Supported Standards

Meeco is actively following, and where possible, contributing in standardisation efforts of the leading groups in the identity and personal data space. This page lists the currently supported standards within the Secure Value Exchange (SVX) platform.

• European Blockchain (EBSI)

• HBAR Foundation

• Internet Assigned Numbers Authority (IANA)

• Internet Engineering Task Force (IETF)

• OpenID Foundation (OIDF)

Supported Algorithms

JWS Signature

The following key types are supported for JWS verification. The subset of supported "JWS Algorithms" are part of IANA - JSON Web Signature Algorithms registry.

JWS Algorithm	Key Type
ES256	ECDSA using P-256 and SHA-256
ES256K	ECDSA using secp256k1 and SHA-256
EdDSA	EdDSA using Ed25519 and SHA-256

Master Encryption Key Algorithms

The following algorithms are supported when generating derived keys. Used as defined in NIST - Master Key.

Key Type
PBKDF2HMAC

Key Encryption Algorithms

The following algorithms are supported when encrypting other keys at rest and in transit. Used as defined in NIST - Key-Encryption-Key.

Key Type
AES-256-GCM

Keypairs

The following keypair algorithms are supported for exchanging keys between parties. Used as defined in NIST - Key pair.

Key Type
RSA-4096

Data Encryption Algorithms

The following algorithms are supported when encrypting data at rest and in transit. Used as defined in NIST - Data Encryption Key.

Key Type
AES-256-GCM

Supported OAuth Authentication Flows

The following flows are supported by SVX:

OAuth Code Flow & PKCE

The Portal uses a code flow in conjunction with Proof Key for Code Exchange (PKCE) for secure authentication of users (Administrators) logging into the Portal.

Client Credentials Flow

Organisations building services on top of the SVX API can use the Portal to create an application to enable machine-to-machine communication. The application allows access to a Client ID and Secret to perform the client credentials flow. The access token enables organisations to access the resources linked to that organisation.
