Embodiment

[0082] 1. A method for securing communication between a Universal Integrated Circuit Card (UICC) and a terminal.

[0083] 2. A method as in any one of the preceding embodiments, wherein securing the communication comprises generating a secure shared session key.

[0084] 3. The method as in any one of the preceding embodiments, wherein securing communications comprises using the secure shared session key to encrypt communications between the UICC and the terminal.

[0085] 4. The method as in any one of the preceding embodiments, wherein generating the secure shared session key comprises deriving the secure shared session key from a shared ciphertext.

[0086] 5. The method as in any one of the preceding embodiments, wherein deriving the secure shared session key from the shared secret comprises generating a session secret from the secret.

[0087] 6. The method as in any one of the preceding embodiments, wherein deriving the secure shared session key comprises performing a p...

Abstract

A method and apparatus for securing the interface between a Universal Integrated Circuit Card (UICC) and a Terminal in wireless communications is disclosed. The security of Authentication and Key Agreement (AKA) and application level generic bootstrapping architecture (GBA) with UICC-based enhancements (GBA_U) procedures is improved. A secure shared session key is used to encrypt communications between the UICC and the Terminal. The secure shared session key generated using authenticating or non-authenticating procedures.

Description

technical field [0001] This application relates to wireless communication Background technique [0002] Authentication and Key Agreement (AKA) procedures are used to establish authentication and shared security keys for Wireless Transmit / Receive Units (WTRUs) in 3rd Generation Partnership Project (3GPP) communication networks. AKA provides secure mutual authentication between two parties. In addition, the UICC-enhanced application layer Generic Bootstrap Architecture (GBA) (GBA_U) based on the AKA program provides a way to enable application security. However, the AKA and UICC-enhanced application-level Generic Bootstrap Architecture (GBA) (GBA_U) procedures based on UICC do not secure the interface connecting the WTRU's Universal Integrated Circuit Card (UICC) and the terminal. During the AKA and GBA_U procedures, key key related material is passed from the UICC to the terminal. Thus, session keys (eg CK / IK and Ks_ext_NAF) are exposed during initialization provision for ...
