Issue Description

FCS-COP.1(3) within the ESM Protection Profiles is limited to SHA1, SHA256, and SHA384. This needs to be expanded to include SHA512.

 

The wording currently Reads:

FCS_COP.1(3) Cryptographic Operation (for Cryptographic Hashing)

 

Hierarchical to: No other components.

FCS_COP.1.1(3) Refinement: The TSF shall perform cryptographic hashing services in accordance with a specified cryptographic algorithm [selection: SHA-1, SHA-256, SHA-384] and message digest sizes [selection: 160, 256, 384] bits that meet the following: FIPS Pub 180-3, “Secure Hash Standard.”

Resolution

The wording is being revised to:

FCS_COP.1(3) Cryptographic Operation (for Cryptographic Hashing)

 

Hierarchical to: No other components.

FCS_COP.1.1(3) Refinement: The TSF shall perform cryptographic hashing services in accordance with a specified cryptographic algorithm [selection: SHA-1, SHA-256, SHA-384, SHA512] and message digest sizes [selection: 160, 256, 384, 512] bits that meet the following: FIPS Pub 180-3, “Secure Hash Standard.”

Justification

The SHA512 algorithm is suitable for use and being added as a selection.
