Struct DistributedTranscryptor 

pub struct DistributedTranscryptor { /* private fields */ }

A distributed PEP transcryptor system that extends super::types::Transcryptor with blinding factor support for generating session key shares in a distributed transcryptor setup.

All methods from super::types::Transcryptor are directly accessible via Deref.

Implementations

impl DistributedTranscryptor

pub fn new( pseudonymisation_secret: PseudonymizationSecret, rekeying_secret: EncryptionSecret, blinding_factor: BlindingFactor, ) -> Self

Create a new distributed PEP system with the given secrets and blinding factor.

pub fn system(&self) -> &Transcryptor

Get a reference to the underlying PEP system.

pub fn pseudonym_session_key_share( &self, session: &EncryptionContext, ) -> PseudonymSessionKeyShare

Generate a pseudonym session key share for the given session.

pub fn attribute_session_key_share( &self, session: &EncryptionContext, ) -> AttributeSessionKeyShare

Generate an attribute session key share for the given session.

pub fn session_key_shares( &self, session: &EncryptionContext, ) -> SessionKeyShares

Generate both pseudonym and attribute session key shares for the given session. This is a convenience method that returns both shares together.

Methods from Deref<Target = Transcryptor>

pub fn attribute_rekey_info( &self, session_from: &EncryptionContext, session_to: &EncryptionContext, ) -> AttributeRekeyInfo

Generate an attribute rekey info to rekey attributes from a given EncryptionContext to another.

pub fn pseudonym_rekey_info( &self, session_from: &EncryptionContext, session_to: &EncryptionContext, ) -> PseudonymRekeyInfo

Generate a pseudonym rekey info to rekey pseudonyms from a given EncryptionContext to another.

pub fn pseudonymization_info( &self, domain_from: &PseudonymizationDomain, domain_to: &PseudonymizationDomain, session_from: &EncryptionContext, session_to: &EncryptionContext, ) -> PseudonymizationInfo

Generate a pseudonymization info to pseudonymize from a given PseudonymizationDomain and EncryptionContext to another.

pub fn transcryption_info( &self, domain_from: &PseudonymizationDomain, domain_to: &PseudonymizationDomain, session_from: &EncryptionContext, session_to: &EncryptionContext, ) -> TranscryptionInfo

Generate a transcryption info to transcrypt from a given PseudonymizationDomain and EncryptionContext to another.

pub fn rekey<E>(&self, encrypted: &E, rekey_info: &E::RekeyInfo) -> E

where E: Rekeyable,

Rekey encrypted data from one session to another. Automatically works with any rekeyable type (attributes, long attributes, etc.)

pub fn pseudonymize<E>( &self, encrypted: &E, pseudonymization_info: &PseudonymizationInfo, ) -> E

where E: Pseudonymizable,

Pseudonymize encrypted data from one domain/session to another. Automatically works with any pseudonymizable type (pseudonyms, long pseudonyms, etc.)

pub fn transcrypt<E>( &self, encrypted: &E, transcryption_info: &TranscryptionInfo, ) -> E

where E: Transcryptable,

Transcrypt (rekey or pseudonymize) encrypted data from one domain/session to another. Automatically works with any transcryptable type (pseudonyms, attributes, JSON values, records, etc.)

pub fn rekey_batch<E, R>( &self, encrypted: &mut [E], rekey_info: &E::RekeyInfo, rng: &mut R, ) -> Result<Box<[E]>, BatchError>

where E: Rekeyable + HasStructure + Clone, E::RekeyInfo: Copy, R: Rng + CryptoRng,

Rekey a batch of encrypted data from one session to another. Automatically works with any rekeyable type (attributes, long attributes, etc.)

Errors

Returns an error if the encrypted data do not all have the same structure.

pub fn pseudonymize_batch<E, R>( &self, encrypted: &mut [E], pseudonymization_info: &PseudonymizationInfo, rng: &mut R, ) -> Result<Box<[E]>, BatchError>

where E: Pseudonymizable + HasStructure + Clone, R: Rng + CryptoRng,

Pseudonymize a batch of encrypted data from one domain/session to another. Automatically works with any pseudonymizable type (pseudonyms, long pseudonyms, etc.)

Errors

Returns an error if the encrypted data do not all have the same structure.

pub fn transcrypt_batch<E, R>( &self, encrypted: &mut [E], transcryption_info: &TranscryptionInfo, rng: &mut R, ) -> Result<Box<[E]>, BatchError>

where E: Transcryptable + HasStructure + Clone, R: Rng + CryptoRng,

Transcrypt a batch of encrypted data from one domain/session to another. Automatically works with any transcryptable type (records, JSON values, long records, etc.)

Errors

Returns an error if the encrypted data do not all have the same structure.
