Analysis and an improvement proposal for the authentication system of SNMPv3
Mingming Li, Houqin Su · 2010
The weak security of the digital digest algorithm used in the authentication system of SNMPv3 has been analyzed, an improved suggest taking SHA-2 to replace SHA-1 and MD5 used originally in SNMPv3 has been presented, and more security in application of SHA-2 comparing to MD5 and SHA-1 is described in this paper. Furthermore, a general method of compressing 256 bits into 96 bits is provided that establishes a basis of being compatible with the length of SNMPv3 authentication code.
