RFC3547 - The Group Domain of Interpretation: This document presents an ISAMKP Domain of Interpretation (DOI) for group key management to support secure group communications. The GDOI manages group security associations, which are used by IPSEC and potentially other data security protocols running at the IP or application layers. These security associations protect one or more key-encrypting keys, traffic-encrypting keys, or data shared by group members. [STANDARDS-TRACK]
RFC3740 - The Multicast Group Security Architecture: This document provides an overview and rationale of the multicast security architecture used to secure data packets of large multicast groups. The document begins by introducing a Multicast Security Reference Framework, and proceeds to identify the security services that may be part of a secure multicast solution. This memo provides information for the Internet community.
RFC3830 - MIKEY: Multimedia Internet KEYing: This document describes a key management scheme that can be used for real-time applications (both for peer-to-peer communication and group communication). In particular, its use to support the Secure Real-time Transport Protocol is described in detail. Security protocols for real-time multimedia applications have started to appear. This has brought forward the need for a key management solution to support these protocols. [STANDARDS-TRACK]
RFC4046 - Multicast Security (MSEC) Group Key Management Architecture: This document defines the common architecture for Multicast Security (MSEC) key management protocols to support a variety of application, transport, and network layer security protocols. It also defines the group security association (GSA), and describes the key management protocols that help establish a GSA. The framework and guidelines described in this document permit a modular and flexible design of group key management protocols for a variety of different settings that are specialized to applications needs. MSEC key management protocols may be used to facilitate secure one-to-many, many-to-many, or one-to-one communication. This memo provides information for the Internet community.
RFC4082 - Timed Efficient Stream Loss-Tolerant Authentication (TESLA): Multicast Source Authentication Transform Introduction: This document introduces Timed Efficient Stream Loss-tolerant Authentication (TESLA). TESLA allows all receivers to check the integrity and authenticate the source of each packet in multicast or broadcast data streams. TESLA requires no trust between receivers, uses low-cost operations per packet at both sender and receiver, can tolerate any level of loss without retransmissions, and requires no per-receiver state at the sender. TESLA can protect receivers against denial of service attacks in certain circumstances. Each receiver must be loosely time-synchronized with the source in order to verify messages, but otherwise receivers do not have to send any messages. TESLA alone cannot support non-repudiation of the data source to third parties.; This informational document is intended to assist in writing standardizable and secure specifications for protocols based on TESLA in different contexts. This memo provides information for the Internet community.
RFC4359 - The Use of RSA/SHA-1 Signatures within Encapsulating Security Payload (ESP) and Authentication Header (AH): This memo describes the use of the RSA digital signature algorithm as an authentication algorithm within the revised IP Encapsulating Security Payload (ESP) as described in RFC 4303 and the revised IP Authentication Header (AH) as described in RFC 4302. The use of a digital signature algorithm, such as RSA, provides data origin authentication in applications when a secret key method (e.g., HMAC) does not provide this property. One example is the use of ESP and AH to authenticate the sender of an IP multicast packet. [STANDARDS-TRACK]
RFC4383 - The Use of Timed Efficient Stream Loss-Tolerant Authentication (TESLA) in the Secure Real-time Transport Protocol (SRTP): This memo describes the use of the Timed Efficient Stream Loss-tolerant Authentication (RFC 4082) transform within the Secure Real-time Transport Protocol (SRTP), to provide data origin authentication for multicast and broadcast data streams. [STANDARDS-TRACK]
RFC4442 - Bootstrapping Timed Efficient Stream Loss-Tolerant Authentication (TESLA): TESLA, the Timed Efficient Stream Loss-tolerant Authentication protocol, provides source authentication in multicast scenarios. TESLA is an efficient protocol with low communication and computation overhead that scales to large numbers of receivers and also tolerates packet loss. TESLA is based on loose time synchronization between the sender and the receivers. Source authentication is realized in TESLA by using Message Authentication Code (MAC) chaining. The use of TESLA within the Secure Real-time Transport Protocol (SRTP) has been published, targeting multicast authentication in scenarios where SRTP is applied to protect the multimedia data. This solution assumes that TESLA parameters are made available by out-of-band mechanisms.; This document specifies payloads for the Multimedia Internet Keying (MIKEY) protocol for bootstrapping TESLA for source authentication of secure group communications using SRTP. TESLA may be bootstrapped using one of the MIKEY key management approaches, e.g., by using a digitally signed MIKEY message sent via unicast, multicast, or broadcast. [STANDARDS-TRACK]
RFC4534 - Group Security Policy Token v1: The Group Security Policy Token is a structure used to specify the security policy and configurable parameters for a cryptographic group, such as a secure multicast group. Because the security of a group is composed of the totality of multiple security services, mechanisms, and attributes throughout the communications infrastructure, an authenticatable representation of the features that must be supported throughout the system is needed to ensure consistent security. This document specifies the structure of such a token. [STANDARDS-TRACK]
RFC4535 - GSAKMP: Group Secure Association Key Management Protocol: This document specifies the Group Secure Association Key Management Protocol (GSAKMP). The GSAKMP provides a security framework for creating and managing cryptographic groups on a network. It provides mechanisms to disseminate group policy and authenticate users, rules to perform access control decisions during group establishment and recovery, capabilities to recover from the compromise of group members, delegation of group security functions, and capabilities to destroy the group. It also generates group keys. [STANDARDS-TRACK]
RFC4563 - The Key ID Information Type for the General Extension Payload in Multimedia Internet KEYing (MIKEY): This memo specifies a new Type (the Key ID Information Type) for the General Extension Payload in the Multimedia Internet KEYing (MIKEY) Protocol. This is used in, for example, the Multimedia Broadcast/Multicast Service specified in the Third Generation Partnership Project. [STANDARDS-TRACK]
RFC4650 - HMAC-Authenticated Diffie-Hellman for Multimedia Internet KEYing (MIKEY): This document describes a lightweight point-to-point key management protocol variant for the multimedia Internet keying (MIKEY) protocol MIKEY, as defined in RFC 3830. In particular, this variant deploys the classic Diffie-Hellman key agreement protocol for key establishment featuring perfect forward secrecy in conjunction with a keyed hash message authentication code for achieving mutual authentication and message integrity of the key management messages exchanged. This protocol addresses the security and performance constraints of multimedia key management in MIKEY. [STANDARDS-TRACK]
RFC4738 - MIKEY-RSA-R: An Additional Mode of Key Distribution in Multimedia Internet KEYing (MIKEY): The Multimedia Internet Keying (MIKEY) specification describes several modes of key distribution solution that address multimedia scenarios (e.g., SIP calls and Real Time Streaming Protocol (RTSP) sessions) using pre-shared keys, public keys, and optionally a Diffie-Hellman key exchange. In the public-key mode, the Initiator encrypts a random key with the Responder's public key and sends it to the Responder. In many communication scenarios, the Initiator may not know the Responder's public key, or in some cases the Responder's ID (e.g., call forwarding) in advance. We propose a new MIKEY mode that works well in such scenarios. This mode also enhances the group key management support in MIKEY; it supports member-initiated group key download (in contrast to group manager pushing the group keys to all members). This document updates RFC 3830 with the RSA-R mode. [STANDARDS-TRACK]
RFC5197 - On the Applicability of Various Multimedia Internet KEYing (MIKEY) Modes and Extensions: Multimedia Internet Keying (MIKEY) is a key management protocol that can be used for \%real-time applications. In particular, it has been defined focusing on the support of the Secure \%Real-time Transport Protocol (SRTP). MIKEY itself is standardized within RFC 3830 and defines four key distribution methods. Moreover, it is defined to allow extensions of the protocol. As MIKEY becomes more and more accepted, extensions to the base protocol arise, especially in terms of additional key distribution methods but also in terms of payload enhancements.; This document provides an overview about the MIKEY base document in general as well as the existing extensions for MIKEY, which have been defined or are in the process of definition. It is intended as an additional source of information for developers or architects to provide more insight in use case scenarios and motivations as well as advantages and disadvantages for the different key distribution schemes. The use cases discussed in this document are strongly related to dedicated SIP call scenarios providing challenges for key management in general, among them media before Session Description Protocol (SDP) answer, forking, and shared key conferencing. This memo provides information for the Internet community.
RFC5374 - Multicast Extensions to the Security Architecture for the Internet Protocol: The Security Architecture for the Internet Protocol describes security services for traffic at the IP layer. That architecture primarily defines services for Internet Protocol (IP) unicast packets. This document describes how the IPsec security services are applied to IP multicast packets. These extensions are relevant only for an IPsec implementation that supports multicast. [STANDARDS-TRACK]
RFC5776 - Use of Timed Efficient Stream Loss-Tolerant Authentication (TESLA) in the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) Protocols: This document details the Timed Efficient Stream \%Loss-Tolerant Authentication (TESLA) packet source authentication and packet integrity verification protocol and its integration within the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) content delivery protocols. This document only considers the authentication/integrity verification of the packets generated by the session's sender. The authentication and integrity verification of the packets sent by receivers, if any, is out of the scope of this document. This document defines an Experimental Protocol for the Internet community.
RFC6054 - Using Counter Modes with Encapsulating Security Payload (ESP) and Authentication Header (AH) to Protect Group Traffic: Counter modes have been defined for block ciphers such as the Advanced Encryption Standard (AES). Counter modes use a counter, which is typically assumed to be incremented by a single sender. This memo describes the use of counter modes when applied to the Encapsulating Security Payload (ESP) and Authentication Header (AH) in multiple-sender group applications. [STANDARDS-TRACK]
RFC6407 - The Group Domain of Interpretation: This document describes the Group Domain of Interpretation (GDOI) protocol specified in RFC 3547. The GDOI provides group key management to support secure group communications according to the architecture specified in RFC 4046. The GDOI manages group security associations, which are used by IPsec and potentially other data security protocols. This document replaces RFC 3547. [STANDARDS-TRACK]
