Senders encrypt their messages with this public key whose secret key is not known to anyone—not even a trusted third party—until a predefined and specific future time T+.delta., at which point the secret key is constructed and published. In one example, the secret key can only be known after it is constructed. At or after that time, anyone can decrypt the cipher text using this secret key. In one embodiment, a method for cryptographic encoding is provided, including generation of cryptographic key components by a plurality of parties, where participation of the parties is verified. A public key is constructed from a plurality of key components."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for time-lapse cryptography","description":"In one embodiment, a Time-Lapse Cryptography Service is provided based on a network of parties.
