The Internet's architecture offers unlimited opportunities for unscrupulous people to intercept and replace data captured in transit. Without security precautions in place, each transaction or transmission may be compromised when sending information over the Internet or an intranet. This vulnerability has serious implications for the security of Internet commerce—there must be a means to secure and transmit data—iaSecure is a unique solution to this problem.

iaSecure protects data and digital content transfers by utilizing four pillars of digital security:

Privacy: Encrypts data so that only entities that know the key used to encrypt can decrypt and read the data.
Encryption ensures data cannot be read or used by any party during transit. iaSecure translates a message into incomprehensible binary characters before it leaves the sender's computer. The message maintains its encrypted state while traveling through the Internet. It is decrypted only when received by the intended recipient and the sender's identity is verified. Ia's proprietary digital enveloping methods ensure only the intended recipient can decrypt message.

Authentication: Assures that the identities of all parties to the transaction and transmission are valid.
iaSecure provides digital verification of the sender and receiver—much like a driver's license verifies identity. Anyone can communicate with anyone in the world by pretending they are someone else—this is called spoofing. There is no way to verify a sender's identify using standard security protocols. iaSecure's digital envelope and signature technology provides digitally encoded and verifiable proof of identity.

Integrity: Assures that the data was not tampered with during transit—the receiver receives exactly what the sender sent.
Data integrity proves the data sent has not been altered during transmission. Information travels across the Internet through various gateways where it becomes vulnerable to capture, alteration, and resending. For example, someone can intercept a payment made to a credit card company and reroute the credit payment to a different account. iaSecure ensures the data integrity and a message cannot be altered without the recipient's knowledge.

Nonrepudiation/Sender Verification: Assures that the sender cannot deny sending a file and the receiver cannot deny receiving a file/data.
A sender cannot falsely deny that a message was sent; neither can a receiver deny a message arrived.

The iaSecure system uses pass phrases and other user-specific information to replace the traditional unsecured password, which can be easily guessed. This approach virtually eliminates standard password hacking. Ia incorporates a hybrid cryptographic approach. Instead of using a password for an encryption key, iaSecure uses a dynamic key approach featuring a blend of symmetric and asymmetric paradigms. The one-time keys will never be used again.

iaSecure also uses digital signatures—based on the user's private key—to digitally sign the hash of the transaction message. It then encrypts this information in a digital envelope that is sent through the Internet, authorizing the intended recipient access. Once the digital envelope is received by the security server, it decrypts the digital envelope, retrieves the digital signature, and compares the hash with the decrypted message to verify the data's integrity.
