docsBpiCmtsAuthCmPublicKey
Module: DOCS-BPI-MIB
OID (symbolic): DOCS-BPI-MIB::docsBpiCmtsAuthCmPublicKey
OID (numeric): 1.3.6.1.2.1.10.127.5.1.2.2.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The value of this object is a DER-encoded RSAPublicKey ASN.1 type string, as defined in the RSA Encryption Standard (PKCS #1) [22], corresponding to the public key of the CM. The 74, 106, 140, and 270 byte key encoding lengths correspond to 512 bit, 768 bit, 1024 bit, and 2048 public moduli respectively. This is a zero-length string if the CMTS does not retain the public key.
What is docsBpiCmtsAuthCmPublicKey?
Holds this specific cable modem's DER-encoded RSA public key as retained by the CMTS, sized 74/106/140/270 bytes for 512/768/1024/2048-bit keys, or empty if the CMTS doesn't retain it. An operator checks this per-CM entry to confirm the CMTS captured the modem's key during authorization.
