1. Introduction
Mandatory algorithms may change over time due to an evolving threat landscape. As a result these are grouped into profiles that a device should use.¶
the mandatory-to implement algorithms for SUIT are described in this draft in order to provide flexibility in the definition of algorithm profiles.¶
An authentication algorithm is REQUIRED for ALL SUIT manifests. Encryption algorithms MAY be provided.¶
2. Algorithms
The algorithms that form a part of the profiles defined in this document are grouped into:¶
2.2. Authentication Algorithms
Authentication Algorithms are divided into three categories:¶
2.3. Key Exchange Algorithms
Key Exchange Algorithms are divided into two three groups: Symmetric, Classical Asymmetric, and Post-Quantum Asymmetric¶
2.3.3. Post-Quantum Asymmetric
- CRYSTALS-KYBER (TBD)¶
3. Profiles
The following profiles are defined by this draft:¶
5. IANA Considerations
TODO¶
