Hardware Security Module (HSM)
HSMs are a crucial component of the security framework of ARMswap. These are physical devices that handle and protect cryptographic keys. Their main function is to ensure the security and reliability of every transaction signing that takes place.
HSMs are responsible for providing important security functions for our platform.
- Key Protection: HSMs store cryptographic keys or passwords that are necessary for performing transactions. Moreover, they protect them from being hacked or cracked.
- Transaction Verification: Every transaction is verified by these HSMs before they are processed.
- Isolation: HSMs operate separately from the main system. However, they ensure the keys or passwords remain secure even if the platform is compromised or disrupted.
Process Flow for Cross-Chain Bridging Using HSM
Swap/Bridge
First of all, the user selects the assets and blockchain networks to start the swap. For example, the user will select 5 ETH (an asset) from Ethereum blockchain to Binance Smart Chain.
Transaction Authorisation with HSM
The platform then generates a request for HSM to sign the transaction.
Transaction Signing & Encryption
After signing the transaction, HSM encrypts all related data.
Validation and Completion
Both the blockchains validate the transactions to ensure secure transfers.
What is HSM?
A Hardware Security Module (HSM) is a device that is used to manage, process, and secure cryptographic keys or passwords.
These devices have been widely used in banks and other businesses for a long time. Nowadays, they also play an important role in decentralized blockchain networks.
HSMs are designed to protect and secure the private keys or passwords that are necessary for transactions in cross-chain platforms like ARMswap.
These are like digital cellars that keep important passwords to perform asset transfers across cross-chain platforms. These digital boxes also help prevent unauthorized access or misuse.
How HSM Works in a Cross-Chain Platform
When a user wants to transfer data across different blockchains, the cross-chain platforms act as a “bridge” in executing seamless transactions.
A step-by-step process on how HSMs work in a cross-chain platform is given below:
- Initiation of Swap: A user initiates the swap process on the platform, specifying the details of the transaction, such as the amount and destination blockchain.
- Processing of Request: The platform processes the request and prepares the transaction details.
- Key Generation and Management: When the platform is set up, an HSM (Hardware Security Module) generates a secure set of cryptographic keys. These keys are stored and managed exclusively within the HSM, ensuring that they remain protected and cannot be accessed externally. Each transaction uses these keys to maintain secure interactions between chains.
- Role of HSM in Secure Signing: Once the transaction details are ready, they are sent to the HSM, where the secure signing process begins. The HSM uses its private key to cryptographically sign the transaction. This process ensures that the transaction is authentic and cannot be tampered with.
- Verification of Integrity: The HSM verifies the transaction's integrity, checking for any signs of modification or inconsistency in the transaction data before it moves forward.
- Execution of Transfer: After the HSM completes the signing and verification process, it sends the signed transaction back to the platform, which then executes the transfer on the target blockchain, ensuring secure and seamless cross-chain interaction.
Commitment to Continuous Improvement
Security is not a one-time effort but an ongoing commitment. At ARMswap, we continuously strive to enhance our security measures and stay ahead of potential threats. Here’s how we maintain and improve our security posture:
- Proactive Monitoring: Our team monitors the platform 24/7 to detect and respond to any security incidents swiftly.
- Bug Bounty Program: We invite independent security researchers to test our system through our Bug Bounty Program, rewarding them for identifying vulnerabilities.
- User Education: We believe in empowering our users with knowledge. We regularly publish security tips and best practices to help users protect their accounts and assets.
User Responsibility and Best Practices
While we implement robust security measures, user cooperation is vital to maintaining a secure environment. Here are some best practices we recommend:
- Enable MFA: Always enable multi-factor authentication to add an extra layer of security to your account.
- Use Strong Passwords: Create strong, unique passwords for your accounts and change them regularly.
- Stay Informed: Keep up to date with the latest security news and updates from ARMswap.
- Report Suspicious Activity: If you notice any suspicious activity on your account, report it to us immediately.
