Today, I will talk to you about what is the security mechanism for identity authentication, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can gain something according to this article.

The security mechanisms used to implement identity authentication are encryption mechanism and digital signature mechanism. Encryption is to change the original information data with some special algorithm, so that even if unauthorized users get the encrypted information, they still can not understand the content of the information; signature mechanism all data interfaces must input digital signatures, digital signatures use the "MD5" 32-bit specification.

The security mechanisms used to realize identity authentication are encryption mechanism and digital signature mechanism.

Encryption is to change the original information data with some special algorithm, so that even if unauthorized users get the encrypted information, they are still unable to understand the content of the information because they do not know the method of decryption. In aeronautics, the operation of adding control points to an object or an entire aerial strip by measuring and calculating a small number of control points known on an aerial photograph.

Signature mechanism

All data interface requests must pass in a digital signature, which uses the MD5 32-bit specification.

Signature algorithm calculation rules:

Sign= ((noncestr + openid + PublicKey + timestamp). MD5 () + PrivateKey). MD5 (). ToLower ()

Step one:

/ / concatenate the string String str1 = (random string noncestr + open platform openid + public key PublicKey+ timestamp timestamp); / / A pair of str1 gets str1MD5;String str1MD5 = str1.MD5 () after md5 operation

Step 2:

/ / the second concatenation of the string String str2 = (str1MD5 + private key PrivateKey obtained in the first step); / / A pair of str2 after md5 operation and converted to lowercase 32-bit String sign = str2.MD5 () .ToLower ()

All requests require an incoming digital signature, and the system verifies that the digital signature is correct before making other responses.

Example:

Openid:IOS1101Timestamp:1439950776Noncestr:xy19102724PrivateKey: defe97621eef237896e489228fb68786PublicKey: 38dae8d211692021116dd85793487f6b

Correct sign:6f2573587a4ca0379d32a8975014cc0f

After reading the above, do you have any further understanding of the security mechanism used to implement identity authentication? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
