Say goodbye to paper trails, manual data entry, and potential errors. This innovative technology allows for seamless electronic communication and data exchange between trading partners, making it an invaluable tool for streamlining your supply chain, reducing costs, and improving overall efficiency. From automating order processing to enhancing inventory management.
History of AS2
The AS2 protocol was developed in the late 1990s by the Internet Engineering Task Force (IETF), in response to the need for secure data exchange without relying on traditional methods.
In 2002, the protocol gained significant traction when Walmart, one of the world’s largest retailers, mandated AS2 for its suppliers. This requirement created a wave of AS2 adoption, which spread across various industries.
Over time, AS2 became an EDI standard endorsed by numerous organizations, setting the foundation for modern, internet-based data exchange methods.
What is AS2?
AS2, or Applicability Statement 2, is a protocol that allows the secure and dependable transfer of data over the Internet. The use of AS2 allows organizations to establish direct connections with their trading partners, creating a more streamlined communication channel.
Originally designed to enable secure EDI transactions, AS2 has gained popularity due to its encryption capabilities, which help protect sensitive data during transmission. The protocol uses secure HTTP (HTTPS) as the transport layer and supports digital certificates for encryption and digital signatures for data integrity.
This ensures that files sent via AS2 reach their intended recipient without tampering or unauthorized access. The enhanced security measures provided by AS2 also help businesses comply with industry regulations, thus avoiding potential fines and maintaining a trustworthy reputation.
AS2 protocol is designed with three core features security, integrity, and non-reputation
- Security:Sensitive data is protected in AS2 through the transport layer which wraps EDI data in a secure “envelope” and sends it over the internet.
- Integrity: The data is encrypted, and the identity of the sender and the integrity of the payload are ensured using pre-established digital certificates that are validated upon each connection.
- Non-Reputation: The receiver of the data returns a signed message containing a Message Disposition Notification (MDN) confirming the successful transfer.
A simple AS2 setup involves two computers – a client and a server – connecting in a point-to-point manner via the web. Sending EDI documents via AS2 requires the receiving organization’s server to be always ‘listening”. Like a call to a phone without an answering machine, the message will be missing if the AS2 server is not available. As a result of this high availability requirement, many businesses prefer to use an EDI provider to help them with EDI AS2 integration and provide ongoing maintenance and support.
Traditional methods of data exchange, such as email, fax, or FTP, can be susceptible to data loss or corruption. In contrast, AS2 ensures that every message is acknowledged and validated upon receipt, providing a clear audit trail. This level of reliability is crucial for maintaining accurate records and ensuring compliance with industry regulations. Companies can have confidence that their transactions are executed correctly, and that sensitive information remains protected.
What are the Key Attributes of the AS2 Protocol?
The AS2 protocol has several defining attributes that make it a popular choice for secure data exchange:
- Security: AS2 uses encryption and digital signatures to secure data, making it one of the safest methods for transferring sensitive information over the internet.
- Authentication: By verifying the sender’s identity using digital certificates, AS2 ensures that files come from trusted sources.
- Non-Repudiation: AS2 provides proof of delivery through Message Disposition Notifications (MDNs), which serve as receipts that confirm a successful transfer. This feature is essential for industries where compliance and accountability are crucial.
- Data Integrity: With AS2, files cannot be modified during transmission. The protocol employs cryptographic hashing to confirm that the data sent matches the data received.
- Real-Time Exchange: Unlike traditional VANs, AS2 facilitates direct, real-time data transfer, which enhances communication speed and operational efficiency.
- Cost-Effective: AS2 allows businesses to bypass intermediaries like VANs, reducing transaction costs and giving organizations greater control over data exchanges.
Who Uses AS2?
AS2 is widely used by companies that need to exchange sensitive data securely and efficiently. This includes sectors like:
- Retail: Large retail chains, like Walmart, require suppliers to use AS2 to ensure fast, secure, and reliable transactions.
- Manufacturing: Many manufacturing firms use AS2 to exchange supply chain information, such as order details, invoices, and shipping updates.
- Healthcare: Hospitals and healthcare providers rely on AS2 to transmit time sensitive information in compliance with regulations.
- Logistics and Transportation: AS2 is essential for logistics companies that handle various EDI documents, including shipping manifests, to ensure smooth operations.
- Government Agencies: Certain government agencies and contractors use AS2 to securely transmit official documents.
How do I Send and Receive EDI Files via AS2?
Step 1 – EDI Document Preparation
Documents are prepared in a standard EDI format to be sent over AS2
Step 2 – AS2 Packaging
The document is packaged to send via AS2 using three layers of transmission:
Compression – A document may be compressed using a compression algorithm to reduce the size of the data being transferred
Signature – Sender signs the document using the exchanged certificates and keys to ensure data integrity
Encryption – The data is typically encrypted using the receiver’s public encryption key, so only the proper recipient will be able to extract the document
Step 3 – Message Delivery
The data is transmitted securely over HTTP/S. A Message Disposition Notification (MDN) is returned to the sender confirming receipt.
Step 4 – AS2 Unpacking
Upon receiving the document at the receiver’s end, the document is decrypted using the receiver’s private key and then verified by using the sender’s public key and finally the document will be decompressed
Step 5 – EDI Processing
The document is then passed by the AS2 receiver system to any backend process that handles the data. The next systems and workflows perform any additional business logic and make the document available to business users.
Step 6 – Confirmation of Receipt
The receiving organization uses AS2 or EDI software to extract the message and send message confirmation receipts such as the MDN and EDI functional acknowledgment (997) to the sender.
Step 7 – Sender Validation (MDN processing)
The sender receives the MDN and validates the receipt signature and completes any other configured data integrity checks that confirm the successful delivery transaction.
