1. A device, comprising:
one or more processors configured to:
identify a set of characteristics of a frame;
compute a first key index associated with the frame based on the set of characteristics and using a first key index function;
determine whether the first key index is associated with any collision entries from a set of collision entries of a collision entry table,
wherein the set of collision entries are generated and stored,
wherein a collision entry, of the set of collision entries, indicates whether a same key index could be computed for two frames having different characteristics, and
wherein based on determining that the first key index is associated with a collision entry of the collision entry table:
compute a resolution value based on the set of characteristics of the frame;
compare the computed resolution value to a set of resolution value entries of a collision resolution table; and
determine a second key index based on a resolution value entry, of the resolution value entries, that includes information matching the computed resolution value; and
determine a set of security parameters associated with the frame using the second key index.
