18 Ron Rivest's Cipher No.2
19 ------------------------
20
21Ron Rivest's Cipher No.2 (hereafter referred to as RRC.2, other people may
22refer to it by other names) is word oriented, operating on a block of 64 bits
23divided into four 16-bit words, with a key table of 64 words. All data units
24are little-endian. This functional description of the algorithm is based in
25the paper "The RC5 Encryption Algorithm" (RC5 is a trademark of RSADSI), using
26the same general layout, terminology, and pseudocode style.
27
28
29Notation and RRC.2 Primitive Operations
30
31RRC.2 uses the following primitive operations:
32
331. Two's-complement addition of words, denoted by "+". The inverse operation,
34 subtraction, is denoted by "-".
352. Bitwise exclusive OR, denoted by "^".
363. Bitwise AND, denoted by "&".
374. Bitwise NOT, denoted by "~".
385. A left-rotation of words; the rotation of word x left by y is denoted
39 x <<< y. The inverse operation, right-rotation, is denoted x >>> y.
40
41These operations are directly and efficiently supported by most processors.
42
43
44The RRC.2 Algorithm
45
46RRC.2 consists of three components, a *key expansion* algorithm, an
47*encryption* algorithm, and a *decryption* algorithm.
48
49
50Key Expansion
51
52The purpose of the key-expansion routine is to expand the user's key K to fill
53the expanded key array S, so S resembles an array of random binary words
54determined by the user's secret key K.
55
56Initialising the S-box
57
58RRC.2 uses a single 256-byte S-box derived from the ciphertext contents of
59Beale Cipher No.1 XOR'd with a one-time pad. The Beale Ciphers predate modern
60cryptography by enough time that there should be no concerns about trapdoors
61hidden in the data. They have been published widely, and the S-box can be
62easily recreated from the one-time pad values and the Beale Cipher data taken
63from a standard source. To initialise the S-box:
64
65 for i = 0 to 255 do
66 sBox[ i ] = ( beale[ i ] mod 256 ) ^ pad[ i ]
67
68The contents of Beale Cipher No.1 and the necessary one-time pad are given as
69an appendix at the end of this document. For efficiency, implementors may wish
70to skip the Beale Cipher expansion and store the sBox table directly.
71
72Expanding the Secret Key to 128 Bytes
73
74The secret key is first expanded to fill 128 bytes (64 words). The expansion
75consists of taking the sum of the first and last bytes in the user key, looking
76up the sum (modulo 256) in the S-box, and appending the result to the key. The
77operation is repeated with the second byte and new last byte of the key until
78all 128 bytes have been generated. Note that the following pseudocode treats
79the S array as an array of 128 bytes rather than 64 words.
80
81 for j = 0 to length-1 do
82 S[ j ] = K[ j ]
83 for j = length to 127 do
84 s[ j ] = sBox[ ( S[ j-length ] + S[ j-1 ] ) mod 256 ];
85
86At this point it is possible to perform a truncation of the effective key
87length to ease the creation of espionage-enabled software products. However
88since the author cannot conceive why anyone would want to do this, it will not
89be considered further.
90
91The final phase of the key expansion involves replacing the first byte of S
92with the entry selected from the S-box:
93
94 S[ 0 ] = sBox[ S[ 0 ] ]
95
96
97Encryption
98
99The cipher has 16 full rounds, each divided into 4 subrounds. Two of the full
100rounds perform an additional transformation on the data. Note that the
101following pseudocode treats the S array as an array of 64 words rather than 128
102bytes.
103
104 for i = 0 to 15 do
105 j = i * 4;
106 word0 = ( word0 + ( word1 & ~word3 ) + ( word2 & word3 ) + S[ j+0 ] ) <<< 1
107 word1 = ( word1 + ( word2 & ~word0 ) + ( word3 & word0 ) + S[ j+1 ] ) <<< 2
108 word2 = ( word2 + ( word3 & ~word1 ) + ( word0 & word1 ) + S[ j+2 ] ) <<< 3
109 word3 = ( word3 + ( word0 & ~word2 ) + ( word1 & word2 ) + S[ j+3 ] ) <<< 5
110
111In addition the fifth and eleventh rounds add the contents of the S-box indexed
112by one of the data words to another of the data words following the four
113subrounds as follows:
114
115 word0 = word0 + S[ word3 & 63 ];
116 word1 = word1 + S[ word0 & 63 ];
117 word2 = word2 + S[ word1 & 63 ];
118 word3 = word3 + S[ word2 & 63 ];
119
120
121Decryption
122
123The decryption operation is simply the inverse of the encryption operation.
124Note that the following pseudocode treats the S array as an array of 64 words
125rather than 128 bytes.
126
127 for i = 15 downto 0 do
128 j = i * 4;
129 word3 = ( word3 >>> 5 ) - ( word0 & ~word2 ) - ( word1 & word2 ) - S[ j+3 ]
130 word2 = ( word2 >>> 3 ) - ( word3 & ~word1 ) - ( word0 & word1 ) - S[ j+2 ]
131 word1 = ( word1 >>> 2 ) - ( word2 & ~word0 ) - ( word3 & word0 ) - S[ j+1 ]
132 word0 = ( word0 >>> 1 ) - ( word1 & ~word3 ) - ( word2 & word3 ) - S[ j+0 ]
133
134In addition the fifth and eleventh rounds subtract the contents of the S-box
135indexed by one of the data words from another one of the data words following
136the four subrounds as follows:
137
138 word3 = word3 - S[ word2 & 63 ]
139 word2 = word2 - S[ word1 & 63 ]
140 word1 = word1 - S[ word0 & 63 ]
141 word0 = word0 - S[ word3 & 63 ]

212Implementation
213
214A non-US based programmer who has never seen any encryption code before will
215shortly be implementing RRC.2 based solely on this specification and not on
216knowledge of any other encryption algorithms. Stand by.

11.1 23/08/96 - eay
2 Changed RC2_set_key() so it now takes another argument. Many
3 thanks to Peter Gutmann <pgut01@cs.auckland.ac.nz> for the
4 clarification and origional specification of RC2. BSAFE uses
5 this last parameter, 'bits'. It the key is 128 bits, BSAFE
6 also sets this parameter to 128. The old behaviour can be
7 duplicated by setting this parameter to 1024.
8
91.0 08/04/96 - eay
10 First version of SSLeay with rc2. This has been written from the spec
11 posted sci.crypt. It is in this directory under rrc2.doc
12 I have no test values for any mode other than ecb, my wrappers for the
13 other modes should be ok since they are basically the same as
14 the ones taken from idea and des :-). I have implemented them as
15 little-endian operators.
16 While rc2 is included because it is used with SSL, I don't know how
17 far I trust it. It is about the same speed as IDEA and DES.
18 So if you are paranoid, used Tripple DES, else IDEA. If RC2
19 does get used more, perhaps more people will look for weaknesses in
20 it.
