Challenge ::= SEQUENCE { owf AlgorithmIdentifier OPTIONAL, -- MUST be present in the first Challenge; MAY be omitted in -- any subsequent Challenge in POPODecKeyChallContent (if -- omitted, then the owf used in the immediately preceding -- Challenge is to be used). witness OCTET STRING, -- the result of applying the one-way function (owf) to a -- randomly-generated INTEGER, A. [Note that a different -- INTEGER MUST be used for each Challenge.] challenge OCTET STRING -- the encryption (under the public key for which the cert. -- request is being made) of Rand, where Rand is specified as -- Rand ::= SEQUENCE { -- int INTEGER, -- - the randomly-generated INTEGER A (above) -- sender GeneralName -- - the sender's name (as included in PKIHeader) -- } }
