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.

Claim (Index 1):
A method by a first base station in a mobile communication system, the method comprising:\n generating a first security key associated with a second base station using a secondary cell group (SCG) counter value and a base security key of the first base station, data between a terminal and the first base station being encrypted based on the base security key received from a mobility management entity (MME); and transmitting the first security key to the second base station, wherein the first security key is used to generate a second security key by the second base station, which is used for encrypting data between the terminal and the second base station, wherein the SCG counter value is used to avoid key repetition, and wherein at least one cell associated with the first base station and at least one cell associated with the second base station are aggregated for the terminal.
