Encryption keys are security mechanisms used to protect transaction data as it moves between financial institutions and switching platforms. They help ensure that sensitive information remains confidential, authentic, during transmission.
Why Encryption Keys Are Important
Encryption keys play a critical role in securing digital transactions by:
Protecting transaction data from unauthorized access
Ensuring data integrity during transmission
Supporting compliance with industry security standards
Reducing the risk of fraud and data interception
By using encryption keys, institutions can exchange transaction information with confidence, knowing that data is protected end-to-end.
How Encryption Keys Are Used
To establish secure communication, both parties exchange public encryption keys. These keys are used to encrypt and verify transaction messages exchanged between systems. This process helps ensure that only authorized parties can read or validate the information being shared.
Managing Encryption Keys
Authorized users within an institution are responsible for managing encryption keys. This typically includes:
Uploading the institution’s public encryption key
Downloading the platform’s public encryption key when required
Ensuring keys are kept up to date in line with security policies
Proper key management helps maintain uninterrupted and secure transaction processing.
Security Best Practices
To maintain a secure environment, institutions should:
Restrict encryption key management to authorized users only
Follow internal security and compliance guidelines
Update encryption keys when required
Avoid sharing encryption keys through unsecured channels
