However, some transmission channels cannot support channel encryption such as Transport Layer Security (TLS), or the client and the server agree on a fixed transmission key (the key used to encrypt the transmitted key) to protect the transmitted secret. key (the key itself that needs to be transmitted), and the security of this fixed transmission key itself has been questioned

Abstract

The invention discloses a dynamic secret key protection method and system. The method comprises the following steps: generating a character string with a first length according to one or more custom variables; performing logical operation on the character string and a static character string to generate a dynamic character string with the first length, wherein the static character string is configured to be a second length and comprises a first section and a second section; performing left shift operation of one or more bits on the first section, performing right shift operation of one or more bits on the second section, and performing merging to generate a static character string after shift operation; and combining the dynamic character string with the static character string after the shift operation to generate a transmission key with a third length.

Description

technical field [0001] This specification generally relates to the technical field of data encryption, and specifically relates to a method and system for dynamic key protection. Background technique [0002] With the rapid development of the Internet, information security issues have attracted more and more attention, and information security technology based on data encryption technology has also developed rapidly. In the process of data transmission, especially when more sensitive key information needs to be transmitted, special processing of the key information is required to improve the security of the transmission. However, some transmission channels cannot support channel encryption such as Transport Layer Security (TLS), or the client and the server agree on a fixed transmission key (the key used to encrypt the transmitted key) to protect the transmitted secret. key (the key itself that needs to be transmitted), and the security of this fixed transmission key itself...
