9.11.3.18C  Ciphering key data |R16|Word‑p. 701

The purpose of the Ciphering key data information element is to transfer a list of ciphering data sets from the network to the UE for deciphering of ciphered assistance data.
The Ciphering key data information element is coded as shown in Figure 9.11.3.18C.1, Figure 9.11.3.18C.2 and Table 9.11.3.18C.1.
The Ciphering key data is a type 6 information element, with a minimum length of 34 octets and a maximum length of 2675 octets. The list can contain a maximum of 16 ciphering data sets.

Value part of the Ciphering key data information element (octets 4 to n)
The value part of the Ciphering key data information element consists of one or several ciphering data sets.
The UE shall store the complete list received. If more than 16 ciphering data sets are included in this information element, the UE shall store the first 16 ciphering data sets and ignore the remaining octets of the information element.
Ciphering data set:
Ciphering set ID (octets 1 to 2)
This field contains the binary encoding of the ID identifying the ciphering set.
Ciphering key (octets 3 to octet 18)
This field contains the 128 bit ciphering key.
c0 length (octet 19, bits 5 to 1)
This field contains the binary encoding of the length, in octets, of the c0 counter. The maximum value for the length of the c0 counter is 16 octets.
Bits 8 to 6 of octect 19 are spare and shall be coded as zero.
c0 (octets 20 to k)
This field contains the binary encoding of the c0 counter.
E-UTRA posSIB length (octet k+1, bits 4 to 1)
This field contains the length in octets of the E-UTRA Positioning SIB types. A length of zero means E-UTRA Positioning SIB types are not included (see NOTE).
E-UTRA Positioning SIB types for which the ciphering data set is applicable (octets k+2 to p). Unassigned bits shall be ignored by a UE. Non-included bits shall be assumed to be zero by a UE.
