Samsung SAS 12G TCG Enterprise SSC SEDs PM1633 Security Policy Introduction Samsung SAS 12G TCG Enterprise SSC SED PM1633, herein after referred to as a "cryptographic module" or "module", is a FIPS 140-2 Level 2 SSD (Solid State Drive), supporting TCG Enterprise SSC based SED (Self-Encrypting Drive) features, designed to protect unauthorized access to the user data stored in its NAND Flash memories. The built-in AES HW engines in the cryptographic module's controller provide on-the-fly encryption and decryption of the user data without performance loss. The SED's nature also provides instantaneous sanitization of the user data via cryptographic erase.

Cryptographic Boundary The following photographs show the cryptographic module's top and bottom views. The multiple-chip standalone cryptographic module consists of hardware and firmware components that are all enclosed in two aluminum alloy cases, which serve as the cryptographic boundary of the module. The top and bottom cases are assembled by screws and the tamper-evident labels are applied for the detection of any opening of the cases. No security relevant component can be seen within the visible spectrum through the opaque enclosure.

Samsung SAS 12G TCG Enterprise SSC SEDs PM1633 Security Policy Approved Algorithms The cryptographic module supports the following Approved algorithms for secure data storage: AES-256 ECB and XTS modes: AES (Cert. #3213) ECDSA (P-224 with SHA-256) Signature Verification: ECDSA (Cert. #595) SHA-256: SHS (Cert. #2660) CTR_DRBG (AES-256 with No_Df): DRBG (Cert. #121) NOTE: The cryptographic module implements LSI Corporation's LSI-CS DRBG in its entirety without alteration. Silicon for LSI-CS did not exist at the time of Algorithm Testing, therefore testing was carried out by LSI in a Synopsys VCS simulation environment. Non-Approved Algorithms The cryptographic module supports the following non-Approved algorithms allowed in the FIPS Approved mode of operation: Non-deterministic Random Number Generator (only used for generating seed materials for the Approved DRBG): NDRNG Physical Ports and Logical Interfaces Physical Port Logical Interface Data Input/Output SAS Connector Control Input Status Output Power Connector Power Input Exhibit 6 ­ Specification of the Samsung SAS 12G TCG Enterprise SSC SED PM1633 Cryptographic Module Physical Ports and Logical Interfaces. Security rules The following specifies the security rules under which the cryptographic module shall operate in accordance with FIPS 140-2: The cryptographic module only operates in a FIPS Approved mode of operation. The module is shipped in the FIPS Approved mode of operation from the vendor's manufacturing site. The cryptographic module is initialized for FIPS Mode by performing the following procedure: o Power-on the module Page 7 of 15 This non-proprietary Security Policy may only be copied in its entirety without alterations including this statement. Samsung copyright 2015. Samsung SAS 12G TCG Enterprise SSC SEDs PM1633 Security Policy o Confirm that the firmware version is equivalent to the version(s) listed in this document via SCSI command o Perform Initialization service (See the product manual) The cryptographic module shall maintain logical separation of data input, data output, control input, status output, and power. The cryptographic module shall not output CSPs in any form. The cryptographic module shall use the Approved DRBG for generating all cryptographic keys. The cryptographic module shall enforce role-based authentication for security relevant services. The cryptographic module shall enforce a limited operational environment by the secure firmware load test using ECDSA P-224 with SHA-256. The cryptographic module shall provide a production-grade, opaque, and tamper-evident cryptographic boundary. The cryptographic module enters the error state upon failure of Self-tests. All commands from the Host (General Purpose Computer (GPC) outside the cryptographic boundary) are rejected in the error state and the cryptographic module returns an error code (0x91) via the status output. Cryptographic services and data output are explicitly inhibited when in the error state.

Samsung SAS 12G TCG Enterprise SSC SEDs PM1633 Security Policy Identification and Authentication Policy The following table defines the roles, type of authentication, and associated authenticated data types supported by the cryptographic module: Role Authentication Data CO Role Password User Role Password FW Loader ECDSA Exhibit 7 - Roles and Required Identification and Authentication (FIPS 140-2 Table C1). The authentication mechanism allows 6-byte length or longer Password, where each byte can be any of 0x00 to 0xFF, for every Cryptographic Officer and User role supported by the module, which means a single random attempt can succeed with the probability of 1/248 or lower. Each authentication attempt takes at least 56ms and the number of attempts is limited to TryLimit, which is set to 5 in manufacturing time. Since the module takes at least 8 seconds to be ready after power-on and 5 authentication failures require a power-cycle, it takes 8280ms for every 5th authentication attempt. Therefore, the probability of multiple random attempts to succeed in one minute is {(60*1000)/(8280/5)}/248, which is much less than the FIPS 140-2 requirement 1/100,000. The authentication mechanism for FW Loader role is ECDSA P-224 with SHA256 digital signature verification, which means a single random attempt, can succeed with the probability of 1/2112. Each authentication attempt takes at least 2 seconds, which enforces the maximum number of attempts to be no more than (60*1000)/2000 in one minute. Therefore, the probability of multiple random attempts to succeed in one minute is {(60*1000)/2000}/2112, which is much less than the FIPS 140-2 requirement 1/100,000.

Samsung SAS 12G TCG Enterprise SSC SEDs PM1633 Security Policy Physical Security Policy The following physical security mechanisms are implemented in a cryptographic module: The Module consists of production-grade components enclosed in an aluminum alloy enclosure, which is opaque within the visible spectrum. The top panel of the enclosure can be removed by unscrewing screws. However, the module is sealed with tamper-evident labels in accordance with FIPS 140-2 Level 2 Physical Security requirements so that tampering is easily detected when the top and bottom cases are detached. QTY. 2 tamper-evident labels are applied over both top and bottom cases of the module at the factory. The tamper-evident labels are not removed and reapplied without tamper evidence. The following table summarizes the actions required by the Cryptographic Officer Role to ensure that physical security is maintained: Recommended Physical Security Frequency of Inspection/Test Guidance Details Mechanisms Inspection/Test Inspect the entire perimeter for cracks, Production gouges, lack of screw(s) and other signs of grade Cases tampering. Remove from service if As often as feasible tampering found. Inspect the sealing labels for scratches, Tamper-evident gouges, cuts and other signs of tampering. Sealing Labels Remove from service if tampering found.
