Problems solved by technology

In the prior art, the data is usually directly transmitted after TLV encoding. Since the TLV encoding is relatively simple, it can be easily deciphered. Therefore, the transmission of TLV data using the prior art has the following defects: once the transmitted data is captured by other users , experienced hackers or developers can easily identify the TLV format, which can cause information leakage and even threaten the security of the entire system

Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

[0050] see figure 1 , which is a flowchart of the first embodiment of a TLV-based data transmission method provided by the present invention. To illustrate the embodiment of the present invention more clearly, in the transmission process, the two transmission parties are respectively referred to as the first transmission party and the second transmission party.

[0051] Step 110: the first transmission party acquires the first public key in the pre-generated first...

Abstract

The invention discloses a TLV (Threshold Limit Value) based data transmission method comprising the following steps of: encoding original data to be transmitted through a TLV encoding manner to generate TLV data; encrypting the TLV data to generate encrypted TLV data; and transmitting the encrypted TLV data. The invention further discloses a TLV-based data transmission system. Through a technical scheme in the invention, the transmission safety of the TLV data can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a TLV-based data transmission method and system. Background technique [0002] TLV (Tag tag, Length length, Value value) is a data encoding format, in which the tag (Tag) field is information about the tag and encoding format, the length (Length) field defines the length of the value, and the content (Value) field indicates actual value. Therefore, an encoded value is also called a TLV (Tag, Length, Value) triplet. An encoding can be primitive or structured. An encoding is primitive if it represents a complete explicit value of a simple type, or constructed if the value it represents has a nested structure. . [0003] At present, TLV encoding is mainly used to transmit structured data in streaming media. A typical application is to transmit structured data in the network. TLV encoding converts object data into binary streams for transmission in the network. In the prior art...
