In order to have a proper and secure communication, it is necessary to use transient key cryptography when we are working with critical issues. Generation of Digital Signatures is important to provide security at both the sender and receiver sides during the transmission if data. Transient key cryptography is a cryptographic technique that ensures security against plaintext attacks and proves authentication by timestamping method.

Transient-key cryptography resembles public-key cryptography in which keypairs are generated, which are assigned to time intervals. Transient-key cryptography gives security against chosen plaintext-attacks. Transient-key size is sufficient to protect the encryption and integrity keys generated by key-exchange method.

Advantages of Transient-Key Cryptography

  • The main use of Transient-key cryptography is to generate digital signatures that assert a given piece of data.
  • They do not depend on long-term security of the private keys.
  • In transient-key cryptography, the source of time is a consistent standard understood by all senders and receivers.
  • Using transient-key cryptography, data is digitally signed with a time value derived from Universal Coordinated Time (UCT) accurate to within a millisecond.
  • When the time interval in the transient-key system expires, a new public or private key is generated.
  • And the private key from the previous interval is used to digitally certify the new public key and then the old private key is destroyed.
  • A time biasing method is used in transient-key cryptography to interpolate the received times where the time values are given by a third-party source.
  • Transient-key cryptography provides easier and cost-effectively safeguards the integrity of our documents.
  • This kind of cryptography proves authenticity of electronic records to clients, counsel, regulators and even courts.
  • It is particularly used in Digital timestamping. Hence, cross-certification is possible with the help of transient-key cryptography.
  • Transient-key cryptography is one of the wireless security mechanism that provides: Encryption, Authentication, and Access control
  • Proper Authentication helps us to know who are using our documents, files etc. and encryption (by encryption protocol), prevents data from eavesdropping.
