Advanced Encryption at the Heart of Atomic Mail
Atomic Mail is redefining the concept of secure email communication. Our approach is underpinned by a security-first principle, embedded within the platform's architecture. Unlike many other providers who offer email encryption as an advanced feature, we’ve created a system where every interaction is protected by default. This is not merely an afterthought, but rather a fundamental principle that shapes our entire business model.
What truly sets us apart, however, is our approach to client-side encryption processes alongside a zero-knowledge infrastructure. This means your data is encrypted on your device before it ever touches our servers, so even we cannot access it. The keys remain solely in your hands. No middlemen, no vulnerabilities – just absolute control over your privacy.
Why Advanced Encryption is Central to Our Security Model
Many services advertise "encryption" often limited to transport layer security. That is akin to securing the front entrance while leaving all other access points open. We have gone beyond, implementing true end-to-end email encryption.
As experts have long emphasized, true security begins with user-controlled keys and comprehensive data protection. At Atomic Mail, we have integrated this principle into the core of our system. End-to-end encryption is not an optional feature; it is a fundamental element for safeguarding privacy. It is the only way to ensure your communications remain secure. Would you consider a system that does not offer this fundamental protection?
Transport-Level Encryption. How We Secure Your Data in Transit
What is Transport-Level Encryption and Why Does It Matter?
When you send an email, it doesn’t go directly from your device to the recipient’s inbox. Instead, it passes through multiple servers and networks, each creating a potential risk of interception. Transport-level encryption acts as a secure tunnel, shielding your data as it moves across the internet. Without it, your emails would be like postcards – visible to anyone who handles them along the way. However, not all implementations of transport-layer security are equal. Many outdated email services still rely on older protocols that leave users vulnerable.
Atomic Mail’s Use of TLS 1.3: The Industry’s Strongest Transport Security
Atomic Mail uses TLS 1.3, the latest and most advanced version of the Transport Layer Security protocol. Unlike older versions, TLS 1.3 is designed to be faster, more efficient, and significantly more secure.
Key aspects of our implementation:
- Forced TLS 1.3 connections for all client-server communication.
- Implementation of strong cipher suites.
- Regular security audits to ensure compliance and effectiveness.
We use TLS 1.3 by default, because it is the best currently available protocol for encryption during transit.
End-to-End Encryption Using Our Unique Protocol
At Atomic Mail, we’ve developed a new and advanced end-to-end email encryption solution that represents a significant step beyond conventional methods. We've engineered our unique Atomic Encryption protocol, a sophisticated blend of advanced cryptographic techniques. This isn't merely an adaptation of existing standards.
It's a bespoke solution, designed to provide the highest level of security. We employ a hybrid cryptographic system, leveraging the strengths of both symmetric and asymmetric encryption for optimal safety and efficiency.
Atomic Encryption Technology:
- Proprietary protocol combining AES-256, AES-256-CBC, and ECIES.
- Automatic key management, eliminating user complexity.
- "Blockchain-level" security leveraging advanced cryptographic standards.
How We Ensure Only the Sender & Recipient Can Read Emails
Our system ensures that only the intended recipient can decipher your messages. This is achieved through a multi-layered encryption process, designed to be both robust and seamless.
AES-256 (Symmetric Encryption)
- Purpose: Encrypts the email content itself.
- Why AES-256?
- Speed: Exceptionally fast, crucial for encrypting large data volumes.
- Security: Considered one of the most secure encryption algorithms, resistant to brute-force attacks.
- AES-256-CBC adds a layer of chaining to the encryption, making it even harder to crack than basic AES.
- How It Works:
- A random AES key is generated locally on the sender's device.
- This key encrypts the entire email content, making it unreadable to anyone without decryption access.
ECIES (Asymmetric Encryption)
- Purpose: Encrypts the AES-256 secret key for each recipient.
- Why ECIES?
- Secure Key Transmission: Allows safe distribution of the AES-256 key without prior key exchange.
- Personalized Encryption: Each recipient receives a unique, encrypted key.
- How It Works:
- Each recipient has a unique public key based on the Ethereum (0x...) standard.
- The AES-256 secret key is encrypted using the recipient’s public key with ECIES.
- This ensures that each recipient receives a uniquely encrypted email key that only they can unlock with their private key.
The Hybrid System Advantage
- AES-256 ensures fast and efficient content encryption.
- ECIES provides secure key distribution and personalized protection.
Sending E2EE Emails to Atomic Users
Let's illustrate how our end-to-end email encryption functions within the Atomic Mail ecosystem, using Alice sending an email to Bob (both Atomic Mail users) as an example:
- Compose: Alice drafts her email and chooses Bob (another Atomic Mail user) as the recipient. She selects "Atomic Encryption" for seamless E2EE.
- Local Encryption with AES-256: On Alice's device, a unique secret key is generated. This key is then used to encrypt the email content using the AES-256 cipher, rendering it unreadable to anyone without the key.
- Individual ECIES Encryption: For Bob, a unique encrypted copy of the email is created. The secret key used in the previous step is itself encrypted using Bob's public key, using the ECIES algorithm. This ensures that only Bob, with his corresponding private key, can decrypt the secret key and the email content.
- Recipient List and Unique Keys: A recipient list is generated, where each recipient (in this case, just Bob) has a corresponding unique key (the encrypted secret from step 3) associated with them. This key is essential for them to unlock the email.
- Secure SMTP Transmission: The encrypted email, along with the individually encrypted secret key for Bob, is sent via SMTP. Importantly, each recipient receives their own unique, encrypted version of the email, inaccessible to anyone else, even during transit.
- Recipient Receives: Bob receives his copy of the encrypted email.
- Private Key Decryption: Using his private key, Bob decrypts the secret key that was encrypted specifically for him.
- Content Decryption with AES-256: With the decrypted secret key, Bob can now unlock the email content using AES-256, revealing the original message.
- Seamless Reading: Bob can now read Alice's email, assured of its confidentiality and integrity.
Importantly, this entire process occurs automatically. Users don't need to manually handle keys or perform any complex cryptographic operations. Atomic Encryption provides seamless, robust end-to-end encryption without compromising user experience. This is true security without complexity.
Sending E2EE Emails to External Providers
What happens when you need to send an encrypted email to someone who uses another email provider? We've developed a robust solution for this case as well, ensuring your sensitive information remains protected even when communicating with users on other platforms that may not even support encryption. Here's how it works:
- Compose: Alice writes her email and selects "Password Encryption." She sets a password and a helpful hint for the recipient. This password is the key to unlocking the encrypted email.
- Local AES-256-CBC Encryption: On Alice's device, the email content is encrypted using AES-256-CBC. This ensures that the content is secure before it even leaves Alice's device. Importantly, the encryption key is derived from the password using Scrypt, a key derivation function that makes it significantly harder for attackers to crack the password.
- Secure Storage in Decryption Service: The encrypted email is then stored in a secure Decryption Service. No one, not even Atomic Mail, has access to the encrypted content. It remains confidential until the recipient retrieves it or the set expiration date passes.
- SMTP Transmission with Unique Link: The recipient receives an email with a unique link to the Decryption Service. The email content itself is not included in the email, ensuring it remains protected during transit.
- Recipient Decryption: The recipient clicks the link, enters the password provided by Alice, and the email content is decrypted locally on their device using AES-256-CBC. This ensures that the decryption process happens on the recipient's side, maintaining confidentiality.
Key Advantages:
- End-to-End Security: Even though the recipient uses a traditional email service that doesn't support modern encryption standards, the email content remains encrypted throughout the entire process. Your data remains protected regardless of the recipient's email provider.
- User-Friendly: The process is simple and intuitive for both the sender and the recipient.
- Zero-Knowledge System: Atomic Mail has no access to the email content or the password, ensuring complete privacy.
Zero-Access Encryption. How We Guarantee That Even Atomic Mail Cannot Access Your Data
At Atomic Mail, we believe that true privacy means you – and only you – should have access to your data. That’s why we’ve built our platform on a zero-access encryption model. While end-to-end encryption protects your data in transit, zero-access encryption safeguards it while it's stored on our servers.
We achieve this through:
- Client-Side Encryption: As mentioned previously, your data is encrypted on your device before it ever reaches our servers. Why does this matter? Because even if someone were to gain unauthorized access to our servers (an unlikely scenario given our security measures), your data would remain inaccessible to attackers.
- Server-Side Storage Without Decryption Keys: Once the encrypted data arrives on our servers, it remains in its encrypted state. Unlike other providers who may store unencrypted copies of your emails, we ensure that decryption keys are never stored alongside your data. Instead, these keys reside securely on your device or in your personal key management system, such as the BIP39 seed phrase we provide during account setup.
- No Backdoors: Unlike some email providers and companies that may comply with requests to access user data, Atomic Mail has no backdoors. We’ve designed our system so that even we can’t bypass your encryption.
- Regular Security Audits: Our systems undergo regular security audits by independent third-party experts to ensure compliance with the highest security standards.
How Does This Protect You?
Let's illustrate the power of zero-access encryption with a practical example. Imagine a scenario where a cybercriminal manages to breach Atomic Mail's servers. Despite their efforts, they would hit a wall. Why? Because your data isn't just encrypted – it's encrypted with keys that we simply don't possess. All they would gain access to is a collection of ciphertext – meaningless data without the decryption keys, which reside solely with you.
This level of protection isn't just a theoretical concept or marketing jargon. It's a real-world implementation of advanced cryptography, designed to withstand even the most determined and sophisticated attacks.
We believe that zero-access encryption is the future of online security. It's a paradigm shift that puts users in complete control of their data. By implementing this model, we are not only protecting your privacy but also setting a new standard for the industry.
