The primary purpose of the module is to decrypt, decode, and encode audio/video data for a digital cinema player. The cryptographic boundary is defined as being the perimeter of the printed circuit board. The components and areas of the printed circuit board not covered by the metallic case are excluded from the requirements of FIPS 140-2, because they are non-security relevant. This document refers specifically to the CAT904 Dolby JPEG 2000/MPEG-2 Processor hardware P/N CAT904Z revision FIPS_1.0, FIPS_1.0.1, FIPS_1.0.2 and FIPS_1.1 running firmware version 1.3.4.21.

The Cryptographic Officer is assumed by Dolby Laboratories and the User is assumed by the Show Store. The cryptographic module shall enforce the separation of roles using identity-based operator authentication by means of digital signatures. Table 4 Roles and Required Identification and Authentication Role Type of Authentication Authentication Data Digital Signature Verification Identity-based operator User using Show Store Root Public authentication Key Digital Signature Verification Identity-based operator Cryptographic Officer using Dolby Maintenance authentication Public Key Table 5 Strengths of Authentication Mechanisms Authentication Mechanism Strength of Mechanism The probability that a random attempt will succeed or a false acceptance will occur is 1/2112 which is less than 1/1,000,000. The probability of successfully authenticating RSA 2048-bit Digital Signature verification to the module within one minute through random attempts is 200/2112 (due to timing limitations in the module) which is less than 1/100,000. 4 ® Dolby Laboratories CAT904 Dolby JPEG 2000/MPEG-2 Processor Security Policy Version 1.3 7 Access Control Policy Roles and Services Table 6 Services Authorized for Roles Role Authorized Services Execute Key Delivery Message (KDM): Execute KDM, which includes the loading of an RSA wrapped Content Key.

Three 64-bit random values are provided during manufacturing to account for a maximum of 192-bits of uncertainty. 10 ® Dolby Laboratories CAT904 Dolby JPEG 2000/MPEG-2 Processor Security Policy Version 1.3 10 Physical Security Policy Physical Security Mechanisms The CAT904 Dolby JPEG 2000/MPEG-2 Processor includes the following physical security mechanisms:  Production-grade components and production-grade opaque metal enclosure.  Metal enclosure with automatic zeroization when enclosure is opened via tamper detection and zeroization circuitry.  Enclosure cover screws are protected with tamper-evident expansion plugs. 11 Mitigation of Other Attacks Policy The module has not been designed to mitigate specific attacks beyond the scope of FIPS 140-2 requirements. 11
