Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A process for multiple level encipherment of a data block consisting of binary digits said process comprising the steps of: arranging a stream of binary digit data into a plurality of data segments; loading one data segment from said plurality of data segments into a cryptographic block ciphering device for first generating a block cipher; following the first generation of a block cipher, retaining a portion of said block cipher and combining it with another data segment to form a composite data block; loading said composite data block into a cryptographic block ciphering device for generating a composite block cipher; sequentially generating composite block ciphers from said data segments until said data stream is exhausted.
Claim 2
Dependent Claim
115 words
A process for multiple level encipherment of a data block consisting of binary digits said process comprising the steps of: arranging a stream of binary digit data into a plurality of data segments; loading one data segment from said plurality of data segments into a cryptographic block ciphering device for first generating a block cipher; following the first generation of a block cipher, retaining a portion of said block cipher and combining it with another data segment to form a composite data block; loading said composite data block into a cryptographic block ciphering device for generating a composite block cipher; sequentially generating composite block ciphers from said data segments until said data stream is exhausted.
