include the ukm. As specified in RFC 3852 [CMS], implementations
MUST support ukm message recipient processing, so
interoperability is not a concern if the ukm is present or
absent. When present, the ukm is used to ensure that a

ephemeral private key is improperly used more than once, by
using the ECC-Shared-Info as input to in the key derivation

key for each recipient. The RecipientEncryptedKey
KeyAgreeRecipientIdentifier MUST contain either the
issuerAndSerialNumber identifying the recipient's certificate or
the RecipientKeyIdentifier containing the subject key identifier
from the recipient's certificate. In both cases, the
recipient's certificate contains the recipient's static ECDH
public key. RecipientEncryptedKey EncryptedKey MUST contain the

Cryptographic algorithms will be broken or weakened over time. Cryptographic algorithms will be broken or weakened over time.
Implementers and users need to check that the cryptographic Implementers and users need to check that the cryptographic
algorithms listed in this document continue to provide the expected algorithms listed in this document continue to provide the expected
level of security. The IETF from time to time may issue documents level of security. The IETF from time to time may issue documents
dealing with the current state of the art. dealing with the current state of the art.
This specification is based on [CMS], [CMS-AUTHENV], [CMS-ALG], [CMS- Cryptographic algorithms rely on random number. See [RANDOM] for
AESCG], [X9.62], and [SEC1] and the appropriate security guidance on generation of random numbers.
Receiving agents that validate signatures and sending agents that
encrypt messages, need to be cautious of cryptographic processing
usage when validating signatures and encrypting messages using keys
larger than those mandated in this specification. An attacker could
send certificates with keys which would result in excessive
cryptographic processing, for example keys larger than those mandated
in this specification, which could swamp the processing element.
Agents which use such keys without first validating the certificate
to a trust anchor are advised to have some sort of cryptographic
resource management system to prevent such attacks.
Using secret keys of an appropriate size is crucial to the security
of a Diffie-Hellman exchange. For elliptic curve groups, the size of
the secret key must be equal to the size of n (the order of the group
generated by the point g). Using larger secret keys provides
absolutely no additional security, and using smaller secret keys is
likely to result in dramatically less security. (See [SP800-56A] for
more information on selecting secret keys.)
This specification is based on [CMS], [CMS-AUTHENV], [CMS-ALG],
[CMS-AESCG], [X9.62], [SEC1], and [SEC2] and the appropriate security
considerations of those documents apply. considerations of those documents apply.
In addition, implementors of AuthenticatedData should be aware of the In addition, implementors of AuthenticatedData should be aware of the
concerns expressed in [BON] when using AuthenticatedData to send concerns expressed in [BON] when using AuthenticatedData to send
messages to more than one recipient. Also, users of MQV should be messages to more than one recipient. Also, users of MQV should be
aware of the vulnerability in [K]. aware of the vulnerability in [K].
