What is the value of upgrading HTTPS?
HTTPS is essentially a protocol for secure information communication. From the perspective of final data parsing, there is no fundamental difference between HTTPS and HTTP. For the receiver, SSL/TSL decrypts the received data packets and transmits the data to the HTTP protocol layer, which forms the HTTP data. HTTPS encrypts HTTP packets through the SSL/TSL layer to ensure the security of the transmitted data.
SSL/TSL is a layered protocol, which consists of two layers, in which SSL/TSL handshake protocol allows the server and the client to authenticate each other and negotiate an encryption algorithm and session key before the data is transmitted by the application layer protocol. The handshake protocol of SSL/TSL mainly exchanges digital certificate, random number and secret communication protocol to ensure the security of access.
L data confidentiality. To ensure that the content will not be seen by a third party in the process of transmission, it is realized through asymmetric encryption and key exchange.
L data integrity. The transmission content tampered by a third party can be found in time to ensure that the integrity of the data is maintained in a timely manner.
L identity verification. Ensure that the data reaches the desired destination, that is, PKI and digital certificate.
How can enterprises change from http to https more conveniently and quickly?
The best solution: it is very simple to contact Yi Wei Xin to purchase SSL certificate as soon as possible, deploy https protocol for APP, and make server upgrade to use TLS1.2. This is the single fastest, most convenient and effective solution. Apple has stepped up the control of application security this time, which shows that Apple attaches great importance to information security, and it also reveals that most applications transmit data without encryption, so it is right to use HTTPS to ensure information security as soon as possible. It also saves the security risks of private encryption protocols!
