Abstract
A Secure, Reliable, and Decentralized Communication ('SRDC') system may initialize primary and auxiliary processes associated with a mobile application, including creation of an Obfuscated Symmetric Primary Key ('OSPK') and an Obfuscated Symmetric Auxiliary Key (“OSAK”). A cipher key manager may apply a two-way function f( ) to generate two subkeys: SPAK1 (designated (SPAK)) and SPAK2 (designated (SPAK)). (SPAK)may be encrypted using (SPAK)to obtain (E-SPAK). OSAK may be de-obfuscated to obtain Symmetric Auxiliary Key (“SAK”) and (E-SPAK)may be encrypted using SAK to obtain (EE-SPAK). A key obfuscator may be called to de-obfuscate OSPK to obtain Symmetric Primary Key (“SPK”). (SPAK)may then be encrypted using SPK to obtain (E-SPAK). The SRDC system may communicate with a CP mobile service and store (E-SPAK)in a storage service. Data Encryption Key (“DEK”) may be generated, encrypted with SPAK and stored in the keychain persistent store of the primary process.
