ENCRYPTION

Under Homomorphic Scheme, Epk(m1)+ Epk(m2)= Epk(m1+m2)
Is there any algo or method I can use for the following operation:
m1 + Epk(m2)= Epk(m1+m2)
In this operation, both m1 and m2 are numbers. Can you add the
plaintext into the ciphertext without encryption or decryption?

For all respects, most of all, including the GSMA SIP an organization that represents most of the mobile operators out and continue to believe GSM very safe. In reality A5 / 1, the technology used to encrypt messages GSM was exposed to at least a decade. The sense of security seems to be based on [...]
