| Summary: | This paper presents simulation results on randomness test of a cryptographic one-to-many reversible mapping
between user space and the IPv6 address space. A one-to-many reversible mapping mechanism is developed
which may be embedded into a DHCPv6 (Dynamic Host Configuration Protocol for IPv6) server in the
stateful mode within an enterprise local area network (LAN). Each time a user accesses the network, the
DHCPv6 server is able to assign a dynamic IPv6 address. The dynamic address (obtained through one-to-many
mapping) is to protect the user from unwanted behavior analysis exploiting IPv6 addresses, thus
protecting user privacy. However, the dynamic address can be uniquely linked to the user (through many-to-one
reversible mapping) if the need arises. The randomness of the dynamic address (one-to-many mapping)
for IPv6 address assignment is evaluated based on uniformity using monobit (frequency) test, and avalanche
effect is evaluated using Hamming distance tests. Simulation results show that the randomness in terms of
uniformity (occurrence of 1's or 0's are around 50%) and the Hamming distance (the difference between
Interface IDs at approximately 50%) are accepted. The decision rule of randomness is set at the 1%
significance level with the Pvalue of monobit (frequency) test, and the Pvalue in Hamming distance tests is taken
to be more than 0.01. IPv6 addresses generated by a one-to-many reversible mapping mechanism are
considered to be random with a confidence level of 99%. |
