Abstract:
The Self-shrinking p-adic cryptographic generator (SSPCG) is a fast software stream cipher. Improved
cryptoanalysis of the SSPCG is introduced. This cryptoanalysis makes more precise the length of the period of
the generator. The linear complexity and the cryptography resistance against most recently used attacks are
invesigated. Then we discuss how such attacks can be avoided. The results show that the sequence generated
by a SSPCG has a large period, large linear complexity and is stable against the cryptographic attacks. This
gives the reason to consider the SSPSG as suitable for critical cryptographic applications in stream cipher
encryption algorithms.
