Hash optimization for cryptographically generated address

Cryptographically generated addresses (CGA) are IPv6 addresses where the interface address bits are generated by hashing the address ownerpsilas public key [1]. Owner of the address uses the corresponding private key and signs messages sent from that address to assert ownership of the address. CGA is generated by recursive hashing and conformance of the computed hash depending upon the security level. In this paper we propose restructuring of the CGA format and optimization of hash computation of CGA using SHA-1[2] and MD5[3].
