A terminal includes: a communicator that wirelessly performs encrypted communication with an access point; a processor; and a memory that stores at least one program executed by the processor and a key management table for storing a group key for the encrypted communication. The processor performs: acquiring the group key from the access point and storing the group key acquired in the key management table as a first group key; receiving a broadcast packet encrypted by the access point via the communicator; making a first determination as to whether the broadcast packet received is decryptable by using the first group key; and when it is determined, in the first determination, that the broadcast packet is not decryptable by using the first group key, generating information indicating that the first group key needs to be updated.
