| | IANA Registration for Enumservice UNUSED |
| |
|
This document registers the Enumservice "unused" using the URI scheme "http:" as per the IANA registration process defined in the ENUM specification, RFC 3761. This Enumservice may be used to indicate that the E.164 number (or E.164 number range) tied to the domain in which the enclosing NAPTR is published is not allocated or assigned for communications service. When such an indication is provided, an ENUM client can detect calls that will fail "early". |

| | Multiple Signatures in S/MIME |
| |
|
Cryptographic Message Syntax (CMS) SignedData includes the SignerInfo structure to convey per-signer information. SignedData supports multiple signers and multiple signature algorithms per-signer with multiple SignerInfo structures. If a signer attaches more than one SignerInfo, there are concerns that an attacker could perform a downgrade attack by removing the SignerInfo(s) with the 'strong' algorithm(s). This document defines the multiple-signatures attribute, its generation rules, and its processing rules to allow signers to convey multiple SignerInfo while protecting against downgrade attacks. Additionally, this attribute may assist during periods of algorithm migration. |
