Opus provides integrity and confidentiality protection of its memory. This protection is cryptographically strong, and the memory data transmitted from the Opus device can be trusted anywhere the data travels wirelessly on the earth. With Opus, secure remote monitoring and automation of data sampling and processing are made possible.

The integrity and confidentiality protection framework is provided by the GEN2V2 optional command Authenticate. Any reader supporting Authenticate, since supporting the command is optional, can initiate the security functions inside the protection framework and solicit memory information, but only can the entity possessing the keys verify whether the information is trustworthy.
