Cryptoanalysis Significance in IT Security

Almost all of us in the present time communicate and exchanges data over the internet without giving importance to security. We all leave behind digital footprints across the internet world even when sharing private information. This calls for the requirement for cryptocurrency so private information can be protected and no intruder can get access to it. So, what cryptoanalysis are?

In simple words, cryptoanalysis provides digital codes and keys to help make certain that information is sent from a trustworthy sender and receiver gets the exact information without being interfered with. Here in this post, we will learn all about cryptanalysis, from its working to its practical application.

What is cryptoanalysis?

Cryptoanalysis is the process of hiding all crucial and sensitive information through codes and keys. This practice takes the help of complex mathematical calculations and multiple rules named algorithms to make the information uneasy to decipher.

Cryptoanalysis includes two processes that are encryption and decryption.

Encryption is the data conversion that is sent by the sender in an incomprehensible format. The encrypted data is composed of codes so that the third person doesn’t have access to it and fails to understand it.

Decryption is the data conversion of the encrypted text to the original one sent by the sender to make it easy to read by the receiver.

When data is decrypted or encrypted, it is vital to know about the algorithms that you should use. For example, SHA, RCA, and MDS are weak ciphers. They all can be used for decrypting and encrypting less sensitive information. The sensitive data such as credit card details, using an algorithm such as AES 256 is suggested.

What problems are solved by cryptoanalysis?

Two kinds of attacks are there orchestrated in the open networks

1- Passive attacks

The attacker listens to the network connection and reads the information as it is sent.

2- Active attacks

The attacker impersonates a server or client and intercepts the message in transit and modifies the information and then redirects it to the receiver or server.

Cryptoanalysis safeguards such kinds of attacks with the help of its 4 pillars of security.

1- Integrity

2- Confidentiality

3- Non-repudiation

4- Authenticity

Cryptoanalysis protocols namely TLS and SSL provide confidentiality and integrity by safeguarding communications against malicious ones. Authentication protection is given by encryption wherein the message is encrypted along with a private key and sent to the receiver.
