedia sessions by supporting explicit multi-point delivery.Although the RTP protocol is a transport layer protocol, it i

number is also used to determine the correct location of a packet, for example, without sequentially decoding the packet when the video is decoded. But RTP's original design was designed to meet the needs of multi-participant multimedia conferencing, which was not limited to specialized applications. Storage of continuous data, interactive distributed simulations, dynamic tagging, and control and measurement applications may also be suitable for use with RTP. 1, RTP fixed head structure RTP fix

works in the same way as the HTTP1.1, the caching of proxy server "cache" also applies to RTSP, and because RTSP has a re-directed function, the actual load situation can be converted to serve the server, To avoid excessive load concentration on the same server and cause delays. RTSP's request mainly has describe,setup,play,pause,teardown,options and so on, as the name implies can know the dialogue and control role. During the RTSP conversation, Setup can determine the port used
