(PER)
ASN.1 encoding rules for
producing a compact
transfer syntax for data structures
described in
ASN.1, defined in 1994.
PER provides a much more compact encoding then
BER. It
tries to represents the data units using the minimum number of
bits. The compactness requires that the decoder knows the
complete
abstract syntax of the data structure to be
decoded, however.
