Abstract: The embodiments herein provide a method and system for creating a secure connection for a User Equipment (UE) in a wireless network including a UE, carrier aggregated with at least one first serving frequency served by a first eNB and at least one second serving frequency served by a second eNB. A unique non-repetitive security base key associated with the second eNB is generated using a freshness parameter and security key associated with the first eNB. The use of a different freshness parameter for each security base key derivation avoids key stream repetition. Further, a user plane encryption key is derived based on the generated unique non-repetitive security base key associated with the second eNB for encrypting data transfer over at least one data radio bearer.
