Secured authentication 3d password

There are perfectly legitimate scenarios that require that feature; unfortunately there are also many ways in which abusing this feature might backfire. When to Use This Feature There are a number of scenarios where the direct use of username and password is inevitable. The ones below are the ones I encountered most often.

The differences between SSL 3. However, these updated versions are not as widely supported as TLS 1. Transferring sensitive information over a network can be risky due to the following issues: You cannot always be sure that the entity with whom you are communicating is really who you think it is.

Network data can be intercepted, so it is possible that it can be read by an unauthorized third party, sometimes known as an attacker.

An attacker who intercepts data may be able to modify it before sending it on to the receiver. SSL addresses each of these issues. It addresses the first issue by optionally allowing each of two communicating parties to ensure the identity of the other party in a process called authentication.

Once the parties are authenticated, SSL provides an encrypted connection between the two parties for secure message transmission.

Encrypting the communication between the two parties provides privacy and therefore addresses the second issue. The encryption algorithms used with SSL include a secure hash function, which is similar to a checksum.

This ensures that data is not modified in transit. The secure hash function addresses the third issue of data integrity. Both authentication and encryption are optional, and depend on the the negotiated cipher suites between the two entities.

An e-commerce transaction is an obvious example of when to use SSL. In an e-commerce transaction, it would be foolish to assume that you can guarantee the identity of the server with whom you are communicating. It would be easy enough for someone to create a phony web site promising great services if only you enter your credit card number.

SSL allows you, the client, to authenticate the identity of the server. It also allows the server to authenticate the identity of the client, although in Internet transactions, this is seldom done. Once the client and the server are comfortable with each other's identity, SSL provides privacy and data integrity through the encryption algorithms that it uses.

This allows sensitive information, such as credit card numbers, to be transmitted securely over the Internet. Although SSL provides authentication, privacy, and data integrity, it does not provide nonrepudiation services. Nonrepudiation means that an entity that sends a message cannot later deny sending it.

When the digital equivalent of a signature is associated with a message, the communication can later be proved. SSL alone does not provide nonrepudiation. SSL uses public-key cryptography to provide authentication, and secret-key cryptography with digital signatures to provide for privacy and data integrity.

Before you can understand SSL, it is helpful to understand these cryptographic processes.

For the best of these currently in use, it is not known whether there can be a cryptanalytic procedure that can reverse or, usefully, partially reverse these transformations without knowing the key used during encryption.

Cryptographic Processes The primary purpose of cryptography is to make it difficult for an unauthorized third party to access and understand private communication between two parties. It is not always possible to restrict all unauthorized access to data, but private data can be made unintelligible to unauthorized parties through the process of encryption.

Encryption uses complex algorithms to convert the original message cleartext to an encoded message ciphertext. The algorithms used to encrypt and decrypt data that is transferred over a network typically come in two categories: These forms of cryptography are explained in the following subsections.

Both secret-key cryptography and public-key cryptography depend on the use of an agreed-upon cryptographic key or pair of keys. A key is a string of bits that is used by the cryptographic algorithm or algorithms during the process of encrypting and decrypting the data.

A cryptographic key is like a key for a lock; only with the right key can you open the lock. Safely transmitting a key between two communicating parties is not a trivial matter. A public key certificate enables a party to safely transmit its public key, while ensuring the receiver of the authenticity of the public key.

Public key certificates are described in a later section. The descriptions of the cryptographic processes that follow use conventions widely used by the security community: The unauthorized third party, also known as the attacker, is named Charlie.
