### Super RSA Versatile Key (SRVK) Algorithm

The "Super RSA Versatile Key" (SRVK) is an advanced cryptographic algorithm inspired by RSA that introduces additional layers of security and flexibility. It is designed to work with both traditional RSA encryption and decryption paradigms while addressing some common vulnerabilities and limitations of RSA through enhanced key versatility and hybrid encryption techniques.

### Key Features of SRVK

1. **Dual Key Structure**: SRVK uses two types of keys for encryption and decryption:
   - **Primary RSA Key Pair**: This consists of a traditional RSA public and private key pair.
   - **Secondary Symmetric Key Pair**: This introduces an auxiliary symmetric key for hybrid encryption and added security.
   
2. **Variable Key Sizes**: SRVK supports versatile key sizes to allow flexibility between performance and security. RSA key sizes range from 2048 bits to 8192 bits, while the secondary symmetric key can be dynamically adjusted between 128 bits and 256 bits.

3. **Hybrid Encryption**: SRVK combines asymmetric RSA encryption with symmetric encryption. The symmetric key is encrypted with the RSA public key, further used to encrypt the actual data. This allows SRVK to handle large data more efficiently while maintaining RSA’s strong encryption for the key exchange.

4. **Key Rotation Mechanism**: SRVK introduces an optional key rotation scheme, where the symmetric key can be periodically or conditionally rotated to prevent long-term exposure of the same key material.

5. **Multiple Data Blocks**: SRVK supports encryption of large datasets by splitting them into blocks and encrypting each block with a different symmetric key, which is then encrypted using the RSA public key.

### SRVK Algorithm Overview

#### 1. **Key Generation**

SRVK generates two types of keys:
- **RSA Primary Key Pair**: A standard RSA key pair (public and private keys) is generated.
- **Symmetric Key**: A symmetric key (AES-128 or AES-256) is generated for the actual encryption of the data.

#### 2. **Encryption Process**

Let’s break down the encryption process into its components:

**Inputs:**
- The plaintext message \( M \)
- Primary RSA public key \( (e, N) \)
- Symmetric key \( K_{\text{sym}} \)

**Steps:**
1. **Split Data**: If the data \( M \) exceeds a predefined block size threshold, split \( M \) into \( M_1, M_2, ..., M_n \) where \( M_i \) are the blocks.
2. **Encrypt Data with Symmetric Key**: Encrypt each block \( M_i \) using a symmetric encryption algorithm such as AES with the symmetric key \( K_{\text{sym}} \):
   \[
   C_i = \text{AES-Encrypt}(M_i, K_{\text{sym}})
   \]
3. **Encrypt Symmetric Key with RSA**: Encrypt the symmetric key \( K_{\text{sym}} \) using the RSA public key \( (e, N) \):
   \[
   C_{\text{key}} = K_{\text{sym}}^e \mod N
   \]
4. **Concatenate Ciphertext**: The final ciphertext \( C \) is the concatenation of the encrypted symmetric key \( C_{\text{key}} \) and the encrypted blocks \( C_1, C_2, ..., C_n \):
   \[
   C = C_{\text{key}} || C_1 || C_2 || ... || C_n
   \]

#### 3. **Decryption Process**

The decryption process involves reversing the encryption steps:

**Inputs:**
- Ciphertext \( C \)
- Primary RSA private key \( (d, N) \)

**Steps:**
1. **Extract Components**: Extract the encrypted symmetric key \( C_{\text{key}} \) and the encrypted blocks \( C_1, C_2, ..., C_n \) from the ciphertext.
2. **Decrypt Symmetric Key**: Decrypt the symmetric key \( K_{\text{sym}} \) using the RSA private key \( (d, N) \):
   \[
   K_{\text{sym}} = C_{\text{key}}^d \mod N
   \]
3. **Decrypt Data**: Decrypt each ciphertext block \( C_i \) using the symmetric key \( K_{\text{sym}} \):
   \[
   M_i = \text{AES-Decrypt}(C_i, K_{\text{sym}})
   \]
4. **Reassemble Data**: Reassemble the original message \( M \) by concatenating all the decrypted blocks \( M_1, M_2, ..., M_n \).

#### 4. **Key Rotation**

To enhance security, SRVK includes a key rotation mechanism:
- After a certain amount of data has been encrypted or after a predetermined time period, the symmetric key \( K_{\text{sym}} \) can be rotated.
- The new symmetric key is then encrypted using the RSA public key and sent to the recipient, who can decrypt it with the private key.

### Example Pseudocode for SRVK

```python
# Pseudocode for SRVK Key Generation, Encryption, and Decryption

import rsa
from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes

# 1. Key Generation
def generate_keys(key_size=2048):
    # Generate RSA keys
    rsa_pub_key, rsa_priv_key = rsa.newkeys(key_size)
    # Generate a symmetric key (AES key)
    symmetric_key = get_random_bytes(32)  # 256-bit AES key
    return rsa_pub_key, rsa_priv_key, symmetric_key

# 2. Encryption
def srvk_encrypt(message, rsa_pub_key, symmetric_key):
    # Encrypt the message with AES
    aes_cipher = AES.new(symmetric_key, AES.MODE_GCM)
    ciphertext, tag = aes_cipher.encrypt_and_digest(message)
    
    # Encrypt the symmetric key with RSA
    enc_symmetric_key = rsa.encrypt(symmetric_key, rsa_pub_key)
    
    # Return both encrypted symmetric key and AES ciphertext
    return enc_symmetric_key, ciphertext, aes_cipher.nonce, tag

# 3. Decryption
def srvk_decrypt(enc_symmetric_key, ciphertext, nonce, tag, rsa_priv_key):
    # Decrypt the symmetric key with RSA
    symmetric_key = rsa.decrypt(enc_symmetric_key, rsa_priv_key)
    
    # Decrypt the message with AES
    aes_cipher = AES.new(symmetric_key, AES.MODE_GCM, nonce=nonce)
    message = aes_cipher.decrypt_and_verify(ciphertext, tag)
    
    return message
```

### Security Considerations

1. **RSA Security**: The security of SRVK relies on the strength of RSA encryption, which is secure under the assumption that factoring large prime numbers is computationally infeasible.
2. **Symmetric Key Security**: The security of the symmetric key is protected by RSA encryption. The symmetric key itself (AES-128 or AES-256) provides strong encryption for the data.
3. **Padding and Integrity**: RSA encryption should use OAEP padding to prevent chosen ciphertext attacks. AES in GCM mode ensures data integrity and provides authenticity via the **tag**.

### Advantages of SRVK

- **Efficiency**: By using symmetric encryption for large data blocks, SRVK reduces the performance overhead of RSA encryption.
- **Versatility**: SRVK is flexible in terms of key sizes and supports hybrid encryption, making it suitable for a wide range of applications.
- **Security**: Combining RSA with symmetric encryption and key rotation adds layers of security, making it resistant to various cryptographic attacks.

### Conclusion

The "Super RSA Versatile Key" (SRVK) algorithm enhances traditional RSA by incorporating symmetric encryption and key rotation, offering a more secure and efficient cryptographic system. It's suitable for scenarios requiring both high security and flexibility in handling large datasets.
