Which is the secure way to communicate between client and server?

SSL is a security protocol that secures communication between entities (typically, clients and servers) over a network. SSL works by authenticating clients and servers using digital certificates and by encrypting/decrypting communication using unique keys that are associated with authenticated clients and servers.

How do you secure Intent process communication when developing your application?

Security tips

1. On this page.
2. Store data. Use internal storage. Use external storage. Use content providers.
3. Use permissions. Request permissions. Create permissions.
4. Use networking. Use IP networking. Use telephony networking.
5. Perform input validation.
6. Handle user data.
7. Use WebView. Handle credentials.
8. Use cryptography.

Can a server certificate be used as a client certificate?

Cryptographically, you can use either as the actual client side identity of an SSL connection, but the other side (the server on that particular connection) has to accept the certificate; most people don’t put the Distinguished Name of servers into the database of acceptable identities.

What is server certificate and client certificate?

Server certificates are used to authenticate server identity to the client(s). Client certificates are used to authenticate the client (user) identity to the server. No encryption of data takes place in case of Client certificates. Server Certificates are based on PKI. Client certificates are based on PKI.

Which of the following makes a secure connection between a client and a server?

Secure Socket Layer (SSL) SSL is the standard security technology for establishing an encrypted link between the two systems. These can be browser to server, server to server or client to server. Basically, SSL ensures that the data transfer between the two systems remains encrypted and private.

Which of the following makes a secure connection between a client and a server HTTP or HTTPS?

HTTP lacks security mechanism to encrypt the data whereas HTTPS provides SSL or TLS Digital Certificate to secure the communication between server and client. HTTP by default operates on port 80 whereas HTTPS by default operates on port 443.

How do you implement client certificate authentication?

1. Purchase and Generate a Client Authentication Certificate.
2. Complete the Validation Process.
3. Download or Export the User’s Client Certificate.
4. Import the Client Authentication Certificate to Your OS & Browser Certificate Stores.
5. Configure Your Server to Support Client Authentication.
6. Test Your Certificate to Ensure It Works.

How do certificates work in authentication?

Certificate-based authentication is based on what the user has, which is the user’s private key, and what the user knows, which is the password that protects the private key (if the key is not located in a secure keystore).

How is HTTPS secured?

How does HTTPS work? HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL). This protocol secures communications by using what’s known as an asymmetric public key infrastructure.

How would you establish SSL connection between client and server?

How an SSL connection is established

1. The client sends a request to the server for a secure session.
2. The client receives the server’s X.
3. The client authenticates the server, using a list of known certificate authorities.
4. The client generates a random symmetric key and encrypts it using server’s public key.

How do I authenticate the server with a certificate?

For both the client and the server programs, you should use the certificates file samplecacerts from the samples directory. Using this certificates file will allow the client to authenticate the server.

How to authenticate a user in an encrypted communication?

The first encrypted communication will be used to authenticate the user – i.e. checking his/her user name and password. After the user credentials will be successfully checked by server I would like to start getting some data in subsequent requests.

Why do I need a certificate for the sample server?

Using this certificates file will allow the client to authenticate the server. The file contains all the common Certificate Authority (CA) certificates shipped with the JDK (in the cacerts file), plus a certificate for localhost needed by the client to authenticate localhost when communicating with the sample server ClassFileServer.

Which type of authentication takes the highest precedence over HTTP authentication?

NOTE: As the SSL Handshake happens before HTTP communication, Client Certificate Authentication takes the highest precedence over any other type of authentication that takes place over HTTP protocol. Kerberos, Client Certificate Authentication and Smart Card Authentication are examples for mutual authentication mechanisms.
