RFC.4359 - The Use of RSA/SHA-1 Signatures within Encapsulating Security Payload (ESP) and Authentication Header (AH)
26.01.2006
Abstract:
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.
