A concrete implementation of a secure obfuscator for a special encrypted ring signature (ERS) functionality is constructed. This ERS functionality is the sequential composition of Waterss ring signature scheme and linear encryption scheme. In the standard model
the proposed obfuscator satisfies average-case virtual black-box property (ACVBP)
which guarantees the preservation of the anonymity and unforgeability of the ring signature even if an obfuscated program is given to the adversaries.
