Abstract: A container corresponding to executable code may be received. The container may be executed in a secure computation environment by performing one or more operations specified by the executable code of the container. An instruction to terminate the executing of the container may be received from a high level operating system (HLOS) that is external to the secure computation environment. A determination may be made as to whether the container is associated with a preemption privilege and the executing of the container may be terminated after receiving the instruction from the HLOS based on the determination of whether the container is associated with the preemption privilege.

Abstract: A base key that is stored at a mobile device may be received. A first dynamic key that is based on the base key may be generated. First transaction data corresponding to a first transaction associated with the mobile device may be received. Furthermore, the first dynamic key may be updated to generate a second dynamic key based on a combination of the first dynamic key and the first transaction data corresponding to the first transaction. Authentication of a second transaction associated with the mobile device may be requested based on the second dynamic key.

Abstract translation: 可以接收存储在移动设备处的基本密钥。 可以生成基于基本密钥的第一动态密钥。 可以接收对应于与移动设备相关联的第一事务的第一交易数据。 此外，可以基于第一动态密钥和对应于第一事务的第一事务数据的组合来更新第一动态密钥以生成第二动态密钥。 可以基于第二动态密钥来请求与移动设备相关联的第二事务的认证。
