Similarly, prior to transmitting the system information, a valid base station may calculate a hash value using the system information as input to a hashing function. The base station may transmit the calculated hash value (e.g., which represent or be included in a set of hash values) to the UE in an access stratum (AS) security mode command (SMC) message. The UE may determine whether the received system information was modified based on the hash value (e.g., by comparing the UE calculated hash value and the set of hash values received from the base station in the AS SMC). If the UE indicates a mismatch of hash information, the base station may re-transmit the system information (e.g., in an integrity protected message)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of system information modification using access stratum security mode command","description":"A user equipment (UE) may receive system information from a base station and may calculate a hash value using the system information as input to a hashing function.
