Null
A symbol that means nothing that is included within a message designed to confuse unintended recipients. Dummy letter, letter symbol, or code group inserted into an encrypted message to delay or prevent its decryption or to complete encrypted groups for transmission or transmission security purposes.

In cryptography, a sequence of symbols that controls encryption and decryption. For some encryption mechanisms (symmetric), the same key is used for both encryption and decryption; for other mechanisms (asymmetric), the keys used for encryption and decryption are different.

Decryption is the opposite of encryption and synonomous with decipher. It is the transformation of encrypted information back into a legible form. Essentially, decryption is about removing disguise and reclaiming the meaning of information.

(1) A public key cryptosystem developed by Rivest, Shamir, and Adleman (RSA). The RSA has two different keys: the public encryption key and the secret decryption key. The strength of RSA depends on the difficulty of the prime number factorization. For applications with highlevel security, the number of the decryption key bits should be greater than 512 bits. RSA is used for both encryption and digital signatures. (2) Resource utilization, resource allocation. See Rivest, Shamir, and Adleman (RSA).
