1. A communication apparatus for executing wireless communication complying with an IEEE 802.11 standard series by establishing a plurality of links with another apparatus, comprising:
one or more processors; and
one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the one or more processors to perform operations comprising:
updating an encryption key individually set for each of the plurality of links by executing predetermined processing including transmission of a predetermined message to the other apparatus,
wherein in the predetermined processing, the predetermined message including information associated with the encryption keys for at least two links among the plurality of links is transmitted to the other apparatus,
wherein the operations further comprise measuring, by using a timer, a time after the encryption key is updated, and
wherein in a case where the time measured by the timer reaches an update timing of the encryption key for one of the plurality of links, the encryption key for the corresponding link is updated.
