Claim 12:
13. The composite encryption system of claim 12, wherein the second computing system includes a second processor communicatively coupled to a second memory storing instructions which, when executed by the second processor, cause the second computing system to:
receive, at the second computing system, the composite encrypted key;
decrypt, at the second computing system, each of the N-1 secrets with the associated encryption algorithm associated with the respective one of the N-1 secrets, wherein decrypting each of the N-1 secrets includes use of N-1 decryption keys;
decrypt, at the second computing system, the encoded content with the Nth encryption algorithm using an Nth decryption key; and
performing, at the second computing system, an exclusive-or operation on the encoded content with each of the N-1 secrets to decode the content.
