Summary | 0009013: Unclear and/or misleading wording in the ECC Amendment - Need to describe the EccEncryptedSecret Signature for AEAD Ciphers | ||||
Description | I refer to this document: https://reference.opcfoundation.org/src/v104/Core/docs/Amendment4/readme.htm I think we should state that in the case of ChaCha20-Poly1305, there This second signature could be omitted, making this a ChaCha20 cipher. Suggested fix: Change the spec? | ||||

|
Part 4 Table 190 – EccEncryptedSecret Layout Need text to explain that when using authenticated symmetric encryption (ChaCha20-Poly1305) includes a symmetric signature which is incorporated after the bytes of the secret+padding. (i.e. their should be another row after the padding for authenticated encryption signature). The text needs to state that only the secret+padding is included in the signature calculation (i.e. no additional data). |
|
Added text to table: When using AuthenticatedEncryption the Signature has 2 parts: the Signature produced when the secret is encrypted using the SymmetricEncryptionAlgorithm and the Signature calculated using the Certificate and the AsymmetricSignatureAlgorithm. Both Signatures are calculated from the start of the packet. The AsymmetricSignatureAlgorithm Signature includes the SymmetricEncryptionAlgorithm Signature. |
