How the confidentiality and integrity is achieved in SSL communication?

How SSL and TLS provide confidentiality. SSL and TLS use a combination of symmetric and asymmetric encryption to ensure message privacy. During the SSL or TLS handshake, the SSL or TLS client and server agree an encryption algorithm and a shared secret key to be used for one session only.

How does encryption and decryption work in SSL?

How SSL Uses both Asymmetric and Symmetric Encryption

1. Server sends a copy of its asymmetric public key.
2. Browser creates a symmetric session key and encrypts it with the server’s asymmetric public key.
3. Server decrypts the encrypted session key using its asymmetric private key to get the symmetric session key.

Does TLS guarantee integrity?

How TLS provides integrity. TLS provides data integrity by calculating a message digest. For more information, refer to Data integrity of messages. Use of TLS does ensure data integrity, provided that the CipherSpec in your channel definition uses a hash algorithm as described in the table in Enabling CipherSpecs.

When do you decrypt traffic over SSL / TLS?

You can only decrypt traffic for the services that you provide and control on your network. When a client initiates a connection to a server over SSL/TLS, a series of handshake exchanges identify the cipher suite that includes the set of algorithms that encrypts the data and authenticates the data integrity.

When to use TLS to ensure message integrity and confidentiality?

In particular, the client needs to verify the certificate to ensure it is communicating with the right server (verifying that the certificate is genuine and issued by a trusted party, and issued to the host name it intended to contact). Use TLS to ensure message confidentiality over the wire.

Can a message analyzer decrypt TLS v1.2 messages?

Please be aware that decryption of TLS v1.2 messages is also supported, as is TDS/TLS. The Message Analyzer Decryption feature enables you to view data for Application layer protocols that are encrypted with TLS and SSL, such as the HTTP and Remote Desktop (RDP) protocols.

Which is the transparent proxy for SSL decryption?

SSL proxy is a transparent proxy that performs SSL encryption and decryption between the client and the server. SRX acts as the server from the client’s perspective and it acts as the client from the server’s perspective.
