Update histogram representation for VDAF-06 #36

Closed tgeoghegan closed 1 year ago

tgeoghegan commented 1 year ago

Taskprov currently has:

struct {
    DpConfig dp_config;
    VdafType vdaf_type;
    select (VdafConfig.vdaf_type) {
        case prio3_aes128_count: Empty;
        case prio3_aes128_sum: uint8; /* bit length of the summand */
        case prio3_aes128_histogram: uint64<8..2^24-8>; /* buckets */
        case poplar1_aes128: uint16; /* bit length of input string */
    }
} VdafConfig;

In VDAF-06, rather than taking a list of bucket boundaries, the Prio3Histogram VDAF just takes a length, which is the number of buckets.

Additionally, all these VDAF names have aes128 in them, which is also obsolete.

This mostly duplicates https://github.com/wangshan/draft-wang-ppm-dap-taskprov/issues/33.

Oops, I should have checked for existing issues! Please feel free to close this in favor of #33.
