Problems solved by technology

[0002] At present, smart terminal devices such as smartphones are widely popularized. When users use these smart terminal devices to communicate, the communication content is easily monitored and stolen by malicious software.
However, the existing encrypted communication methods usually use software encryption algorithm or hardware encryption algorithm, and the key information is directly included in the interactive message during the process of establishing a call between the calling party and the called party. This method is easy to cause the key information to be Stealing, making the call process of both parties vulnerable to Man-in-the-Middle Attack (MITM), resulting in encrypted call content being cracked, tampered with and sniffed, bringing security risks to users

Embodiment 1

[0037] see figure 1 , figure 1 It is a schematic flow chart of an identity authentication method provided in Embodiment 1 of the present invention. The execution subject of this embodiment includes a terminal and a server, where the terminal may be a smart phone or other smart terminal. figure 1 The shown identity authentication method may include the following steps:

[0038] S101. The terminal randomly generates a signature key pair including a signature public key and a signature private key.

[0039] Specifically, the signature key pair randomly generated by the terminal is used for performing a digital signature and verifying the digital signature.

[0040] S102. The terminal uses the signature public key to apply for a digital certificate and an encryption key pair from the server, where the encryption key pair includes an encryption public key and an encryption private key.

[0041] Specifically, the server includes a certificate authority (Certificate Authority, CA)...

Embodiment 2

[0058] see figure 2 , figure 2 It is a schematic flow chart of an identity authentication method provided in Embodiment 2 of the present invention. The execution subject of this embodiment includes a terminal and a server, wherein the terminal may be a smart phone or other smart terminal. figure 2 The shown identity authentication method may include the following steps:

[0059] S201. The terminal randomly generates a signature key pair including a signature public key and a signature private key.

[0060] Specifically, the signature key pair randomly generated by the terminal is used for performing a digital signature and verifying the digital signature.

[0061] S202. The terminal sends a digital certificate application request including the signature public key to the server.

[0062] Specifically, the server includes a CA function, which can implement functions such as issuing certificates, authenticating certificates, and managing issued certificates. The terminal ...

Embodiment 3

[0102] see Figure 4 , Figure 4 It is a schematic block diagram of an identity authentication system provided by Embodiment 3 of the present invention. For ease of description, only parts related to the embodiments of the present invention are shown. Figure 4 The example identity authentication system 300 may be the execution subject of the identity authentication method provided in the first embodiment. Figure 4 The example identity authentication system 300 mainly includes a terminal 31 and a server 32, and the details are as follows:

[0103] Terminal 31 includes:

[0104] A key generating unit 311, configured to randomly generate a signature key pair comprising a signature public key and a signature private key;

[0105] A certificate application unit 312, configured to use the signature public key generated by the key generation unit 311 to apply to the server for a digital certificate and an encryption key pair, wherein the encryption key pair includes an encrypti...

Abstract

The embodiment of the invention discloses an identity authentication method and system, and the method comprises the steps that a terminal randomly generates a signature secret key pair comprising a signature public key and a signature secret key; the terminal uses the signature public key to apply for a digital certificate and an encryption secret key pair from a server; the terminal carries out the signature of a first interaction message in a process of building communication with opposite terminal equipment through the signature secret key, and enables the first interaction message after signature to be transmitted to the opposite terminal equipment; the terminal carries out the signature of the digital certificate of the terminal equipment through the server if the terminal receives a second interaction message sent by the opposite terminal equipment; and the terminal confirms the valid identity of the opposite terminal equipment if the signature verification is passed. According to the embodiment of the invention, the method can carry out the verification of the validity of the identities of two communication sides of intelligent terminals through the valid generation and transmission of the digital certificate and the combination with the server to complete the signature and signature verification processes, and guarantees the safe transmission of communication contents.
