WebMar 18, 2015 · We introduce and instantiate a new cryptographic primitive, called non-interactive distributed encryption, that allows a receiver to decrypt a ciphertext only if a minimum number of different senders encrypt the same plaintext. The new functionality can be seen as the dual of the functionality provided by threshold cryptosystems. WebApr 9, 2024 · From this, PKCS #1 defines “primitive” functions that generate and manipulate keys, including: Integer to Octet String Primitive (12OSP) Octet String to Integer Primitive (OS2IP) RSA Encryption Primitive (RSAEP) RSA Decryption Primitive (RSADP) ...

WebThree is known as the generator. If we raise three to any exponent x, then the solution is equally likely to be any integer between zero and 17. Now, the reverse procedure is hard. Say, given 12, find the exponent three needs to be raised to. This is called the discrete logarithm problem. And now we have our one-way function, easy to perform ...
