The capsule mounting means may be provided with one or more capsule receiving slots, each of which may receive one capsule. The plurality of capsule placing grooves can be regularly arranged or irregularly arranged, correspondingly, the plurality of capsules can be regularly arranged or irregularly arranged, and the plurality of capsules can be arranged according to actual needs by a person skilled in the art.
The capsule may be used to contain food materials to be cooked, such as rice, millet, beans, etc. Alternatively, a single food material may be stored in the capsule, or a mixture of multiple food materials may be stored. By packaging the food material to be cooked in the capsule, the pollution of various severe environments of the food material in transportation to the food material can be avoided, and the quality of the food material can be well maintained. In addition, the capsule is used on the cooking utensil, and the food material can be encapsulated by the capsule when the food material is just produced, so that a user can eat the freshest food material. In addition, substances beneficial to human bodies can be added into the encapsulated capsules so as to meet the needs of special people.
The capsule may be used to contain water. The water can be purified water or water added with substances beneficial to human body. For example, it may be sugar water or brine.
The capsule is provided with a radio frequency code which can be positioned at least one position of the side wall, the top wall and the bottom wall of the capsule. Wherein the radio frequency code can be stuck on the outer surface of the capsule, corresponds to the position of the radio frequency identification instrument arranged on the cooking utensil, and the like. The encryption stability of the radio frequency code is good, the encryption effect is good, the implementation is easy, and the engineering implementation is easy.
The radio frequency code may also be referred to as an identification tag, an identification tag card, an identification tag chip, an electronic tag card, an electronic tag soft card, or the like.
For example, S101 may be performed by a scanning apparatus. I.e. the cooking appliance may have scanning means for scanning the radio frequency code on the capsule placed in the capsule receiving slot. The scanning device can be realized by an electronic tag reading circuit board. For example, the scanning device is a radio frequency identification device. The data information may be a series of sequences or a string of characters, for example.
Illustratively, S102 may include: acquiring a first key and a second key; and determining the decryption key according to the first key and the second key. Wherein the decryption key may also be referred to as a public key.

Acquiring the first key and the second key may include: combining the N1 first short keys by using a first arrangement algorithm to obtain the first keys; and combining the N2 second short keys by using a second arrangement algorithm to obtain the second keys, wherein N1 and N2 are positive integers greater than 1.
In the memory of the cooking appliance, the first key and the second key may be stored in segments, for example, the first key may be stored in N1 segments, each segment may be referred to as a first short key, and N1 first short keys are stored out of order; the second key is stored in N2 segments, each segment may be referred to as a second short key, and N2 second short keys are stored out of order. Wherein N1 and N2 may be equal or unequal. As an example, let n1=n2=3, as shown in fig. 2 as one example of a memory segment. The random numbers shown in fig. 2 refer to: other information than the first key and the second key.
The N1 first short keys and the N2 second short keys may be read from the memory, and then rearranged according to a predetermined arrangement algorithm, to obtain the first key and the second key. For convenience of description, it is assumed in this embodiment that the first key is denoted as x, and the second key is denoted as y.
For example, taking the example of fig. 2, where n1=n2=3, it can be assumed that the first key x (n11+n12+n13) is reached and the second key y (n21+n22+n23).
Illustratively, if the first key is denoted as x and the second key is denoted as y, determining the decryption key based on the first key and the second key may include: and f1 (x, y) is used for calculating to obtain the decryption key, wherein f1 is a key function. That is, the decryption key may be determined based on the first key and the second key based on the key function.
Specifically, the decryption Key may be calculated by key=f1 (x, y), where Key represents the decryption Key and the Key function f1 is stored in advance in the memory of the cooking appliance.
Therefore, the decryption Key can be obtained through segmented reading and Key functions, which is equivalent to scattered storage and double encryption, and even if the hex file is illegally obtained, the decryption Key can not be obtained through disassembly. Furthermore, in order to prevent the hex file in the singlechip from being read, the encryption bit in the singlechip can be set when the program is burnt, so that the encryption bit cannot be read by a tool, and the decryption Key can be more effectively protected.
That is, the encryption bit storing the N1 first keys and the encryption bit storing the N2 second keys may be set to be unreadable by a tool.
Illustratively, S103 may include: and obtaining the capsule information of the capsule by using f2 (D, key), wherein f2 is a decryption function, D represents data information, and Key represents a decryption Key.
Specifically, the capsule information may be obtained by z=f2 (D, key), where Z represents the capsule information and the decryption function f2 is stored in advance in the memory of the cooking appliance.
The Memory may be a Read-Only Memory (ROM), so that illegal writing and illegal modification of the segment keys in the Memory can be prevented, and the security of the first key, the second key, the key function and the decryption function can be protected. For example, the Memory is an electrically erasable read Only Memory (Electrically Erasable Programmable Read-Only Memory, EEPROM).
If the capsule is used to hold the food material to be cooked, the capsule information in the embodiment of the present application may include at least one of the following: the name, variety, weight, production place, crop planting information, processing information, logistics information, cooking curve and corresponding water consumption of the food materials.
Wherein the cooking profile may represent a time-dependent relationship of a cooking parameter, which may include at least one of power, temperature, pressure.
Alternatively, the cooking profile may represent a time-dependent relationship of the cooking program. The cooking program may include: soaking, absorbing water, heating, keeping boiling, stewing and preserving heat. And it is understood that the cooking parameters of different cooking programs are different, e.g., at least one of power, temperature, and pressure of different cooking programs is different.
The corresponding water consumption can be the water consumption required when cooking the food material.
If the capsule is to contain the water, the capsule information includes at least one of: water quantity, water source information and pH value. The water amount information can be the weight or the volume of water, such as 100g or 100 ml. The source location information may be location information, for example, latitude/longitude information. The pH value may be also referred to as hydrogen ion concentration index, pH value, or the like, and the pH value is a positive number, for example, 6.9.
The cooking appliance may include a main control circuit board, and S102 and S103 may be performed by the main control circuit board. Specifically, after the radio frequency code is scanned, the electronic tag reading circuit board can send the read data information to the main control circuit board, and the main control circuit board executes the decryption process.
The embodiment of the application relates to a decryption process based on data information, and it can be understood that in the production process of a manufacturer, the decryption process can be performed through an encryption function, so that D=f3 (Z, key) is achieved, and corresponding radio frequency codes are manufactured according to the obtained data information D. Key is a decryption Key which is strictly kept secret by factories and the like.
Therefore, the embodiment of the application can obtain the capsule information of the radio frequency code on the capsule through a series of decryption operations, so that the safety of the capsule can be determined and the counterfeit can be avoided.
Illustratively, if the capsule contains food material, after S103, it may further include: and cooking the food materials in the capsule according to the capsule information. Specifically, the food material in the capsule may be added to the pan and water is added through the sump or water capsule (or the user is instructed to add water) and the cooking process is initiated. For example, the capsule information includes a cooking profile according to which cooking may be performed. For example, the capsule information includes the variety and weight of the food material, a cooking profile may be determined, and then cooking may be performed according to the cooking profile.
Illustratively, if the capsule contains water, after S103, it may further include: water is added to the pan and the cooking process is started to boil the water. Alternatively, it may further include: adding water into the pan, adding food material through the food material capsule or instructing the user to add food material, and starting the cooking process.
And, it can be appreciated that the encrypted capsule can only be identified by the authenticated cooking appliance. While other card readers compatible with the chip can read the data information, the read data information is meaningless messy codes. On the other hand, the authenticated cooking appliance can be set to only identify the corresponding encrypted capsule, and other capsules cannot be correctly identified and verified, but can be regarded as illegal capsules and cannot be used.
