....options; the additional implementation effort required to use these as MACs is very small; and the fact that such MACs do not involve encryption algorithms has favorable export implications. Because of these factors, MAC constructions based on these hash functions were adopted in Kerberos [20] and SNMP [13] and are proposed for IPSEC [18] In this paper, a new general attack is proposed which applies to all iterated MACs, including MAA and CBC MAC. It is a birthday attack on known textMAC pairs, which with a few additional chosen text MAC pairs, allows MAC forgery. An extension of the ....
....1. Indeed, the compression function in MD4 based hash functions is of the form H i = E x i (H i Gamma1 ) H i Gamma1 , which behaves as a random function (for fixed x i ) the addition here is modulo 2 32 . A variation of the prefix method with MD5 is used in Kerberos V5, under the name MD2.5 [20]. The 128 bit key K 1 is derived from a 56 bit DES key K by using DES as a keystream generator in Output Feedback Mode (OFB) with IV = 0. The MAC consists of the leftmost 64 bits of the 128 bit hash result. While the expansion does not thwart an exhaustive search for the DES key, it appears to ....

.... gss wrap( so that the corresponding SPKM tokens described below are called SPKM MIC and SPKM WRAP, respectively. Perhaps the best known GSS API underlying mechanism is one which has been designed based on the Kerberos Network Authentication Service (V5) 10, 14] This Kerberos based mechanism [13], currently an Internet Draft, is expected to be progressed to Proposed Standard status in the near future. The primary purpose behind the development of the Simple Public Key GSS API Mechanism (SPKM) was to provide a GSS compliant underlying mechanism which was based on a public key ....
....The primary purpose behind the development of the Simple Public Key GSS API Mechanism (SPKM) was to provide a GSS compliant underlying mechanism which was based on a public key infrastructure but was as similar to the Kerberos 5 mechanism as possible. This is because the Kerberos 5 GSS mechanism [13] is beginning to gain wide acceptance within the Internet community (and so a familiar, drop in replacement would be desirable) but its reliance on a symmetric cipher infrastructure (DES) means that it cannot support a nonrepudiation service and that secure timestamps must be available in the ....
