FLASH ENCRYPTION

SWF files are encrypted using the FIPS approved algorithm, AES at its strongest strength, 256 bit. For more information on the AES alogrithm see FIPS-197.

FLASH DECRYPTION

Encrypted SWF files are decrypted on-the-fly entirely under our own control in the flash security player.

Decrypted content is never stored to disk in temporary files or in the Windows swap file.

Javascript is not supported to prevent malicious code execution - see Adobe Flash security issues. We do not rely upon other implementations, or plug-ins that can be subverted, or clash with plug-ins provided by other suppliers.

PUBLIC KEY TECHNOLOGY

We use strong public key technology rather than weak password mechanisms that are easily crackable. Since there are no passwords to enter the system is not vulnerable to password attacks. Decryption keys are transparently relayed to the client computer and stored in encrypted format. There are no passwords to enter, manage, compromise, forget or pass on to others.

All communication between the client and the server is encrypted in order to prevent an attacker from being able to observe the secure exchanges between the client and the administration system. Where key material is being exchanged it is encrypted prior to being sent using a DH exchange at 2048 bits. This avoids the possibility of theoretical attacks where the attacker may observe in excess of 1.5 million messages.

KEY MANAGEMENT

Whilst we use public key technology, no key management is required by you as the publisher or by your users or customers, as it is all handled transparently by the licensing system. There are no certificates to revoke when you want to terminate a customers access or any other PKI complexity.

LICENSE CONTROL

We do not create extra files on disk that can be copied to another computer along with the protected files so they can be easily shared and viewed.
