Method Detail

hasData

boolean hasData()

 Data should be encrypted by the application under the symmetric key in U and Cs
 

required bytes data = 1;

getData

com.google.protobuf.ByteString getData()

 Data should be encrypted by the application under the symmetric key in U and Cs
 

required bytes data = 1;

hasU

boolean hasU()

 U is the encrypted random value for the ElGamal encryption
 

required bytes u = 2;

getU

com.google.protobuf.ByteString getU()

 U is the encrypted random value for the ElGamal encryption
 

required bytes u = 2;

hasUbar

boolean hasUbar()

 Ubar, E and f will be used by the server to verify the writer did
 correctly encrypt the key. It binds the policy (the darc) with the
 cyphertext.
 Ubar is used for the log-equality proof
 

required bytes ubar = 3;

getUbar

com.google.protobuf.ByteString getUbar()

 Ubar, E and f will be used by the server to verify the writer did
 correctly encrypt the key. It binds the policy (the darc) with the
 cyphertext.
 Ubar is used for the log-equality proof
 

required bytes ubar = 3;

hasE

boolean hasE()

 E is the non-interactive challenge as scalar
 

required bytes e = 4;

getE

com.google.protobuf.ByteString getE()

 E is the non-interactive challenge as scalar
 

required bytes e = 4;

hasF

boolean hasF()

 f is the proof - written in uppercase here so it is an exported field,
 but in the OCS-paper it's lowercase.
 

required bytes f = 5;

getF

com.google.protobuf.ByteString getF()

 f is the proof - written in uppercase here so it is an exported field,
 but in the OCS-paper it's lowercase.
 

required bytes f = 5;

getCsList

List<com.google.protobuf.ByteString> getCsList()

 Cs are the ElGamal parts for the symmetric key material (might
 also contain an IV)
 

repeated bytes cs = 6;

getCsCount

int getCsCount()

 Cs are the ElGamal parts for the symmetric key material (might
 also contain an IV)
 

repeated bytes cs = 6;

getCs

com.google.protobuf.ByteString getCs(int index)

 Cs are the ElGamal parts for the symmetric key material (might
 also contain an IV)
 

repeated bytes cs = 6;

hasExtradata

boolean hasExtradata()

 ExtraData is clear text and application-specific
 

optional bytes extradata = 7;

getExtradata

com.google.protobuf.ByteString getExtradata()

 ExtraData is clear text and application-specific
 

optional bytes extradata = 7;

hasReader

boolean hasReader()

 Reader points to a darc where the reading-rights are stored
 

required .darcOCS.Darc reader = 8;

getReader

DarcOCSProto.Darc getReader()

required .darcOCS.Darc reader = 8;

getReaderOrBuilder

DarcOCSProto.DarcOrBuilder getReaderOrBuilder()

 Reader points to a darc where the reading-rights are stored
 

required .darcOCS.Darc reader = 8;

hasSignature

boolean hasSignature()

 Signature must come from a valid writer stored in the admin darc of the OCS
 skipchain. For backwards-compatibility, this is an optional field.
 But for every new write-request, it must be set.
 

optional .darcOCS.Signature signature = 9;

getSignature

DarcOCSProto.Signature getSignature()

 Signature must come from a valid writer stored in the admin darc of the OCS
 skipchain. For backwards-compatibility, this is an optional field.
 But for every new write-request, it must be set.
 

optional .darcOCS.Signature signature = 9;

getSignatureOrBuilder

DarcOCSProto.SignatureOrBuilder getSignatureOrBuilder()

 Signature must come from a valid writer stored in the admin darc of the OCS
 skipchain. For backwards-compatibility, this is an optional field.
 But for every new write-request, it must be set.
 

optional .darcOCS.Signature signature = 9;
