A Coding Guide to Build an AI-Powered Cryptographic Agent System
This tutorial guides you through the development of an AI-powered cryptographic agent system that integrates classical encryption techniques with adaptive intelligence. The system’s agents are designed to perform hybrid encryption using RSA and AES, generate digital signatures, detect anomalies in communication patterns, and recommend key rotations intelligently. As we progress, these autonomous agents will establish secure communication channels, exchange encrypted messages, and dynamically assess security risks in real-time within an efficient framework.

Setting Up the Environment
We commence by importing essential libraries for cryptography, AI analysis, and data handling. We also define a SecurityEvent dataclass to log important events in the cryptographic system.
Code Snippet: Security Event Definition
@dataclass
class SecurityEvent:
timestamp: float
event_type: str
risk_score: float
details: Dict
Building the CryptoAgent Class
Within this section, we define the CryptoAgent class, initializing its keys, session storage, and security tracking system. The class features methods to generate and exchange RSA public keys and establish securely hybrid-encrypted sessions.
Code Snippet: CryptoAgent Initialization
class CryptoAgent:
def __init__(self, agent_id: str):
self.agent_id = agent_id
self.private_key = rsa.generate_private_key(public_exponent=65537, key_size=2048, backend=default_backend())
self.public_key = self.private_key.public_key()
self.session_keys = {}
self.security_events = []
self.encryption_count = 0
self.key_rotation_threshold = 100
Encrypting and Decrypting Messages
We now implement methods enabling agents to encrypt and decrypt messages securely using AES-GCM. Each communication is encrypted, signed, risk-assessed, and decrypted, ensuring confidentiality and authenticity.
Code Snippet: Encrypt Message Method
def encrypt_message(self, partner_id: str, plaintext: str) -> Dict:
if partner_id not in self.session_keys:
raise ValueError(f"No session established with {partner_id}")
self.encryption_count += 1
if self.encryption_count >= self.key_rotation_threshold:
self.log_security_event("KEY_ROTATION_NEEDED", 0.3, {"count": self.encryption_count})
iv = secrets.token_bytes(12)
cipher = Cipher(algorithms.AES(self.session_keys[partner_id]), modes.GCM(iv), backend=default_backend())
encryptor = cipher.encryptor()
ciphertext = encryptor.update(plaintext.encode()) + encryptor.finalize()
message_data = iv + ciphertext + encryptor.tag
signature = self.sign_data(message_data)
risk_score = self.analyze_encryption_pattern(len(plaintext))
return {
"sender": self.agent_id,
"recipient": partner_id,
"iv": iv.hex(),
"ciphertext": ciphertext.hex(),
"tag": encryptor.tag.hex(),
"signature": signature.hex(),
"timestamp": time.time(),
"risk_score": risk_score
}
AI-Powered Security Analysis
We enhance our agent with AI-driven capabilities that analyze encryption patterns, detect anomalies, and log security events. The agent can identify unusual behavior and generate comprehensive security reports.
Code Snippet: Generate Security Report
def generate_security_report(self) -> Dict:
if not self.security_events:
return {"status": "No events recorded"}
total_events = len(self.security_events)
high_risk_events = [e for e in self.security_events if e.risk_score > 0.7]
avg_risk = np.mean([e.risk_score for e in self.security_events])
event_types = {}
for event in self.security_events:
event_types[event.event_type] = event_types.get(event.event_type, 0) + 1
return {
"agent_id": self.agent_id,
"total_events": total_events,
"high_risk_events": len(high_risk_events),
"average_risk_score": round(avg_risk, 3),
"encryption_count": self.encryption_count,
"key_rotation_needed": self.encryption_count >= self.key_rotation_threshold,
"event_breakdown": event_types,
"security_status": "CRITICAL" if avg_risk > 0.7 else "WARNING" if avg_risk > 0.4 else "NORMAL"
}
Demo of the Crypto Agent System
Finally, we present a demonstration of the complete workflow where two agents securely exchange messages, assess security, and generate comprehensive reports. This demo highlights the integration of AI with traditional cryptographic techniques.

print("=" * 60)
alice = CryptoAgent("Alice")
bob = CryptoAgent("Bob")
print("\n1. Agents Created")
print(f" Alice ID: {alice.agent_id}")
print(f" Bob ID: {bob.agent_id}")
