**What is meant by modern cryptography? **

The efficiency of modern cryptography is majorly based on cryptographic keys. It uses short text strings for *data encryption and data decryption processes using cryptographic techniques*. These techniques may vary utilizing key types.

As you know well, there are 2 types of cryptographic keys as **asymmetric key cryptography and symmetric key cryptography**. Here, both these types of keys ensure data privacy. As well, the other name of asymmetric key cryptography is public-key cryptography.

**What are modern cryptography objectives?**

On using mathematical concepts, cryptography enables you to securely encode and decode data inefficient way. Consequently, it ensures data protection in both storage and transmission. So, unauthorized third parties are not allowed to **access data without verifying the encryption key.** Building unbreakable encryption techniques make the cryptosystem stronger than others.

Now, we can see the **list of major cryptographic attacks in recent developments**. In general, the main aim of attackers is to acquire the information of the cryptosystem for performing malicious activities.

Mainly, the attacker attempts to break encrypted data for **identifying hidden original information.** In other words, attackers look for the plain text from the ciphertext. For that, the attacker needs to find a decryption key. There are available techniques available in several public domains to track the encryption.

So, the attackers are ready to spend more time and energy to detect the secret key which is required for the decryption process of cryptography projects with source code. If the attackers correctly compute the key, then it is easy for them to **compromise the whole network/system**. For your knowledge, we have given you some basic and advanced cryptographic attacks over cryptosystems.

**List of Cryptographic Attacks**

**Man-in-the-Middle Attack**- Here, the attacker tries to get key information before data sharing
- Majorly, it is performed in public-key cryptosystems
- For instance:
- Host X demands the public key of Host Y for communication establishment
- At that time, the attacker interrupts and send its public key
- So, an attacker can easily get the information to send by Host X
- Once the attacker reads the information, then again re-encrypts the information and transmit it to Host Y
- Particularly, the attacker transmits its own public key instead of Host X’s public key
- So, both Host X and Host Y are unaware of information revelation

**Timing Attack**- Here, the attacker gets useful information about the encryption key by analyzing computation time
- Generally, time varies from one computation to another while execution
- So, it measures the computation time taken by the processor
- For instance: When the encryption process takes more time, the secret key length is long

**Known Plaintext Attack**- Here, the attacker will get a few parts of plain text information
- Able to decrypt an only remaining portion of ciphertext
- Use some decryption techniques or compute the decryption key
- For instance: linear cryptanalysis on block ciphers

**Power Analysis Attack**- Here, the attacker gets the information about computation nature and power utilization
- As well, it is similar to timing attacks

**Dictionary Attack**- Here, the attacker will prepare a dictionary based on experience
- Actually, dictionary holds ciphertext with respective plain text
- Since this attack comprises different variants based on ‘dictionary’
- Henceforth, an attacker can match ciphertext with dictionary to identify plain text

**Fault Analysis Attack**- Here, the attacker induces errors to cryptosystem
- Then, the attacker examine resultant for acquiring useful information

**Ciphertext Only Attack**- Here, the attacker will get ciphertext information but not plain text
- Through ciphertext, attacker can determine the encryption key in some cases
- Otherwise, an attacker can compute plain text from the obtained ciphertext

**Birthday Attack**- Here, the attacker performs computation against hashing method
- As well, it is different from a brute-force attack
- For instance:
- Assume you have an input that the first person birth date is 21st April and You have to find the second person birthdate which is also the same 21st April. Then, the answer is from any of 365 days.
- To acquire second person birthdate, it requires to investigate 1.25*√365 ≈ 25 persons

- Likewise, the hash function generates 64bit hash values which result in 1.8×1019 probable hash values
- Repeat investigation by different input until you get the same output after 5.1×109 random inputs
- When the attacker can identify dissimilar inputs for the same hash values, the hash function is cracked down

**Brute Force Attack**- Here, the attacker uses all applicable keys to compute the actual key
- For instance: an 8bit key has 256 probabilities where the attacker tries all keys for decryption
- If the key size is high then it takes more time to find the actual key

**Chosen Plaintext Attack**- Here, the attacker will get choice-based plain text and find respective ciphertext
- Therefore, the attacker acquires ciphertext-plaintext pair based on their interest
- So, it is easy to find an encryption key to get whole plain text
- For instance: Hah function and differential cryptanalysis on block ciphers
- Further, Public key cryptosystem – RSA susceptible to chosen-plaintext attacks

**Side-Channel Attack**- Here, the attacker launches this attack to create multiple vulnerabilities in a physical cryptosystem
